3.5. Cooling system
3.5.1. Fan configurations
The cooling system of the drive is equipped with one of the following fan configurations:
Non-redundant: The fan (1 in Fig. 19) is installed inside the cabinet.
–
Redundant: Fan 1 and fan 2 (1 and 2 in Fig. 20) are installed on the roof. This configuration
–
enables continuous operation of the drive if a fan fails.
3.5.2. Type of fan
The drive is equipped with one of the following types:
AC fans: The AC fans are turned on and off with digital signals which switch contactors to
–
connect or disconnect the 3-phase auxiliary power. The AC fan speed is not controlled.
EC fans: The electronically commutated (EC) fans are controlled via an analog signal from
–
the drive based on the inverter current. The EC fan speed is controlled depending on the
required cooling.
3.5.3. Starting, stopping the cooling system
The drive switches on the cooling system when the main circuit breaker (MCB) closes. When the
MCB opens, the cooling system switches off after a delay. The delay corresponds to the
discharging time of the drive and takes up to 5 minutes.
