Connect up to 4 supply wires to the terminals as detailed
in the wiring diagram. Stage 1 is produced when power is
applied across the ve and stage 1 -ve terminals.
Stage 2 is produced when power is applied across the

wiring details (Types 9 & 10)
Noee: N This alternative configuration must be specified
when ordering the unit.
This type can be connected either as a three stage
common –ve configuration, or if an optional EOL is specified
if can be configured as a dual stage common –ve system
with monitoring.

4-wire sysoem (Triple soage, ve)e: Connect
4 supply wires to the terminals as detailed in the wiring
diagram (1 ve wire and 3 -ve wires). Stage 1
is produced when power is applied across the common
+ve and stage 1 -ve terminals. Stage 2 is produced
when power is applied across the ve and
stage 2 -ve terminals. Stage 3 is produced when
power is applied across the ve and stage
3 -ve terminals.
