2.10.1 Electrical connection
CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
Please check whether the type of current, voltage and protection fuse correspond to the values
specified. A protective earth conductor connection must be available.
Min. terminal cross-section per phase and grounding: 2mm
2
Electric connected load: 5.935 KVA
Permissible voltage fluctuations in normal operation: ± 10% Volt
Permitted frequency fluctuations: ± 1Hz (50/60 Hz)
Permitted instantaneous shutdown period: 10 ms
Permitted voltage pulse: 200% or less than the actual value of the mains voltage (effective
value): 1.5 ms 1.5 ms
Permitted unevenness of a phase: 5% or less
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly.
The neutral conductor (N) of its power supply is not connected.
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 automatic spindle sleeve moves in the wrong direction and can damage
components on reaching the end stop.
The guarantee will become null and void if the machine is connected incorrectly.

First commissioning
The machine may only be commissioned after proper installation.
ATTENTION!
Before commissioning the machine, all bolts, fastenings and protections must be
checked and retightened as necessary!
WARNING!
The use of improper tool holders or their operation at inadmissible speeds constitutes a
hazard.
Only use the tool holders (e.g. drill chuck) which were delivered with the machine or
which are offered as optional equipment by OPTIMUM.
Only use tool holders in the intended admissible speed range.
Tool holders may only be modified in compliance with the recommendation of OPTI-
MUM or of the manufacturer of the clamping devices.
