Manual for High Voltage Process Performance Motors

Operation - 45

3BFP 000 063 R0101 REV D

6.6 Shut down

When the machine is not in operation, anti-condensation heaters have to be switched on where
applicable. This is to avoid condensation effect inside the machine.

NOTE: Voltage may be connected to the terminal box for heating element.
