with monitoring.
4-wire system (Triple stage, Common +ve): Connect
•
4 supply wires to the terminals as detailed in the wiring
diagram (1 common +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 common +ve and
stage 2 -ve terminals. Stage 3 is produced when
power is applied across the common +ve and stage
3 -ve terminals.
4-wire system (Dual stage, common –ve with
•
monitoring): 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 common
-ve and stage 1 +ve terminals. Stage 2 is produced
when power is applied across the common -ve and
stage 2 +ve terminals.
Monitoring functionality is obtained when the supply is
connected across M1 & M2 terminals.
Note: monitored terminals are not polarity dependent.
