This chapter describes how to correctly mount and connect the device. Note
the connection diagrams provided.
WARNING
Electric shock
Danger of death due to electrical voltage.
► De-energize device and system periphery and lock to prevent switching

Installing and wiring temperature sensors
The following sections describe how to install and wire the temperature sen-
sors for the diverter switch oil and the transformer oil.
Connecting temperature sensor for on-load tap-changer oil
A temperature sensor is mounted in the on-load tap-changer head cover in
each on-load tap-changer. You have to perform the wiring in accordance
with the connection diagram that came with the motor-drive unit. Please ob-
serve the following:
Do not loop the temperature sensor connecting leads when laying because
this may cause voltage coupling and result in measurement errors.
To connect the temperature sensor for the on-load tap-changer oil, proceed
as follows:
1. Place the shielding of the sensor connecting lead on the grounding rails
in the motor-drive unit.
2. Connect the sensor connecting lead to the terminals in the motor-drive
unit as shown in the connection diagram.
