The system’s ATMs mount on a standard DIN rail (not provided). Mount ATMs
within the length of the provided cable from the control’s main chassis, leaving
adequate service loop.
1. Obtain a DIN rail strip. Cut it to the desired length and mount it to a panel.
Leave sufficient space between the DIN rail and walls, objects, etc. for easy
access.
2. Drill and tap at least two holes per foot (1 hole every 15 cm) and install DIN
rail, using the appropriate screws and washers.
3. Verify that the DIN rail is at earth ground potential (connected to a panel that
is at earth ground potential). If the DIN rail is not at earth ground potential
4. connect it to earth ground via a 12 AWG (4.0 mm²) or larger green/yellow
wire or braid; keeping the wire/braid as short as possible.
5. Snap the ATMs onto the DIN rail.
6. Snap the included ground terminals (Misc A) onto the DIN rail next to the
ATMs. See Figure 3-8.
7. Connect a 12 AWG (4.0 mm²) green/yellow wire between each ground
terminal and ATM terminal “Chassis Ground”. This wire should be kept as
short as possible and be no longer than six inches (15 cm) in length.
