Themountingbasehastwooptionsforwiring:wallorsurface-wiring,withwiresfromtherearorwiringfromthebottomor
sides.Forsafetyreasons,thepowersourcewiringandsignalwiresareseparatedandindifferentcompartmentsofthe
mounting base
- Ontheleftsidethesignalwiringislaidout(inputs,mainlysensors).
- Ontherightside,thepowersourceandearthwiringaresituated(powerandoutputrelaycontacts).

note
It is important that power supply lines are kept separate from signal/ data communications lines. This is to -
minimise the risk of electrical interference.

Whenwiringthroughthebottomorsideofthemountingbase,insulatedcablesmustbeused.Toensuresafety,
appropriate cable glands (not included with the System Controller) must be used.
Toinstallthecableglands,removethebreakoutportsfromthewiringholesattherequiredlocationinthebase.

note
That cable glands will t a range of cable diameters; therefore check to ensure that the proper combination is -
used.
