5.1
Safety precautions
Work on electric components may only be carried out by trained electricians or by persons instructed
in electricity under the supervision of an electrician in accordance with electrical engineering regula-
tions.
Electrical equipment must be checked regularly: loose connections are to be re-tightened and
damaged cables must be replaced immediately.
Always keep switch cabinets and all electrical supply facilities locked. Access is only allowed for
authorized persons using a key or special tool.
Never clean electrical equipment with water or similar liquids.
5.2
EMC directive
Compliance with the EMC directive 2014/30/UE only applies to this product if frequency inverters
are
used and are installed in line with the
associated operating instructions and are EMC-compatible. If this
product is improperly integrated into
a system or is combined and operated with non-EMC compatible
components, the manufacturer or
operator of the complete system is solely responsible for compliance
with the EMC directive 2014/30/UE. In detail, connecting devices that are EMC rules compliant
doesn’t mean necessarily that the whole system will be EMC compliant.
5.3
Motor
The motor cable for the elevator machine is available as an option.
The elevator machine cannot be connected to the supply line without a frequency inverter
in between. Connecting the machine directly to the supply line can destroy the motor.
5.3.1
Cable cross section
The cable cross-section must be specified dependent on the motor current and the ambient conditions
(e.g. temperature, wiring method) in accordance with IEC 204-1.
5.3.2
Type of cable
Always use shielded cables for the motor connections! Both rigid and flexible lines can be installed.
The use of wire-end sleeves is recommended for flexible lines.
Rated voltage U0 / U: 450 / 750 V AC
5.3.3
Cable length
The maximum cable length is 25 m. With a motor line > 25 m compliance with EN 12015 (Electro-
magnetic Compatibility - Interference emissions) and EN 12016 (Electromagnetic Compatibility -
Interference immunity) can no longer be guaranteed.
