Commissioning transformer at operating site
Checking motor-drive unit
Before commissioning the transformer, repeat the function tests on the mo-
tor-drive unit as described in MR operating instructions for motor-drive unit.
WARNING
Danger of death or severe injury!
Danger of death or severe injury due to incorrect operation!
► Under no circumstances is the transformer to be commissioned if the
functions specified in the section "Tests on motor-drive unit" are not
satisfied.
NOTICE Damage to the on-load tap-changer and motor-drive unit!
Damage to on-load tap-changer and 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 downtimes prior to initial commissioning of more than 8
weeks or operation interruptions of more than 2 weeks, connect and
operate the anti-condensation heater in the motor-drive unit. If this is
not possible (e.g. during transportation), place a sufficient amount of
dehydrating agent 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 may be connected to the position transmitter module con-
nections.
► 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).
► For external monitoring, locking, and control purposes, it is not there-
fore the position transmitter equipment but the "Tap changer in opera-
tion" position transit contact shown in the connection diagram that
should be used.
