NSTALLATION AND TESTING
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.
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.
When running the DC output cables, ensure that the positive and negative cables are
routed so as no loops are created.
WARNING:
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.
