Terminals for connecting an optional braking resistor
Note Before shipping, a resin plate is attached to each braking resistor connection ter-
minal to prevent incorrect wiring.
When connecting a braking resistor, always remove the resin plates with a pair of
long-nose pliers.

Ground terminal
Always use a ground terminal with one of the following ground resistances:
100
Ω
or less for 200-VAC class
10
Ω
or less for 400-VAC class.
(Connect also to the power supply neutral to conform to the EC Directives.)
Be sure to connect a grounding line to the FG terminal and also connect
directly to the FG terminal of the motor.
