58 Electrical installation

Routing the cables

 General rules

Ideally, the input, output and control cables should be installed on separate trays.

If control cables must cross over power cables, arrange them at an angle as near to

90 degrees as possible. Try to ensure that control cables and power cables (AC and

DC) are kept at least 20 cm (8 inches) apart. Do not run any cables behind the

inverter.

Metal cable trays must be electrically bonded to each other and to the grounding

electrodes. Aluminium tray systems can be used to improve local equalizing of

potential.

Checking the insulation of the assembly

Note: The inverter always measures the impedance between the DC terminals and

ground before establishing a grid connection. If the impedance is less than 900 kΩ, a

No. Cable type
