EXTERNAL SWITCH OR CIRCUIT-BREAKER AND EXTERNAL OVERCURRENT
PROTECTION: The module is allowed to be connected to installation with over
current protection that has nominal value of 16 A or less.
RECOMMENDATION ON SWITCH OR CIRCUIT-BREAKER PROTECTION: There should
be two poles main switch in the installation in order to switch off the module.
The switch should meet the requirements of standard IEC60947 and have a
nominal value at least 6 A. The switch or circuit-breaker should be within easy
reach of the operator. It should be marked as the disconnecting device for the
equipment.
All connections, module attachments and assembling must be done while module
is not connected to the main power supply.
Wires connected to the module must have cross sectional area at least 0.75 mm

.
Minimum temperature rating of wire insulation must be 85 °C
1. Switch OFF main power supply.
2. Mount module to the provided place inside an electrical panel (DIN EN50022-35 rail
mounting).
3. Mount other IO modules (if required). Mount each module to the DIN rail first, then attach
modules together through K1, K2 connectors.
4. Connect needed input, output and communication wires.
5. Switch ON main power supply.
Dismount in reverse order. For mounting/dismounting modules to/from DIN rail a free space of at
