7. Install the power supply(s). Always place the primary power supply in slot 15. If you have a
secondary power supply, place it in slot 14. See Figure 1. To install the power supply(s),
follow these steps:
a. Unplug the power cables or cord and turn the power switch off.
b. Insert the power supply firmly into its slot, then secure the screws.
• For an AC supply, plug the power cord into the front panel, then plug the cord into the
power source.
Caution: To prevent damage to the power supply or power source, do not reverse polarity,
and, if you use two DC power supplies, connect both DC sources to the same
ground.
• For a DC supply, loosen the screws for the GND and VDC terminals on the front panel,
then slide the wires under the square washers, and tighten the screws. See Figure 1.
Check the polarity and use an ohmmeter to verify that -48 VDC is not shorted to GND.
Replace the shield over the terminals on the front panel and connect the power cables to
the power source.
Note: The connector for the ESD grounding strap on the front of each power supply connects to
Earth ground through the chassis.
8. Insert the CIM in slot 0 and tighten the captive screw; see Figure 1. For details about
connecting the cables for the alarm relays or the chassis link in the domain, see the Model
1202 Chassis Interconnect Module User Manual.
9. If you have an optional DMM, insert it in an unused slot (slot 1 is recommended) and tighten
the captive screw; see Figure 1.
10. Insert the remaining modules into the chassis; for details, see the user manual for each
module.
11. Install a cover on each unused slot.
12. Turn on the chassis power supply(s). All LEDs on all modules light amber during the power-
on sequence, then the PWR LED lights green.
13. To configure each module in the chassis, see the user manual for that module.
