equipment may be stored, but it is
not suitable for use outdoors in the rain,
unless it is protected. Suitable for use in
high-risk environments.
Geschikt voor gevaarlijke omgevingen.
H Isolation Class.
AF Aircooling with fan.

2.4 THERMAL PROTECTION

This inverter is protected by a thermostat. When the
thermostat is tripped, the machine stops delivering
current but the fan continues to run. The yellow led
(19) lights to indicate when it is tripped. Do not shut
off the welding machine until the led has gone off.

2.5 MOTOR-DRIVEN GENERATORS

These must have a power equal to or greater than 6
kVA, and must not deliver a voltage greater than 265 V.

3. INSTALLATION

This must be carried out by skilled personnel. All
connections must be carried out according to current
regulations, and in full observance of safety laws (CEI
reglement 26-10 – CENELEC HD 427).
- Make sure that the supply voltage matches the
voltage indicated on the specifications plate.
- When mounting a plug, make sure it has an
adequete capacity, and that the yellow/green
conductor of the power supply cable is connected to
the earth pin.
WARNING! Extension cords of up to 30 m must have a
crosssection of at least 2.5 mm².
