* Size of the cable between the drive DC link and the brake chopper
** Size of the cable between the brake chopper and the first resistor which carries the entire braking power, see
section
Connecting the DC and resistor cables (page 46)
Note:
In order for the installation to comply with the EMC Directive, unshielded single-core cable
can only be used if it is routed inside a cabinet that efficiently suppresses radiated emissions.

SAFUR200F500
Degree of protection
The degree of protection of the brake chopper module and the SAFUR resistors is IP00 (UL
type open).
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.
