14 Installing the XM-220 Dual Speed Module
The terminal base can be DIN rail or wall/panel mounted. Refer to the
specific method of mounting below.
DIN Rail Mounting
Use the steps below to mount the XM-941 terminal base unit on a DIN rail
(A-B pt no. 199-DR1 or 199-DR4).
1. Position the terminal base on the 35 x 7.5mm DIN rail (A).
2. Slide the terminal base unit over leaving room for the side
connector (B).
ATTENTION
The XM modules make 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.
You can also mount the terminal base to a grounded
mounting plate. Refer to Panel/Wall Mount Grounding on
page 10.
Position terminal base at a slight angle and hook over the top of the DIN rail.
