4.3 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.
4.4 Installing float switches and probes.
Float switch installation.
Do not encase sensor leads, float switches or signal cables in metal pipes. Use PVC or PE tubing.
Liquid probe installation.
In event of high risk of electrical storms (lightning) or when liquid medium in sump, well or tank is very
dirty, it is recommended to use float switches.
