Note
Observe all applicable national and regional regula-
tions and instructions.
◦ The protection rating IP 25 (hoseproof) can only be
ensured with a correctly tted cable grommet.
◦ The specic electrical resistance of the water must
not fall below that stated on the type plate. In a linked
water network, observe the lowest electrical water
resistance (see chapter “Specication / Application
areas / Conversion table”). Your water supply utility
will advise you of the specic electrical water resist-
ance or conductivity.
