Screw a suitable cable gland into the conduit entry provided :

Model Code

Conduit Entry Thread

******A***

M20 x 1.5

******U***

3/4” NPT

Feed the 2 core cable into the enclosure and strip wire to reveal the 2 conductors

and the screen.

Connect the cable as shown in Figure iii below.

Figure iii Cable  connections

The terminals are ‘tension clamp’ type will accept up to 2.5mm

2 

conductors.  The

tension clamp type terminals provide constant force on the conductor of the

connecting cable and carry all necessary international approvals.
