Power supply:
Check if sufficient power is available on the site. The machine must be
connected to a 380 – 500 V 3-phase supply. The power pack has a 32
Amp 5-pin Euro standard receptacle. At 400 V a 32 Amp delay fuse will
be enough to run the power pack and motor at their maximum rated
output. We recommend to use a 40 Amp fuse if possible. Even 16 Amp
(25 Amp for the 27 kW HF-motor) delay fuses can be used but then the
power output must be reduced by turning the feed rate knob on the
remote control to 65%.
Safety precautions
on the site:
Check with the foreman responsible that all necessary precautions have
been performed before commencing work. Await the approval of the
safety precautions and mounting position of the machine from a
responsible person before work is commenced.
Warning! If there is a possibility that concrete blocks may fall down causing injury or
damage to persons or property then they must be secured before starting work. The risk
area must be roped off and a responsible person left in charge, in a safe place, to prevent
entry of unauthorised persons.
