Introduction to the manual 7 Introduction to the manual Contents of this chapter This chapter contains general information of the manual, a list of related manuals, and a list of terms and abbreviations. Applicability This manual is applicable with single drive cabinets and modules. Target audience This manual is intended for people who plan electrical installation of the drive.
The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the drive may experience problems that the warranty does not cover.
Examining the compatibility of the motor and drive Use asynchronous AC induction motors, permanent magnet synchronous motors, AC induction servomotors or ABB synchronous reluctance motors (SynRM motors) with the drive. Select the motor size and drive type from the rating table on basis of the AC line voltage and motor load.
Electrical planning guidelines 13 Note: • Consult the motor manufacturer before using a motor whose nominal voltage differs from the AC line voltage connected to the drive input. • The voltage peaks at the motor terminals are relative to the supply voltage of the drive, not the drive output voltage.

The rated output power of high-output motors is higher than what is stated for the particular frame size in EN 50347 (2001). If you plan to use a non-ABB high-output motor or an IP23 motor, consider these additional requirements for protecting the motor insulation and bearings in drive systems: •...

Additional note for sine filters A sine filter also protects the motor insulation system. The peak phase-to-phase voltage with a sine filter is approximately 1.5 · U . Check the availability of the sine filter from ABB. Selecting the power cables ■...
20 Electrical planning guidelines To comply with the EMC requirements of the CE mark, use one of the preferred cable types. Preferred power cable types (page 21). Symmetrical shielded cable reduces electromagnetic emission of the whole drive system as well as the stress on motor insulation, bearing currents and wear. Metal conduit reduces electromagnetic emission of the whole drive system.
Electrical planning guidelines 21 ■ Power cable types Preferred power cable types This section presents the preferred cable types. Make sure that the selected cable type also complies with local/state/country electrical codes. Cable type Use as input power cabling Use as motor cabling Symmetrical shielded (or armored) cable with three phase conductors and concentric PE conductor as...
■ Additional guidelines, North America ABB recommends the use of conduit for power wiring to the drive and between the drive and the motor(s). Due to the variety of application needs, metallic and non-metallic conduit can be used. ABB prefers the use of metallic conduit.
Electrical planning guidelines 23 Wiring method Notes Free air Prefer symmetrical shielded VFD cable. Enclosures, air handlers, etc. Allowed internally in enclosures when in accordance with UL. 1) Metallic conduit may be used as an additional ground path, provided this path is a solid path capable of handling ground currents.
■ Relay cable type The cable type with braided metallic shield (for example ÖLFLEX by LAPPKABEL, Germany) has been tested and approved by ABB. ■ Control panel to drive cable Use EIA-485 with male RJ-45 connector, cable type Cat 5e or better. The maximum permitted length of the cable is 100 m (328 ft).

Name Code FSO-12 safety functions module user's manual 3AXD50000015612 FSO-21 safety functions module user's manual 3AXD50000015614 ■ Modules You can order a safety function module from ABB. The cabinet builder can use the module for implementing various safety functions.
Using a safety switch between the drive and the motor ABB recommends to install a safety switch between the permanent magnet motor and the drive output. The switch is needed to isolate the motor during any maintenance work on the drive.
IEC/EN 61800-5-1, subclause 6.5.3, for example, “THIS MACHINE STARTS AUTOMATICALLY”. Bypass connection is available as a factory-installed option for some cabinet-installed drive types. Consult ABB for more information. WARNING! Never connect the drive output to the electrical power network. The connection may damage the drive.

34 Electrical planning guidelines The relay contacts on the drive control unit are protected with varistors (250 V) against overvoltage peaks. In spite of this, it is highly recommended that inductive loads are equipped with noise attenuating circuits (varistors, RC filters [AC] or diodes [DC]) to minimize the EMC emission at switch-off.
