Connect the wires to the AC terminal block on the three-phase delta AC PDM (see
). Loosen the input terminal or grounding point screw, insert each
wire into the grounding point input terminal, and tighten the screw (see
for approved AC wire gauge).
NOTE:
The terminal connections have either slotted screws or hex screws.
Use a 1/4-in. slotted screwdriver for the slotted screws. Use a 5/32-in.
(4-mm) Allen wrench for the 5/16-in. hex screws.
NOTE:
The three-phase delta AC PDM must be installed and secured in
the chassis before connecting the power input cables. If the PDM must
be removed, both input power cables must be uninstalled and removed
from the PDM before the PDM can be removed from the chassis. The
MX2008 chassis is not sensitive to phase rotation sequence—either
clockwise or counter clockwise will operate correctly.
To connect wires to the terminal block that serves six PSMs:
a. Insert the grounding wire into the grounding point labeled
GND
.
b. Insert the wire labeled
L1
into the input terminal labeled
A1
.
c. Insert the wire labeled
L2
into the input terminal labeled
B1
.
d. Insert the wire labeled
L3
into the input terminal labeled
C1
.
