Control Wiring - Danfoss VLT AQUA Drive FC 202 Operating Manual

Electrical Installation

5.9 Control Wiring

All terminals to the control cables are inside the drive
below the LCP. To access the control terminals, either open
the door (D1h/D2h/D5h/D6h/D7h/D8h) or remove the front
panel (D3h/D4h).
5.9.1 Control Cable Routing
•
Isolate control wiring from high-power
components in the drive.
•
Tie down all control wires after routing them.
•
Connect shields to ensure optimum electrical
immunity.
•
When the drive is connected to a thermistor,
ensure that the thermistor control wiring is
shielded and reinforced/double insulated. A 24 V
DC supply voltage is recommended.
Fieldbus connection
Connections are made to the relevant options on the
control card. For more detail, see the relevant fieldbus
instruction. The cable must be tied down and routed along
with other control wires inside the unit.
