# Mechanical Integration ### Overview

This document describes how to use oDynamo securely. Using the device in any way other than the approved methods described in this document invalidates the PCI PTS approval of the device.

Not following the guidelines in this section could damage the device, render it inoperable, and/or violate the conditions of the warranty.

This section provides information and guidelines for designing the mechanical aspects of a solution that incorporates oDynamo. MagTek strongly recommends vetting and testing solution designs before finalizing and deploying them, to make sure the design meets all requirements (e.g., functional, legal, security, certification, safety, and so on). When designing the mechanical portions of a solution that incorporates oDynamo, consider the following: * Review section 1.6 About oDynamo Components for an overall introduction to the device’s physical features and what they are called. * **Review Appendix A Technical Specifications.** * See section 3.2 Dimensions for overall device dimensions. * Design the solution enclosure front panel. Information about fitting the device into a panel cutout are in section 3.4 Panel Cutout. * Determine how the device will be mounted. See section 3.5 Mounting for details. Coordinate with the electrical design team to make sure the panel design, mounting hardware, and solution-specific installation instructions meet electrical requirements. * Coordinate with the electrical design team to plan cable routing and fastening. See section 3.6 Cabling for details. * Consider additional factors that do not fit these categories. See section 3.7 Miscellaneous Considerations. * Review safe handling practices in section 1.9 Handling to make sure the logistical aspects of the solution design meet the device’s handling requirements. * Review recommended installation practices in section 4 Installation. The steps provided in that section depend on the solution design team to customize the steps or fill in solution-specific details before distribution to installation technicians. * Review section 6 Maintenance. When installed in the solution-specific enclosure, the maintenance procedures may require modifications, or the solution may require additional maintenance not covered in the general guidelines provided here. * Review any additional requirements from other agencies, such as PCI certification requirements, building codes, and so on, which may introduce additional constraints to the design. ### Dimensions Overall dimensions of the device are shown in Figure 3-1. On request, MagTek can provide a 3D model of the device’s envelope to assist with the mechanical portion of solution design. MagTek strongly recommends building and testing prototypes with actual devices before finalizing the solution design.

### Orientation For optimum results, MagTek recommends orienting the device for horizontal card insertion (see Figure 3-2). Although it is possible to mount the device in vertical orientation, doing so may lead to impaired device function caused by the potential for increased accumulation of debris. Maintenance planning should take this into consideration.

The device must be installed such that cardholders have a full, unobstructed view of the housing around the card insertion slot opening (“entry zone”) prior to insertion. This is to allow cardholders to easily detect suspicious objects in or around the card slot entry, such as bugs / skimmers / tapping mechanisms, and their wires or antennas. Installation height is one factor in meeting this requirement: Assuming the solution design does not add features that obstruct the view of the slot, choosing the installation height involves making sure the nominal inspection position has a view of the device that is no greater than 55° above the horizontal plane of the device (measured from the plastic body), which provides a view similar to Figure 3-3. If the solution mounts the device at a downward pitch, subtract the pitch angle from the 55° before calculating. For example, if the nominal inspection position is 12” away from the device and 60” above the ground, and the device is mounted at 0° pitch, the device’s slot must be mounted no higher than 60”-(12”)tan(55°-0°)=43”.

The device incorporates a number of drain holes, shown in Figure 3-4. Drainage requirements are as follows: * The drain holes must not be obstructed. * The device must be oriented with the drain holes on the bottom. * The enclosure must pitch the device’s face between 0 degrees (level) and 30 degrees downward. It must not pitch the device’s face upward (see Figure 3-5, 0° ≤ θ ≤ 30°).

### Panel Cutout The device is designed to be integrated into a solution design that includes an enclosure to secure the device and protect it from the elements. This section provides guidelines for creating a cutout in the enclosure’s front panel that accommodates the device. The device’s installation face and gasket provide a seal against the elements: * The enclosure panel must be flat and rigid to produce a solid seal with the gasket and to provide security against tampering. * The solution’s enclosure must include a cutout that is sized to expose the device’s bezel while still squeezing the gasket. * The enclosure must protect the device from unauthorized tampering. * The enclosure must protect the device from the elements. The device is designed for ingress protection from the gasket forward, but the rear of the device behind the gasket must be protected. The device is sized for Compact Door Module hole patterns as specified by the European Vending Association (EVA) *Electronic Payment Specification for Unattended Point Of Sale (UPOS), EVA EPS 1.1*. Reference dimensions for the cutout in the solution enclosure, including the location of either screw holes or threaded studs, are shown in Figure 3-6; the outside dimensions of the sample cutout plate represent absolute minimum required clearances for the cutout’s overall placement in the enclosure. Detailed dimensions of the device’s installation face are shown in Figure 3-7.

### Mounting The solution design’s mounting hardware and torque specifications must apply adequate force to create a water-tight seal between the enclosure and the gasket. For example, for M4 nuts/bolts, the torque may be in the range of 0.7 N-m (6 to 7 in-lbs.). The device is designed to be mounted either onto screws (see Figure 3-9) or onto threaded studs permanently attached to the enclosure (see Figure 3-8), and nuts. The maximum shaft size for screws or studs is #10 or M5. Make sure mounting hardware in contact with the mounting holes conforms to the grounding requirements in section 2 Electrical Integration.

### Cabling This section provides information about mechanical integration of cables into a solution design. For details about electrical aspects of integrating the device, see section 2 Electrical Integration. The device incorporates cable tie mounts (see Figure 1-1) that can be used with cable ties (not included) to implement cable strain relief. See Figure 3-10 for an example of tying down cables.

Figure 3-10 - Cable Strain Relief

The enclosure should include adequate clearance for installation and maintenance personnel to connect and disconnect all cables. If the solution uses the device’s cable tie mounts for strain relief, it should provide additional clearance to remove and re-fasten the cable ties. It should also provide support for the device when cables are being connected and disconnected. Installation technicians will need to be provided detailed instructions for installing the cabling. For some basic guidelines, see section 4 Installation. ### Miscellaneous Considerations The device includes a label well (see Figure 1-1) around the General Status LED that can accommodate solution-branded labels. Labels should incorporate a cutout so they do not obstruct the LED. The device operates on low power, so no special cooling should be necessary. However, there must be adequate clearance around the vent holes in the top of the device’s body for heat to escape (see Figure 3-11), and the enclosure must not be an isolated thermal system that traps indefinite amounts of heat.
