Installation and electrical connection
Measure the resistor of the electrode with an ohmmeter. The measured value must ap-
proach "infinity". For values ≤ 30 kOhm, if there is water in the oil – change the oil!

The single-phase current version is equipped with a shockproof plug. The connection
to the mains is established by inserting the plug into a socket. The plug is not overflow-
proof. Install the socket so that it is overflow-proof! Observe the information on the
protection class (IP) of the plug.
DANGER! If the pump is connected directly to the switchgear, dismantle the plug
and arrange for the electrical connection to be carried out by a qualified electrician!

For three-phase current motors, a clockwise rotating field must be available. The three-
phase current version is equipped with a CEE plug or with a bare cable end:
▪ If a CEE plug is supplied, connection to the mains is established by inserting the plug
into a socket. The plug is not overflow-proof. Install the socket so that it is overflow-
proof! Observe the information on the protection class (IP) of the plug.
▪ If there is a bare cable-end, the pump must be connected directly to the switchgear.
DANGER! If the pump is connected directly to the switchgear, arrange for the elec-
trical connection to be carried out by a qualified electrician!
