Mounting on the DIN Rail
You can also mount the terminal base to a grounded mounting plate. Refer to
the XM-441 Expansion Relay User Guide for details.
1. Position the terminal base unit on the 35 x 7.5mm DIN rail (A) (A-B
pt no. 199-DR1 or 199-DR4) at a slight angle.
2. Make certain the side connector (B) is fully retracted into the base
unit.
ATTENTION
The XM-943 makes a chassis ground connection through the DIN rail. Use zinc
plated, yellow chromated steel DIN rail to assure proper grounding. Using
other DIN rail materials (e.g. aluminum, plastic, etc.) which can corrode,
oxidize or are poor conductors can result in improper or intermittent platform
grounding.
IMPORTANT
The XM-943 terminal base unit is mounted to the right of the XM module to
which it is providing additional relays.
Position terminal base at a slight angle and hook over the top of the DIN rail.
