Chapter 2 Install the Adapter
Install the Adapter To install the adapter on the DIN rail prior to installing other XM terminal
base units, follow these steps.
1. Position the ControlNet adapter module (A) on a 35 x 7.5 mm DIN rail
(B) at a slight angle.
2. Hook the lip on the rear of the adapter onto the top of the DIN rail, and
rotate the adapter module onto the rail.
3. Press the adapter module down onto the DIN rail until flush. Locking
tab C will snap into position and lock the adapter module to the DIN
rail.
4. If the adapter module does not lock in place, use a screwdriver or similar
device to move the locking tab down while pressing the adapter module
flush onto the DIN rail, and release the locking tab to lock the adapter
module in place. If necessary, push up on the locking tab to lock.
5. Connect the adapter wiring. Refer to Wire the Adapter on page 15 .
ATTENTION
This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper
grounding. The use of other DIN rail materials (for example,
aluminum or plastic) that can corrode, oxidize, or are poor
conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200
mm (7.8 in.) and use end-anchors appropriately.
IMPORTANT
The 1440-DYN02-01RJ Dynamic Measurement module is used
with the 1440-ACNR. Any other XM catalog number will not
work with the 1440-ACNR.
IMPORTANT
The XM Bus must be terminated on each end with a 121 ohm,
1%, 1/4 W resistor. Because the adapter has an internal
terminator resistor, the second resistor must be connected to
the I/O module at the opposite end of the XM Bus.
