5.1
Installation
The voltage regulator is suitable for both flush and projected
panel mounting (see dimension diagram). Be sure to install
the device in an easily accessible place in the control room or
in a switching cabinet attached to the transformer.
5.2
Connection
The voltage regulator is to be connected in accordance with
the wiring diagram (see Appendix).
When connecting the equipment, please pay attention to:
– the correct phase angle of the secondary terminals of
current transformer and potential transformer
– correct connection of the output relays to the motor
drive unit
– correct connection to earth of the housing.
The voltage regulator is normally fed by the voltage trans-
former.
Connect the voltage transformer to terminals 1 and 2, and
the auxiliary voltage to terminals 3 and 4 (see
fig. 5
).
The TAPCON
®
230 VC is optionally available with a supply
input of AC 230 V preset at the factory.
WARNING
Take care to properly connect the voltage regulator and
the housing to ground. Danger to life.

NOTES
When using an auxiliary voltage AC 115V, 50...60Hz, be
sure to remove the links between terminals 1/3 and 2/4:
NOTE
The TAPCON
®
230 VC was developed in accordance with
the relevant EMC standards. The following instructions
must be observed to ensure preservation of the EMC
properties:
– Ensure correct connection to ground by means of the
ground screw attached to the housing, wire section not
less than 4mm².
– Be sure to lead the individual power circuits (motor-
drive control, inputs, outputs) in separate cables.
– Be sure to use only shielded cables for the parallel
operation data links
for the remote tap position
indication of the motor-drive unit.
The screenings at
both line ends must be connected to ground via the
grounding angle cable clamps at the housing included
in the delivery (see
fig. 6
)
