5 Electrical installation
5.1 Safety precautions
Mounting, electrical connection and commissioning are only to be performed by trained service
personnel. Adhere to all machinery-related requirements and speci fi cations supplied by the system
manufacturer or machine builder.
5.2 EMC directive
The adherence to the EMC Directive 2004/108/EC only pertains to this product if controllers tested
and recommended by ZIEHL-ABEGG SE are used, which have been installed in accordance with the
corresponding controller description and in line with the EMC. If the product is integrated unprofes-
sionally into a system or complemented by and operated with components (e. g. regulators and
controllers) which have not been recommended, the operator of the complete system alone shall be
responsible for adhering to the EMC Directive 2004/108/EC.
5.3 Motor connection
CAUTION!
" The drive must not be connected to the mains supply without a controller!
" The motor is permitted to be used at frequency inverters with a maximum DC-link voltage
of < 750 V DC!
" A screened motor cable has to be used. The screen has to be connected on both ends.
The maximum motor cable length is 25 m.
" There is a wiring diagram in the motor junction box which shows how to connect the motor and
the PTC thermistor.
" The motor is protected by PTC-resistors. The connection has to be made through a PTC resistor
controller unit!
" Make sure that the motor contactors are switched load-free on the control side. The contactor
contacts could be damaged when switching under load, especially at rpm 0. Therefore the
controller enable should always be switched off before or together with the main con-
tactors.
Danger!
" This connection must be made by a specialist according to the pertinent safety regulations.
" The pertinent installation and operating regulations as well as the normal national and
international regulations must be observed.
" See the data on the rating plate!
" See the circuit!
Information
" Adapt the power cable cross sections to the reference current value.
" Provide strain relief for the connecting leads.
" Always connect the protective earth according to DIN VDE 0100 to the marked PE terminal.
" Use the original seal for connecting the junction box.
" Seal unnecessary openings dust and water tight.
CAUTION!
Caution!
" No voltage greater than 2.5 V may be applied to the PTC thermistor!
" Damp windings can lead to creep currents, sparkovers and disruptive discharges. The insulation
resistance of the stator winding must be at least 1.5 megaohms in 220 V - 1000 V motors,
measured at a winding temperature of 20 ° C. The winding must be dried at lower values.
