PSE-AD-1 PSU
(See Figure 200-32)
NOTE:
Before proceeding, ensure the Power Line
Cord is not plugged into the AC receptacle
and the system AC power switch located in
the left front side of the ESE-32B-1 CCU,
(just above the card slots), is in the
OFF
(down) position. The three prong, AC Power
Line Cord is factory provided and is
connected to the terminal block located at
the left side of the ESE-32B-1 CCU.
A. Remove the four mounting screws (located at the
top and bottom of the PSU slot), in each CCU.
Place the screws aside for later PSU installation.
B.
Install a PSE-AD-1 PSU into the PSU slot in each
CCU, as shown in Figure 200-32, making sure its
power switch is in the
OFF
position.
C. Secure each PSU with the four screws previously
removed in Step A.
D. Two cables are provided on each PSE-AD-1 PSU.
One is a 3 pin connector ended for AC input, the
other is a 6 pin connector ended DC output.
Connect the AC cable into any of the AC connectors
(J6- JS)
located immediately above the corresponding
ESE-32B-1 CCU card slots. (See Figure 200-33).
Connect each DC IN power cable of each PSUto the 6
pin (54) connector located immediately above its
corresponding CCU. (See Figure 200-33).
E.
Plug the three-prong AC power line cord into the
117V AC receptacle and check the DC output
voltages, which can be read on the corresponding
6 pin connector (54) of each CCU or at the CPU
and MMC test points, in accordance with Figure
