Installation
4.4.3
Braking resistor installation
• The supply cables to the braking resistors carry a high voltage (approx. DC 900 V)
during rated operation.
• The surfaces of the braking resistors get very hot when the braking resistors are
loaded with P
N
. Choose a suitable installation location. Braking resistors are usually
mounted on the control cabinet roof.
4.4.4
ND line choke
Connecting ND series line choke
Installing optional
power components
Input contactor for several units
Connect a line choke for limiting the inrush current:
• For 5 or more 3-phase units
• For 2 or more 1-phase units

B.
• Install the line filter close to the inverter but outside the minimum clearance for cool-
ing.
• Restrict the cable between the line filter and the inverter to the absolute minimum
length required, and never more than 400 mm (15.7 in). Unshielded, twisted cables
are sufficient.
• Use unshielded cables for the supply system connection as well.
