Safety Guidelines
Observe the following safety guidelines when mounting the system in a
rack.
Rack Installation Warning: Install equipment in the rack from the bottom upward.
This will maintain the stability of the rack and reduce the chance of the rack’s
tipping over.
Heavy Equipment Warning: Three people are required to install the ERX system
in a rack: two to lift the system into position and one to screw it to the rack. The
system is extremely heavy.
Branch Circuit Warning: Evaluate the overall loading of the branch circuit before
you install any equipment into a rack.
Ground (Earth) Warning: Connect the ERX system or rack to ground (earth), and
ensure that a reliable grounding path is maintained in the rack.
Lightning Activity Warning: Do not work on the system or connect or disconnect
cables during lightning activity.
DC Power Disconnection Warning: Before powering on the ERX system,
remove power from the DC circuit by deactivating the circuit breaker on the panel
board that services the DC circuit.
Servicing Unit Warning: Before servicing the ERX system, turn off the power.
Jewelry Removal Warning: Remove jewelry (including rings, necklaces, and
watches) before working on equipment that is connected to power lines. Metal
objects heat up when connected to power and ground and can cause serious
burns or become welded to the terminals.
Metal Objects Warning: Do not insert any metal object, such as a screwdriver,
into an open slot or the backplane. Doing so may cause electric shock and serious
burns.
