A terminal block is supplied to enable multiple connections to BO/B2 as detailed in product
wiring connections.
0-10V outputs and remote switch inputs should be connected by 0.75mm
2
cable of maximum
length 100m.
The remote temperature sensor may be placed at a distance of up to 100m (maximum) from the
control unit, using screened 0.75mm
2
cable to improve noise rejection. Connect the screen to
terminal B0. Master-slave communication is by screened twisted pair cable, RS 485 compatible,
such as Belden 9841. Maximum overall system length is 500m. Connect screens to B0 and C0.
All sensor and signal wiring should be kept separate from mains wiring to minimise noise pick-up.
