Example connection diagram
115 V AC control voltage (G304)
The option replaces control voltage 230 VAC with 115 VAC. 115 VAC control
voltage is provided when needed with oC129 and +C134.
Terminals for external control voltage (G307)
The option provides terminals for connecting external control voltage.
Note: The external control voltage is not supplied to the fans and, in ACS800-07
frames n×R8i, to the Diode Supply System Board (DSSB).
Output for motor heater (G313)
The option contains a padlockable load switch, a miniature circuit breaker for short
circuit protection and a terminal block for external supply and heating element(s)
connection.
Frames R5 to R8: The customer controls the heating elements in the motor windings
on and off with the external supply.
Frames n×R8i: The drive controls the heating elements on when the drive is not
running and off when the drive is on.
The power and voltage of the motor heater depend on the motor.
More information: For the terminal block type, see Additional terminal block X2
(+L504) , page 33 .
