Optical components

The specifications of the optic cable are as follows:
• Storage temperature: -55 ... +85 °C
• Installation temperature: -20 ... +70 °C
• Maximum short-term tensile force: 50 N
• Minimum short-term bend radius: 25 mm
• Minimum long-term bend radius: 35 mm
• Maximum long-term tensile load: 1 N
• Flexing: Max. 1000 cycles
ABB drive products in general utilize 5 and 10 MBd (megabaud) optical components from
Avago Technologies' Versatile Link range. Note that the optical component type is not
directly related to the actual communication speed.
Note:
The optical components (transmitter and receiver) on a fiber optic link must be of the same
type.
Plastic optical fiber (POF) cables can be used with both 5 MBd and 10 MBd optical
components. 10 MBd components also enable the use of Hard Clad Silica (HCS®) cables,
which allow longer connection distances thanks to their lower attenuation. HCS® cables
cannot be used with 5 MBd optical components.
The maximum lengths of fiber optic links for POF and HCS® cables are 20 and 200 meters
respectively.

Protection classes

Degrees of protection
(IEC/EN 60529)
Enclosure types (UL50)
Overvoltage category

Protective class

500 m (1640 ft).
Note:
Longer cables cause a motor voltage decrease which limits the available motor
power. The decrease depends on the motor cable length and characteristics.
Contact ABB for more information.
Note:
With motor cables longer than 150 m (492 ft) the EMC Directive requirements may
not be fulfilled.
IP42 (standard), IP54 (option +B055)
UL Type 1 (standard), UL Type 12 (option +B055). For indoor use only.
III, except for auxiliary power connections (fan, control, heating, lighting, cooling
unit pump etc) which are category II.
