1. General
Before removing the terminal box module,
these fitting instructions should be studied
carefully. The installation and operation
should also be in accordance with local
regulations and accepted codes of good
practice.
Note: Pumps with modules must not be connected to
a frequency converter.
When fitted with a relay module, the pump can be
connected directly to a mains switch as it will be pro-
tected by the built-in overload protection at all three
speeds.
The relay module incorporates two indicator lights,
see fig. 1, and a signal output in the terminal block.
By means of a selector switch the signal output can
be set to activation during operation or fault, see fig.
