TOSHIBA UTNH23A input signal module

Placing Install the BSFC unit in a heated indoor environment. Make sure that the temperature meets the requirement given in the technical data. Also make sure that the ambient conditions meet the requirements of the hardware manual of the inverter modules. Do not install the BSFC unit far from the inverters. The length of the fiber optic cable(s) between the unit and the inverter(s) must not be more than 4 m (13.1 ft). WARNING! No condensation is permitted. There are connectors that are connected to drive main circuit potential. WARNING! Protect the BSFC unit against accidental contact. There are connectors that are connected to drive main circuit potential.

Limitation of liability

 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.Use a grounding wristband when you handle printed circuit boards. Do not touch the boards unnecessarily. The boards contain components sensitive to electrostatic discharge.

 List of components needed in power supply circuit 

• DC switch-disconnector kit (DC switch-disconnector, BSFC unit, charging switch, charging resistors)1) 

• DC fuses for inverter 

• Charging circuit fuses 

• Fiber optic cables for BSFC – inverter connection (one pair for each inverter) 

• Main DC supply cables/busbars 

• Charging circuit cables, BSFC power supply cables, DC switch-disconnector control cables. 1) Only available from ABB. Make sure that all components meet the ABB specifications. For the charging circuit wire specification, see chapter Circuit diagrams (page 25). Always use cables recommended by ABB or equivalent. The cables are connected to the drive main circuit.
