Wiring the system using individual cables
When fitting an ultrasonic sludge
sensor a junction box should
always be used that allows the
equalisation of the earth potential
outside of the alarm control unit.
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 WGA-ES8 sludge
sensor an external junction box should be
used that allows the shielded cable to be
grounded to earth.
