Installation

Wiring the system using multi-core cables

Note:

Read the installation instructions

Installation should only be carried

out by a suitably qualified Instal-

lation Engineer.

The intrinsically safe circuit must

not be earthed

When connecting more than 1 sensor it is

recommended that a junction box is used.

If a junction box is not used all cable joints

should be sealed using heat shrink tubing.

When connecting an ES8 sludge sensor an

external junction box should be used that

allows the shielded cable to be grounded

to earth.

When making connections between the

central control unit and a junction box this

should be interconnected using a multi-

core cable (6-core 1.0mm²) with connec-

tions made as shown in the following

diagram.
