Connecting the Switch to the AC-Input Power Supply
Installing the AC-input Power Supply on a DIN Rail, Wall, or Rack Adapter
You install the AC-input power supply on a DIN rail, wall, or rack as you would a switch module. You
should first attach the AC-input power supply to the switch and then install the entire switch assembly
on the DIN rail, wall, or rack adapter. For more information, see the
“Attaching the Power Supply to the
“Installing the Switch on a DIN Rail” section on page B-30
, the
“Installing the Switch on a Wall” section on page B-34
“Installing the Switch in a Rack” section
Warning
This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is
suitably designed for those specific environmental conditions that will be present and appropriately
designed to prevent personal injury resulting from accessibility to live parts. The interior of the
enclosure must be accessible only by the use of a tool.
The enclosure must meet IP 54 or NEMA type 4 minimum enclosure rating standards. Statement 1063
Caution
To prevent the switch assemble from overheating, there must be a minimum of 3 inches (76.19 mm)
between any other device and the top, bottom, or sides of the switch assembly.
Connecting the DC Power Clip
The DC power clip (PWR-IE3000-CLP=) is a prewired cable that connects DC power from the power
converter to the switch module. Because the power clip uses the Pwr A connector, you cannot use the
alarm connections on that connector.
Follow these steps to connect DC power from the AC-input power supply to the switch module.
Step 1
Locate the DC power clip in the AC-input power supply accessory kit.
Step 2
Position the power clip so that the two-pin connector is over the power converter and the four-pin
connector is over the switch Pwr A connector, and then slide the power clip into these two connectors.
Step 3
Use a ratcheting torque flathead screwdriver to tighten the captive screw to 2.2 in-lb (0.25 Nm).
Caution
Do not over-torque the power and relay connector captive screws. The torque should not exceed 2.2 in-lb
(0.25 Nm).
