This section describes how to connect the power wires to the cage for DC powered
systems (that is, when the PS19 DC or PS19 DC-D power supply cards are installed in
the cage). For instructions on how to connect power wires to AC powered systems, see
page 2-25, Wiring AC Powered Systems
.
Figure 2-11
displays the wire connections for DC systems.
A bonding bar is connected by the manufacturer between:
„
The two positive (48VRTN) terminal lugs
„
The two negative (–48V) terminal lugs
„
The two GND terminal lugs
This allows several cages to be connected together in parallel with the H614 wire
harness supplied. There is no ground interconnection between different cages.
Therefore, the GND terminal lugs are not in use.

Before connecting the DC power wires, verify that:
•The positive and negative power conductors are NOT connected to the –48 VDC power
source and are NOT energized in any way.
•The H614 power wire harness (supplied by the manufacturer) are red for positive, black
for negative, 10AWG, and include ring terminals that retain wires onto the terminal lug
when the connection is loosened.
Do not connect the GND terminal lugs to master ground.
