INSTALLATION AND TESTING

Introduction

This section outlines the sequence for installing the PoE Power Rack, including plug-in

 

modules. Test procedures for verifying the integrity of the installation are also

 

included.

 

 

Guidelines

The device must be installed to allow sufficient front and rear access. All cables must

 

be routed through insulated conduit openings. All service operations can be

 

completed on the front of the power rack.

 

 

EMI Considerations

When running the DC output cables, ensure that the positive and negative cables are

 

routed so as no loops are created.

SafetyWARNING:

Only qualified personnel can install and service the PoE Power Rack.

Hazardous energy is present in the device and on the interface cables, which can cause electric shock, serious injury, or death if safety precautions are ignored. Follow all safety warnings and practices when servicing this equipment.

Installation Sequence Review all safety warnings in Section 3 before beginning the installation process.

Observe all warnings and labels on the equipment.
