The heater prevents humidity condensation inside the cabinet when the drive is not running.
The power output of the semiconductor-type heating elements depends on the environmental
temperature. The customer must switch the heating off when it is not needed by cutting the
supply voltage off.
The customer must supply the heater from an external 110…240 V AC power source.

￭ Cabinet lighting (G301)
This option contains LED lighting fixtures in each cubicle (except joining and brake resistor
cubicles) and a 24 V DC power supply. The lighting is powered from the same external
110…240 V AC power source as the cabinet heater (G300).
￭ Terminals for external control voltage (G307)
The option provides terminals for connecting an external uninterruptible control voltage to
the control unit and control devices when the drive is not powered.

￭ Output for motor space heater (G313)
The option contains:
• load switch for providing electrical isolation during service
• miniature circuit breaker for overcurrent protection
• terminal block for heater and external heater supply connection.
When the drive is powered (and not faulted), the heater is switched off. Otherwise, the heater
is controlled by the external supply voltage.
The power and voltage of the heater depend on the motor.

￭ Halogen-free wiring and materials (G330)
The option provides halogen-free cable ducts, control wires and wire sleeves, thus reducing
toxic fire gases.
￭ V-meter with selector switch (G334)
The option contains a voltmeter and a selector switch on the cabinet door. The switch selects
the two input phases across which the voltage is measured.
￭ A-meter in one phase (G335)
The option contains an ammeter that reads the current flowing through one input phase.
