2-4 Installation
Installing Your 1203-CN1 Module The following instructions explain how to physically install your
1203-CN1 module.
Important: To guard against device malfunction, you must wear a
grounding wrist strap when installing the 1203-CN1 module.
1. Set the module’s ControlNet node address by clicking the + or -
button to the desired value for each digit.
Important: Each node on the ControlNet network must have a
unique address.
Important: The node address must be set before power is applied
because the module uses the node address it detects when it first
receives power. To change a node address, you must set the new value
and then remove and reapply power to or reset the module.

2. Ensure the DIN rail to which the module will be attached is
connected to an earth ground.
Important: If EMC compliance is required, the DIN rail should be
properly grounded inside a full metal enclosure. The enclosure should
also be properly connected to an earth ground.
!
ATTENTION: When setting the node address, use a
blunt, pointed instrument. Do not use a pencil or pen
because lead (graphite) or ink may damage the switch
assembly.
