Installing the Drive
650V AC Drive
Motor Thermistor Connections
This input is provided to detect over-temperature in motors fitted with an internal thermistor.
There is no polarity to the thermistor connections.
IMPORTANT:
This input provides “Basic” insulation only to the SELV control circuits and assumes the
motor has “Basic” insulation to the windings/mains circuits.
The thermistor type supported is PTC `Type A’ as defined in IEC 34-11 Part 2. The drive uses
the following resistance thresholds:
Rising temperature trip resistance:
1650 to 4000
Ω
Falling temperature trip reset resistance:
750 to 1650
Ω
If the motor is not fitted with an internal
thermistor, you should disable the thermistor
trip function either by setting INVERT
THERMISTOR INPUT (
S
Ot) to 1, or by
linking the thermistor terminals.
Control Wiring Connections
Control wiring of between 0.08mm
2
(28AWG) and 2.5mm
2
(12AWG) can be used. Ensure all
wiring is rated for the highest system voltage. All control terminals are SELV, i.e. double-
insulated from power circuits.
