■ 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 ~ 355 all motors
have 2 eyebolts.
■ 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：100 %
• 20 ºC < T ¢ 30 ºC：95 %
• 30 ºC < T ¢ 40 ºC：55 %
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
