DANGER! Risk of fatal injury!
Improper electrical connections can lead to fatal electrical shocks.
• Have the electrical connection established by an electrician approved by the local elec-
tricity supplier only and in accordance with local regulations.
• Observe the installation and operating instructions of the switchgear and the accesso-
ries!
• The current type and voltage of the mains connection must correspond to the specifica-
tions on the name plate.
• Mains side fuse protection:
• DrainLift M2/8 (1~): 16 A, slow-blow
• DrainLift M2/8 (3~)>: 16 A, slow-blow
NOTE: To increase operating safety, it is essential that a circuit breaker (which disconnects
all power leads) with K characteristic is used.
• Earth the system according to regulations.
• Lay the connecting cable in accordance with the applicable standards/regulations and the
prescribed wire connection.
• It is urgently recommended to use a residual-current-operated protection switch Û 30 mA
according to the valid local regulations.
• The switchgear and alarm must be installed in dry rooms which are overflow-proof. The
national regulations are to be observed when positioning [in Germany: VDE 0100].
• Make sure that the separate supply of the alarm switchgear matches the name plate data.
Connect the alarm switchgear.
• For three-phase versions, apply a clockwise rotating field.
• When connecting, the technical connection conditions of the local electricity supply com-
panies are to be observed.
