3.
Make sure to select the mains cable and the output cables correctly.
For information on cable selections, see
4.
Make sure that the control cables are as far as possible from the power cables.
5.
Make sure that the shields of the shielded cables are connected to a grounding terminal that is identified with the grounding
symbol.
6.
Do a check of the tightening torques of all the terminals.
7.
Make sure that the cables do not touch the electrical components of the drive.
8.
Make sure that the common input +24 V is connected to an external power source.
9.
Make sure that the digital input ground is connected to your digital system ground when floating, or to the control terminal
ground.
10.
Check that the coolant inlets and outlets are connected according to instructions.
11.
Open the shut-off valves.

PRE-CHARGING NEEDED
The system modules do not have an internal DC-link charging circuit. If the drive is connected to the supply voltage without first
pre-charging the DC-link capacitors, the inrush current can damage the equipment.
Before closing the main switch and connecting the drive to mains, pre-charge the DC-link capacitors of the system modules.
