Lenze low-voltage machinery
5. Electrical connection
All operations must be carried out only by qualified and skilled personnel when the low-voltage machine is at standstill
and when the machine is de-energized and protected against unintentional restart. This also applies to auxiliary
circuits (e.g. brake, encoder, separate fan).
Check safe isolation from the supply!
If the tolerances in EN 60034-1; IEC 34 (VDE 0530-1) - voltage ±5 %, frequency ±2 %, waveform, symmetry - are
exceeded, more heat will be generated and the electromagnetic compatibility will be influenced.
Observe the indications on the nameplate, operating notes, and the connection diagram in the terminal box.
The connection must ensure a continuous and safe electrical supply (no loose wire ends); use appropriate cable
terminals. The connection to the PE conductor must be safe. The plug-in connector must be screwed up tightly (to
stop).
The clearances between bare, live parts and earth must not fall below: 8 mm at V
≤ 1000 V.

The terminal box must be clean and dry; foreign particles, dirt and moisture affect operation. All unused cable entries
and the box itself must be sealed against dust and water. For the trial run without output elements, lock the key. Check
brake operation before the commissioning of low-voltage machines with brakes.

is activated. If deviations from normal operation occur, e.g. increased temperature, noise, vibration, find the cause
and, if necessary, contact the manufacturer. Switch-off the machine in problematic situations.
If the drive is exposed to dirt, clean it regularly.
Do not switch-off the protection devices, not even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary, limit the maximum current. Connect the
function blocks to the option switch-off after several seconds of operation at I > I
Shaft seals and bearings have a limited service life.
Regrease the bearings using the relubrication facility while the low-voltage machine is running. Observe the
saponification number. If the grease drain hole is sealed with a plug (IP54 drive end; IP23 drive end and non-drive
end), remove the plug before commissioning. Seal the bore holes with grease. Replace the prelubricated bearings
(2Z-bearings) after approx. 10.000 h - 20.000 h, at the latest however after 3 - 4 years. Observe the manufacturer's
instructions.
