ELECTRICAL CONNECTIONS
CAUTION
Switch the module off before connecting inputs and outputs.
To meet the electromagnetic immunity requirements:
- use shielded signal cables;
- connect the shield to a preferential instrumentation earth system;
- separate shielded cables from other cables used for power installations (transformers, inverters, motors, etc…).
POWER SUPPLY
The upper power supply limits must not be exceeded, as this might cause
serious damage to the module.
The power supply source must be protected from any failures in the module by
means of a suitably sized fuse.
INPUTS
Rheostat connection (2 wires):
Potentiometer connection (3 wires): 
NOTE: DIP 4 of DIP-SWITCH SW1 is reserved for internal uses.
OUTPUTS
INSTALLATION REGULATIONS
The module has been designed for vertical installation on a DIN 46277 rail.
For optimal operation and long life, adequate ventilation must be provided.
Avoid positioning ducting or other objects that obstruct the ventilation
slots. Avoid mounting modules over heat-generating equipment. Installation in
the bottom part of the electrical panel is recommended.
HARSH OPERATING CONDITIONS
The following constitute harsh operating conditions:
- High power supply voltage (> 30Vdc / > 26Vac).
- Sensor power supply at input.
- Using the impressed current output.
- When the modules are mounted side by side it may be necessary to separate them by at least 5 mm in the following cases:
- Panel temperature above 45°C in at least one of the above harsh operating conditions.
- Panel temperature above 35°C in at least two of the above harsh operating conditions.
