the wires. Insert the stripped ends of the cores perpendicularly
to the rear of the device into the terminals and secure them by
tightening the screw next to each one. As the channel for the
wire in the terminals is slightly curved, twisting the wires
slightly when inserting them is a help. Only insert one
stranded wire into each terminal.
Take care that no strands protrude that may cause arcing or
short-circuits.
· Bridging terminals:
Where it is necessary to bridge terminals, do so at external
terminals on the cubicle.

Connecting v.t. and c.t. circuits

Instructions for wiring the terminals
· Type and gauge of wire:
The v.t. and c.t. connections to the terminals are made with
2.5 mm
this case must be fitted with crimped sleeves.
V.t. and c.t. connections may be made alternatively by 4 mm
solid wire.
· Terminating the wires:
Insert the ends of the wires perpendicularly to the rear of the
device into the terminals and secure them by tightening the
screw next to each one.
Take care that no strands protrude that may cause arcing or
short-circuits.
· Bridging terminals:
Where it is necessary to bridge neighbouring terminals, do so
directly at the protective device using standard links (e.g. as
manufactured by PHOENIX). The terminals are designed to
accommodate these in addition to a 2.5 mm
ternatively, circuits have to be bridged at external terminals on
the cubicle.
