Power Electronics V5 Series Getting Started Manual page 11

The V5 protects the motor with electronic overload sensing, so an external overload relay is not necessary. If multiple
motors are connected, separate overloads are required for each motor.
An isolator can be fitted after the V5 but is recommended for off load use only. Whilst a motor isolator is not
necessary for the operation of the V5, site standards or electrical wiring regulations may require this to be installed.
If a contactor is to be fitted, one of the V5 output relays can be used to energise this on receiving an external start
signal. (G7.1 Relay 1 = 11 Instantaneous).
Note: It is absolutely necessary that the installer guaranties the correct observance of the law and the regulations that
are in force in those countries or areas where this device is going to be installed.
