Instructions for electrical connection
WARNING
If the machine is not connected correctly to the electricity network death due to
electrocution may occur. To prevent electric shocks always use a three wire electrical
system connected to earth. For maximum protection against electric shocks use a
circuit protected with a differential cut-out switch.
WARNING
Tampering with the earthing plug in any way may result in death from electrocution. Do
not cut, remove or break the earthing plug. If the socket does not match the plug
consult a qualified electrician.
WARNING
Do not use the machine if the switch malfunctions.
HAZARD
If the machine is used with a damaged plug or power supply cable death may occur
from electrocution. If cables or plugs are worn or damaged in any way, have them
replaced by the manufacturer or the K&T technical support service or similarly qualified
person, in order to prevent risks to safety.
Cables, extensions and plugs
Only use approved cables. The maximum recommended cable length is 7m; for greater lengths use cables with a
larger cross-section.
CAUTION
Using the machine with unsuitable cable cross-sections and/or excessively long cables
may cause injury or damage to people or objects.
WARNING
The machine must never be moved using its cable and the cable must never be pulled
when disconnecting from the socket.
WARNING
Keep the cable away from sources of heat, oil and sharp edges.
WARNING
MACHINE WITH 230V∼ 50Hz SINGLE PHASE MOTOR
For machines with a 230-240V~50Hz single phase motor (Europe), a HO5VV-2x1.5 mm2 HAR-approved
power supply cable must be used along with an approved SHUKO 2P+T16A 200÷250V plug.
For non-European versions contact an authorised K&T distributor.
