Inquiries Address any inquiries about the product to the local ABB representative, quoting the type code and the serial number of the unit. If the local ABB representative cannot be contacted, address inquiries to the manufacturing facility. About this manual...
ASFC unit overview Frame size R8i inverter modules are connected to the drive DC bus through a switch fuse (type OESL by ABB). The installation is equipped with a Switch Fuse Controller Unit (ASFC) which controls the inverter power switch-on and power switch-off. The unit also...
ASFC Settings Power supply The jumper settings at connectors X7 and X8 define the voltage level as follows. Voltage 230 VAC 115 VAC Charging circuit monitoring For each inverter module in the system (one to three) there is a charging current monitoring on the ASFC unit.
ASFC LEDs Name Colour Indication Illuminates when INV1 STAT Yellow Charging of inverter 1 is Charging monitoring of Inverter 1 is enabled (switch S1 = EN) in progress, or Inverter 1 and charging current is above 0.7 A. is not in use Switch fuse main contacts are open (auxiliary contact connected to connector X4 is open).
Connections of the inverter power supply Description Drive DC bus Switch fuse 2a: primary contacts - main contacts 1-2 and 3-4 - auxiliary contacts 13-14 to 33-34 2b: secondary contacts - main contacts 1-2 and 3-4 for charging circuit - auxiliary contacts 13-14 to 71-72 for charging circuit 2c: solenoid that operates the locking mechanism of the primary contacts Inverter Charging resistors...
Inverter power switch-on sequence The terms and designations used in the table below refer to the diagram in section Connections of the inverter power supply. Operation What happens User turns switch fuse Secondary contacts of switch fuse operate. Locking mechanism handle to 1 (On) keeps spring operated primary contacts open.
Miscellaneous Details of the locking solenoid control The switch fuse locking is released by the locking solenoid when: • Switch fuse handle in 1 (on) position. (ASFC monitors an auxiliary contact.) • DC voltage of all inverter modules monitored by the ASFC unit exceed 80% of the nominal value.
Cable selection See ACS800-104 Inverter Module Hardware Manual (3AFE64809032 [English]). Always follow the specification given by ABB. The cables are connected to drive main circuit potential. Protecting against contact Protect the ASFC unit against accidental contact. There are connectors that are connected to drive main circuit potential.
