4.10.1 Control Wiring

UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,
serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command,
an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-
tion.
-
Press [Off] on the LCP before programming parameters.
-
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
start.
-
Check that the drive, motor, and any driven equipment are in operational readiness.
• It is recommended that control wiring is rated for 600 V.
• Isolate control wiring from high-power components in the drive.
• If the drive is connected to a thermistor, for PELV isolation, ensure that control wiring is reinforced/double insulated.

Terminal Functions
Number
01, 02, 03 Relay 1 output. Usable for AC or DC voltage and resistive or inductive loads.
04, 05, 06 Relay 2 output. Usable for AC or DC voltage and resistive or inductive loads.
12, 13 24 V DC digital supply voltage. Useable for digital inputs and external transducers. To use the 24 V DC for digital
input common, programme parameter 5-00 Digital I/O Mode for PNP operation.
18, 19, 32, 33
Digital inputs. Selectable for NPN or PNP function in parameter 5-00 Digital I/O Mode. Default is PNP.
