Note:

Do not use asymmetrical motor cables. If there is a symmetrical grounding conductor in the motor
cable besides the conductive shielded layer, ground the grounding conductor on the VFD end
and motor end.

Braking resistor, braking unit and DC reactor are optional parts.

Route the motor cables, input power cables and control cables separately.

"Not available" means this terminal is not for external connection.

GD series VFDs cannot share the DC bus with CH series VFDs.

When sharing the DC bus, the VFDs must be the same in power and must be simultaneously
powered on or off.

In shared DC bus running mode, current balance on the VFD input side must be considered
during wiring, and equalizing reactors are recommended to be configured.

The PB is available for the 045G/055P–110G/132P models only when built-in braking units have
been selected for the 045G/055P–055G/75P models.

Function description
3PH AC input terminal,
connected to the grid.
3PH AC output terminal,
connected to the motor in
most cases.
P1 and (+) connect to
external DC reactor
terminals.
(+) and (-) connect to
external braking unit
terminals.
PB and (+) connect to
external braking resistor
terminals.
Grounding terminal for safe
protection; each machine
must carry two PE terminals
and proper grounding is
required.
