Installation precautions
2
All devices with DC power supplies are intended for installation in restricted access areas only. A
restricted access area is where access can be gained only by service personnel through the use
of a special tool, lock and key, or other means of security, and is controlled by the authority
responsible for the location.
For a DC system, use a grounding wire of at least 6 American Wire Gauge (AWG). The 6 AWG wire
should be attached to an agency-approved crimp connector crimped with the proper tool. The
crimp connector should allow for securement to both ground screws on the enclosure. For the
Ground lug, use UL listed Panduit crimp connector, P/N LCD6-10A, and two 10-32, PPH, screws
to secure crimp connector to chassis. The grounding position is located on the side of the chassis
adjacent to the ground symbol.
For the DC input circuit to the system, make sure there is a 30 amp circuit breaker, minimum
-48Vdc, double pole, on the input to the terminal block. The input wiring for connection to the
product should be Listed copper wire, 8 AWG, marked VW-1, and rated minimum 90 degrees
Celsius.
All devices with AC power sources are intended for installation in restricted access areas only. A
restricted access area is a location where access can be gained only by service personnel
through the use of a special tool, lock and key, or other means of security.
For a Brocade AC system, use a ground wire of at least 6 American Wire Gauge (AWG). The
ground wire should have an agency-approved crimped connector (provided with the chassis)
attached to one end, with the other end attached to building ground. The connector must be
crimped with the proper tool, allowing it to be connected to both ground screws on the enclosure.
Use a separate branch circuit for each AC power cord, which provides redundancy in case one of
the circuits fails.
