4. CHECKS BEFORE COMMISSIONING
Before commissioning the unit, check that:
•
the controller’s output current is greater than or equal to the rated or maximum current specified for the compressor;
•
the working voltage range is correct;
•
the power cables are sized correctly;
•
the cross-section and maximum length of the compressor cables are correct, and that these are connected in accordance
with the wiring diagrams;
•
all of the controller’s inputs are connected correctly.
•
the instructions on installing the individual system components have been followed;
•
the total maximum power of direct current (DC) fans complies with the value shown in the technical specifications table in
all operating conditions. Higher power consumption will cause permanent damage to the controller;
