Connections for pump over temperature protection (where supplied with pump).
Note:
to realize the pump motor winding over temperature protection, it requires that there must be over-
temperature switches embedded in the pump motor winding (microtherms as fitted to Zenit 3ph pumps 2.2
kW or greater)
. To utilise the pump’s over temperature protection connect the pump’s microtherm leads to
terminals 9 and 11, 10 and 12 and remove the jumper.
Note:
if the pump is without over temperature switch, please use jumper to connect terminals 9 and 11, 10
and 12.
