2.7 Electric work
2.7.1 Carrying out electric work safely
Observe the following information to carry out electric work safely during installation
and maintenance:
• Electric work may only be carried out by electrically skilled persons.
• Always adhere to the 5 safety rules for working on electrical components:
– Disconnect
– Secure the drive against restart
– Check that no voltage is applied
– Ground and short-circuit it
– Cover or safeguard neighboring live parts
• When the device is switched on, dangerous voltages are present at all power con-
nections as well as at any connected cables and terminals. This also applies even
when the product is inhibited and the motor is at standstill.
2.7.2 Electrical connection
Exceeding the stated tolerances in EN 60034-1 (VDE 0530, part 1) – voltage ± 5%,
frequency ± 2%, curve shape, symmetry – increases the heating and influences elec-
tromagnetic compatibility. Also adhere to standards DIN IEC 60364 and EN 50110.
Observe other applicable national regulations, such as DIN VDE 0105 for Germany.
In addition to the generally applicable installation regulations for low-voltage equip-
ment, it is also necessary to comply with the special regulations for setting up elec-
trical machinery in potentially explosive atmospheres (operating safety regulations in
Germany: EN 60079‑14 and system-specific regulations).
Observe the wiring information and differing data on the nameplate as well as the
provided wiring diagram.
The connection must be a permanently safe electrical connection (no protruding wire
ends). Use the corresponding cable-end equipment. Establish a safe PE connection.
When the motor is connected, the distances to non-insulated and live parts must not
be shorter than the minimum values. Adhere to the national specifications. According
to the standards in the table, the minimum distances must not be shorter than the fol-
lowing values:

The terminal box must be free from foreign objects, dirt and humidity. Unused cable
entry openings and the connection box itself must be sealed so that they are dust- and
water-proof.
Secure the key(s) for the test run without output elements.
When operating low-voltage machines with brakes, check that the brake is functioning
properly before startup.
