8.8 Setting the pressure switch (Fig. 1)
• The pressure switch (2) is set at the factory.
Cut-in pressure approx. 6 bar
Cut-out pressure approx. 8 bar.
8.9 Overload switch (Fig. 14)
The motor is fitted with an overload switch (18). If the
compressor overloads, the overload switch switches
off the equipment automatically to protect the com-
pressor from overheating. If the overload switch trig-
gers, switch off the compressor using the ON/ OFF
switch (16) and wait until the compressor cools down.
Then press the overload switch (18) and restart the
compressor.
9. Electrical connection
The electrical motor installed is connected and
ready for operation. The connection complies
with the applicable VDE and DIN provisions.
The customer's mains connection as well as
the extension cable used must also comply with
these regulations.
Important information
In the event of an overloading the motor will switch
itself off. After a cool-down period (time varies) the
motor can be switched back on again.
Damaged electrical connection cable
The insulation on electrical connection cables is of-
ten damaged.
This may have the following causes:
• Passage points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been im-
properly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the
wall outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Make sure that the connection cable does
not hang on the power network during the inspection.
Electrical connection cables must comply with the
applicable VDE and DIN provisions. Only use con-
nection cables with the marking „H05VV-F".
The printing of the type designation on the connec-
tion cable is mandatory.
