Where no explosion protection is stipulated for
the pumping of foul wastewater at the instal

lation location, UAK pumps may also be used.
Electrical connection
By using our controls, you can be sure that the
requirements of the EU type-testing certificate
are met.
Only qualified electricians may carry
out electrical works to the pump or
the controls.
The standards applicable in each case (e.g. EN),
the country-specific regulations (e.g. VDE in
Germany), and the regulations of the local sup
-
ply network operator must be observed.
ATTENTION!
Never lay the end of cables in wa

rent
The alternating current pumps must not be
used without a control unit.
MultiCut pumps in alternating current versions
are protected by 2 winding thermostats and a
motor contact switch in the AD 12 Ex ME con

trol unit. The two operating condensers in the
control unit must be dimensioned according to
the measurements indicated in the Type Exami

nation Certificate.

plug connection (Y) and the built-in motor. The
new crimp connection must be professionally

Only slow-blow fuses or automatic fuses with C

for the pump. Necessary fuse protection for di

The pump must be protected via an overload

If the protective device has been triggered, the
cause of the malfunction must be eliminated
before switching on again.
Potential equalisation
To comply with EN 60079-14 and EN 1127-1,
an additional equipotential bonding must be
installed for facilities with protective earth con
-
ductors in TN/TT networks in areas subject to
explosion hazards. In Germany, for example,
the design must be in accordance with VDE
0100, Part 540 (Association of German Electri

cal Engineers).
No additional potential equalisation is required
on site for JUNG PUMPEN concrete or plastic
chambers in explosion zones 1 and 2 (state

Agency) in March 2008).
