3.5.1
Warming up the machine
ATTENTION!
If the drilling machine and in particular the drilling spindle is immediately operated at
maximum load when it is cold it may result in damages.
If the machine is cold, e.g. directly after having transported the machine, it should be warmed
up at a spindle speed of only 500 1/min for the first 30 minutes.
3.6
Electrical connection
3.6.1
DQ 14 ; DQ 18 ; DQ22 - 230V protective contact plug
CAUTION!
Position the power lead for the machine in such a manner that people cannot trip over it.
3.6.2
DQ 22 - 400V CEE plug
CAUTION!
Position the power lead for the machine in such a manner that people cannot trip over it.
ATTENTION!
Imperatively make sure that all 3 phases ( L1, L2, L3) are correctly connected.
Most motor defects result of wrong connections. For instance if a motor phase is not
correctly clamped or connected to the neutral conductor (N)
.
Effects may be as follows:
The motor is getting hot very rapidly.
Increased motor noises.
The motor has no power.
ATTENTION!
Make sure that the direction of rotation of the drive motor is correct. The switch position
of the rotation selector switch for right-handed rotation (R) has to turn the drill spindle
clockwise. If necessary, exchange two phase connections. The guarantee will become
null and void if the machine is connected incorrectly.
