Electrical Connection; Cleaning, Maintenance And Storage - Scheppach HC20Si Twin Translation Of Original Instruction Manual

• Before you use the machine, make sure that the
mains voltage is the same as the operating voltage
(see the rating plate).
• Long supply cables, extensions, cable reels etc.
cause a drop in voltage and can impede motor
start-up.
• At low temperatures below +5°C, sluggishness
may make starting difficult or impossible.
8.3 ON/OFF switch (Fig. 2)
• To switch on the compressor, press the button (8)
on position I.
• To switch off the compressor, press the button (8)
on position 0.
8.4 Setting the pressure (Fig. 2)
• Use the pressure regulator (11) to set the pressure
on the pressure gauge (12).
• The set pressure can be drawn from the quick lock
coupling (13).
• The vessel pressure can be read off the pressure
gauge (10).
• The vessel pressure is drawn from the quick lock
coupling (13).
8.5 Setting the pressure switch (Fig. 1)
• The pressure switch (14) is set at the factory.
Cut in pressure approx. 8 Bar
Cut-out pressure approx. 10 Bar.
8.6 Thermal protector
The thermal protector is built into the device.
If the thermal protector has tripped, proceed as fol-
lows:
• Pull out the mains plug.
• Wait about two to three minutes.
• Plug the device in again.
• If the device does not start, repeat the process.
• If the device does not start again, switch the device
off and on again using the on/off switch (8).
• If you have carried out all of the steps above and the
device still does not work, contact our service team.

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.
When working with spray attachments and during
temporary use outdoors, the device must be connect-
ed to a residual current circuit breaker with a trigger
current of 30 mA or less.

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.
AC motor
• The mains voltage must be 230 V~
• Extension cables up to 25 m long must have a
cross-section of 1.5 mm
Connections and repairs of electrical equipment may
only be carried out by an electrician.
Please provide the following information in the event
of any enquiries:
• Type of current for the motor
• Machine data - type plate
• Machine data - type plate
