Grounding Capacitor Switching Method - Toshiba VF-PS1 Instruction Manual

Charge lamp
Charge lamp is inside the unit front cover open. Never remove the front cover while power is on or within 15
minutes after power off, nor turn on the power while the front cover is open. They can result in electric shock.
Location of charge lamp depends on type form.

1.3.3 Grounding capacitor switching method

The inverter is grounded through a capacitor. The leakage current from the inverter can be reduced using the
switching switch on the main circuit terminal board. This switching device is used to detach the capacitor from the
grounding circuit or to reduce its capacitance.
Some models have capacitors that can be detached completely, while others have capacitors whose capacitances
can be reduced.
VFPS1-4007PDE to 4220PDE don't have this switch.
Note 1: Please note that, without the capacitor, the inverter does not comply with the EMC directive.
With default setting, PLE type drives comply with EN55011 class A, and PDE type drives comply with
EN55011 class B. For detailed information, refer to 7.1.1.
Note 2: When attaching or detaching the capacitor, be sure to turn off power.

Prohibited
A switch enables to detach the grounding capacitor. However, if you are using one of VFPS1-4007PLE~4055PLE
inverter, or one of 4075PLE~4220PLE inverter with the cable between inverter to the motor which length is 100m or
more, detaching the grounding capacitor must be followed with setting the carrier frequency (CF) at 4kHz or less.
Be sure to read the above precaution.
Charge lamp
If you are using one of VFPS1-4007PLE~4055PLE inverter, or one of 4075PLE~4220PLE
inverter with the cable between inverter to the motor which length is 100m or more, in
case of detaching the grounding capacitor, be sure to set the carrier frequency (CF) at
4kHz or less. If the carrier frequency is set above 4kHz, internal parts of the inverter may
overheat and be damaged.
