PANELS
General
As an option, 3 cable side voltage transformers and/or
overvoltage deflectors can be fitted in a circuit-breaker
panel, see figure 1.
The primary side of the voltage transformers is connected
to the cable connection by means of a detachable epoxy
resin insulated connector. Connection data of the
secondary side are noted in the diagram pack for the
supplied installation.

ANGER WARNING
The cable side of the panel on which work is
being carried out must be earthed; for
instructions, see chapter 4.3.
The cable must not be live; check this by means
of the voltage indicator (see chapter 4.2.6).
On the secondary side of the transformer, the
fuses must be removed or the automatic cut-
outs turned off, so that feedback is impossible.
Disconnection
1. Make sure the cables are earthed and the transformers
isolated on the secondary side (see General).
2. Remove the protection cover.
3. Remove the 3 end caps and the 3 sleeves from the
epoxy resin insulated connection. An extraction tool is
available for removing the end caps (see chapter 7).
4. Loosen the 3 contact pins with a socket wrench (size 13)
and remove them.

OTE
If overvoltage deflectors are fitted as well as
transformers, they must also be disconnected.
The cable can now be tested or metered, for
example (see chapter 4.4).
Connection
1. Make sure the primary cables are earthed and the
transformers isolated on the secondary side (see
General).
2. Fit the 3 contact pins and tighten them with a socket
wrench (size 13); the tightening torque is 9 Nm.
