Every time the relay trips the pump, the pump needs to be inspected and its
insulation resistance measured.
The electrode relay (K1) must meet the following requirements:
▪
Sensor circuit 10 to 30V ~
▪
Tripping current 0.5 to 3 mA
(equivalent to a tripping resistance of 3 to 60 k
Ω)
▪

DANGER
Work on the pump set by unqualified personnel
Danger of death from electric shock!
▷
Always have the electrical connections installed by a trained electrician.
▷
Observe regulations IEC 30364 (DIN VDE 0100) and, for explosion-proof pump
sets, IEC 60079 (DIN VDE 0165).

Damage to the mains network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
CAUTION
Improper wiring
Damage to the power cables!
▷
Never move the power cables at temperatures below -25 °C.
▷
Never bend or crush the power cables.
▷
Never use the power cables to lift up the pump set.
CAUTION
Motor overload
Damage to the motor!
▷
Protect the motor against overloading by a thermal time-lag overload
protection device in accordance with IEC 947 and local regulations.
For electrical connection observe the wiring diagrams in the Annex and the
information for planning the control system.
The pump set is supplied complete with power cable. Always connect all marked
conductors.
DANGER
Incorrect wiring
Explosion hazard!
▷
The core ends must be connected outside of the potentially explosive
atmosphere or inside electrical equipment approved to equipment category
II2G.
DANGER
Operating an incompletely connected pump set
Explosion hazard!
Damage to the pump set!
▷
Never start up a pump set with incompletely connected power cables or non-
operational monitoring devices.
