Transporting transformer to the operating site
If the drive must be removed in order to transport the transformer, proceed
as follows:
1. Ensure that the drive and the on-load tap-changer / de-energized tap-
changer / ARS are in the adjustment position.
2. Remove the drive.
3. Do not actuate the drive while the on-load tap-changer / de-energized tap-
changer / ARS is decoupled and do not turn the output shaft.
4. Do not actuate the decoupled on-load tap-changer / de-energized tap-
changer / ARS and do not turn its drive shaft.
5. Transport the drive to the installation site in the MR delivery packaging.
6. Fit the drive and drive shaft to the transformer at the installation site in ac-
cordance with the respective instructions and check for correct coupling
and centering.

NOTICE Damage to motor-drive unit!
Damage to the motor-drive unit due to condensate in protective housing of
motor-drive unit.
► Always keep protective housing of the motor-drive unit tightly closed.
► In the event of downtime lasting more than 8 weeks prior to initial com-
missioning, connect and operate the anti-condensation heater in the mo-
tor-drive unit. If this is not possible, place a sufficient amount of desiccant
in the protective housing.
NOTICE Damage to the on-load tap-changer and motor-drive unit!
Damage to on-load tap-changer and motor-drive unit due to incorrect use of
position transmitter equipment.
► Only circuits stated in the chapter Technical data for position transmitter
equipment [ ► Section 13.2, Page 57] may be connected to the position
transmitter module connections.
► The switchover point of the position transmitter equipment in the motor-
drive unit is not the same as the switchover point of the diverter switch
operation. This depends on the type of diverter switch. This fact should
be noted when project planning the locking circuits between the motor-
drive unit and external equipment (e.g. transformer circuit breaker).
► Therefore, the "Tap changer in operation" position transit contact shown
in the connection diagram should be used for external monitoring, locking
and control purposes instead of the position transmitter equipment.
1. Commission motor-drive unit [ ► Section 6.1, Page 39].
2. Ensure correct function of motor-drive unit [ ► Section 6.2, Page 40].
