SUPPLY CABLE
The supply cable is not delivered with the machine.
Specifications:
– Conductors with copper cores
– Stranded conductors are strongly recommended (flexible wiring) to avoid conductor breaking because
of vibration
– THE CROSS SECTION DEPENDS ON THE USED SUPPLY PROTECTION DEVICE. SEE TABLE 4.4.,
FOR THE MINIMAL CROSS SECTION
– As short as possible, directly from the supply protection device to the machine without branching off.
– No plug or extension cords : The machine is intended to be permanently connected to the electrical network
Connection:
– Insert the cable through the hole in the on the rear panel, insure a strain relief (turnbuckle) is used so that the supply
cable can not move.
– Strip the conductor ends according figure 4.4.C.
– The protective conductor must be longer so that when the cable is pulled out accidentally, this conductor
is disconnected the last one!
– With stranded conductors, use „wire end tubes“ with an insulated sleeve (6) for L1/U, (L2/V), (L3/W), (N)
conductors. Make sure there can not be accidental contact, since the supply cable stays under voltage even when
the main switch is off.
– Crimp a ring terminal (eyelet) to the protection conductor for good fixation to the PE terminal.
– Connect the supply cable conductors to the terminals (main switch (1)) marked with L1/U, (L2/V), (L3/W), (N),
and the terminal (copper screw) marked with PE, see figure 4.4.D.
– Provide a sag in the cable, in front of the cable strain relief. This will avoid ingress of condensed water
into the machine, see figure 4.4.D.
MACHINE WITH TILTING
– The selected power supply cable, figure 4.4.B., pos.1 needs to come from above and vertical directed
downwards in line with the supply cable entry.
– The cable needs to be on ± 30cm backwards away from the backside, pos.2 of the machine, when in tilting base,
pos.3 rest position. Just before entry, a sag of min 5 and max 15 cm must be provided.
– From the point of entry, up to 1 m high, no fixation of the supply cable is allowed.
