9. Electrical Connections

i
Important!
Switch-on processes generate brief voltage
reductions. If power supply conditions are
unsatisfactory, other units may be impaired.
If there is a power supply impedance of less
than 0.15 ohm at the connection point, there
should be no faults.
The electrical installation should only be
carried out by a qualified specialist. The
details given in the section "Technical
Specifications" should be taken into
consideration.
All components, cables and devices that
carry electrical current, and are within the
immediate vicinity of where work takes
place, must be in perfect condition and
splash-proof.
A lockable master switch with which the
stationary high-pressure cleaner can be
switched off must be mounted in a safe
and easily accessible location.
