'Inverter Drive' 3ph Motor Connection
3 x 230V Delta connection (inverter)
The motor should be configured as shown above
for connection to a 3 x 230V control panel.
Warning!
Ensure the correct motor connection
configuration is used to avoid damage
to the motor. Do not use '230 VAC Delta'
connection for 3ph/400VAC control panels.
Safety Circuit
The safety circuit combines the Thermal Trip and,
for operators with Manual Override, the Interlock
Switch.
The Thermal Trip is a heat sensitive switch
embedded in the motor windings that will operate
should the motor be overloaded.
The Hand Chain Interlock provides a means
of control circuit isolation to prevent electrical
operation whilst the door is being operated
manually.
Warning!
To ensure compliance with BS 7671 wiring
regulations (IET) the Thermal Trip must
be connected into the relevant controller
safety circuit (Stop circuit).
Note:- For operators with a disengage clutch, the
disengage switch output must be connected in
series with the motor safety circuit (N/C).
