B Engage the ICM module with the top attachment
screw and secure with the 2 lower screws.
B Installing conduit:
• On the conduit interface punch out the required
number of penetrations by knocking cautiously with a
screwdriver handle;
• Remove all plastic grommets from the slots on the
lower side of the ICM and discard;
• Install the conduit interface by sliding the rails into
the intended slots.
• Install the conduit and sensor wire strain relief
according to the manufacturer's instructions.
NOTE:
B When using the conduit interface, no
plastic grommets are required.

Making the electrical connections

B Observe all national and local electrical code for the
line voltage connections and use at least cable
AWG14 for the main power cord.
B Connectors can be removed from the contact strip for
easy connection of the wires to the screw terminals.
The connectors are color-coded and keyed to prevent
mismatch of cable terminals.
3.2.1 Connection of the low voltage part with BUS
connections
CAUTION: Malfunction!
B Always wire in accordance with the
wiring diagram (
B Never connect one BUS to another.
Cable length
max 650 ft (200 m)
Table 6 Minimum permissible cross-section of the 2-wire
BUS connections
B Route all low-voltage cables separately from cables
carrying 120V to avoid inductive interference
(minimum separation 4", (100 mm)).
B In case of inductive external influences, use shielded
cables.
This way, the cables are shielded against external
influences (e.g. high-voltage cables, contact wires,
transformer stations, radio and TV devices, amateur
radio stations, microwave devices, etc.).
B When sensor leads are extended, apply the following
lead cross-sections:
Cable length
max 100 ft (30 m)

B Use conduit strain relief to safeguard sensor wires.
CAUTION: Risk of pole reversal.
Malfunction from interchanged connection
on the 0 - 10 V interface.
B Ensure connection to the correct poles
(9 = negative, 10 = positive).
