Optional switchgear and controlgear

The operating personnel must be informed about the types of switches
present in the drive and the parameter settings for opening and closing.
8.8.1

DC-link disconnector

Drives can be equipped with a manual controlled DC-link disconnector.
The location of the control switch for opening and closing depends on the
configuration of the drive. The control switch can be actuated when
released by the drive.
8.8.2

Output switches

Drives can be equipped with motorized output disconnectors, or
motorized or manually-operated output grounding switches.

NOTICE
Risk of component damage!
• The operator must ensure that the motor does not rotate before the
switch is actuated.
The switches for actuating the manual output switches are installed
inside the drive cabinets. The location depends on the configuration of
the drive. The switches are accessible after the DC link has been
discharged and the doors have been opened. The open and closed
position of the switches is monitored by the drive.
Depending on the operating state of the drive and the settings of the
parameters for this function, the drive opens or closes the
motorized switches.
8.8.3

Manual output isolation

The manual output isolation (MOI) disconnects the output of the drive
from the motor and creates a visible isolating distance in the supply line
to the motor.
Note: For more information, see "9.4.9 Drives with the manual output
isolation (optional)" on page 206.
