Installation
3. Make sure that the mounting surface of the cutout is smooth and cleaned from
any burrs or debris.
4. Install the operator panel into the cutout.
5. In cases where the front panel seal is critical, use a torque wrench to ensure all
screws are torqued within the specification above.
6. Connect the cables in the specified order, according to the drawing and steps
below.
Caution:
•
The operator panel must be brought to ambient temperature before it is started
up. If condensation forms, ensure that the operator panel is dry before connecting
it to the power outlet.
•
Ensure that the operator panel and the controller system have the same electrical
grounding (reference voltage level), otherwise errors in communication may
occur.
•
Ensure that the voltage and polarity of the power source is correct.
•
Separate high voltage cables from signal and supply cables.
•
Shielded communication cables are recommended.
