�?Terminal box on top, and cable entry on right side (viewed from
driven end). Variable location of connection boxes and cable
entries as option.
�?Insulation system is designed for temperature class 155 (F). At
rated output with line-fed operation, the motors can be used in
temperature class 130 (B).
�?Self ventilated motors with radial-flow fans (cooling method IC
411 according to IEC 60034-6) as standard, forced air cool with
external separately driven fans as option.
�?FS 80 ~ 90 motor donot have eyebolt; FS 100 ~ 315 all motors
have 2 eyebolts, and FS 355 motor have one eyebolt for
transport.
Environmental
�?Degrees of motor protection IP55 (IEC 60034-5).
�?Altitude shall not exceed 1000m above sea-level (IEC 60034-1).
�?Allowed air temperature between -20 ºC and 40 ºC (IEC 60034-1).
�?Permitted relative humidity:
• -20 ºC �?T �?20 ºC�?00 %
• 20 ºC < T �?30 ºC�?5 %
• 30 ºC < T �?40 ºC�?5 %
For higher coolant temperatures and / or site altitudes higher
than 1000 m above sea level, the specified motor output must be
reduced by using the factor kHT. The results in an admissible output
(Padm) of the motor:
Padm = Prated • kHT

Foot note:
1) Order other voltages with voltage code 90 and the
corresponding Option code (see under "Option") .
2) The types of construction IM B6/7/8, IM V6 and IM V5 without
protective cover are also possible as long as no condensation
drainage holes (Order code: H03) and no stamping of these types
of construction on the rating plate are required. As standard, the
type of construction IM B3 is then stamped on the rating plate.
3) The type of construction is stamped on the rating plate. When
ordering with condensation drainage holes (order code H03),
it is absolutely necessary to specify the type of construction for
the exact position of the condensation drainage holes during
manufacture.
4) The types of construction IM V1 and IM V3 without protective
cover are also possible as long as no condensation drainage
holes (Order code: H03) and no stamping of these types of
construction on the rating plate are required. As standard, the
type of construction IM B5 is then stamped on the rating plate.
5) The types of construction IM V19 and IM V18 without protective
cover are also possible as long as no condensation drainage
holes (Order code: H03) and no stamping of these types of
construction on the rating plate are required. As standard, the
type of construction IM B14 is then stamped on the rating plate.
6) For motor with IM B5, IM V1, IM V3, IM B14, IM V18 and IM V19
construction and mounting type, the 16th digit of motor order
No. must be "4";
7) Only for FS80 ~ 160.
8) Without canopy, for protective cover with canopy needed
Option code H00.
9) Cable entry on connection box towards the non-drive.
Order No. example:
Low voltage three phase motor
4-pole, 15 kW, IM B5, 380VD/660VY 50 Hz, IP55, connection
box on top and cable entry at right side (view from DE), with
separately driven fan.
