With a line transformer you realise the mandatory galvanic isolation of the voltage and
current supply between hazardous and non-hazardous areas and ensure the safety
connection data.

Function of the test circuit
for 2-wire:

By means of the test circuit the current
can be metered during normal opera-
tion without having to disconnect the
instrument. For that purpose you have
to connect an ammeter (for appli-
cations in hazardous areas; internal
resistance < 15 Ohm) to the test
+/- terminals.

Cable connection in the spring clip terminal

„

Cover the stripped wire ends with end splices.

„

Unscrew the case cover.

„

Loosen the cable gland using an open-end
wrench, wrench size 24.

„

Lead the cable through the cable gland into
the opened case head.

„

Press the corresponding plastic lever at the
spring clip terminal down using a screw driver,
so that the clamped contact will be released.

„

Lead the prepared flying lead into the opening
and let go of the plastic lever, so that the flying
lead will be squeezed inside the spring clip
terminal.

„

After connecting the individual wires, tighten
the cable gland and screw down the case
over.
