Repair switch

Overview
The G115D wall-mounted converter is optionally available with an integrated repair switch.
The repair switch allows the converter to be totally isolated from the mains. This means that
the mains power to the converter is terminated and the converter cannot start or stop the
motor.
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to five minutes until the capacitors
in the converter have discharged so that the residual charge is at a non-hazardous level.
• Wait at least five minutes to allow the converter to discharge after switching the repair
Note
The integrated repair switch in the G115D is listed as a manual motor controller suitable as
motor disconnect.
Although the activation of the switch while the motor is running is allowed, in order to
provide maximum protection to the converter, Siemens recommends that you stop the motor
by other means and wait until the motor reaches a full stop before activating the switch.
