ABB ACS580MV - SBU Commissioning; Safety; Software Requirements; Inspection of Installation

Option 105
• Confirm the MCB is open, switch the S7804 to ‘Remote mode’ or ‘Local mode’, set to
the ‘Bypass mode’, monitor and run the motor by overriding system.
SBU Commissioning
Synchronized bypass unit (SBU) is an option and used when motors need to be
synchronized to main. According to the number of the motors, synchronized bypass
function can be divided to two types, single motor mode and multi motor mode. In multi
motor mode, marshalling unit (MAU) is necessary. Commissioning for SBU and MAU must
be carried out by engineer who has been certified with “Expert”.
 Safety
Obey safety instructions when you install, operate or do maintenance on the bypass -
drive system. If you ignore the safety instructions, injury, death or damage can occur.
Safety instructions are used to highlight a potential hazard when working on the
equipment. Safety instructions must be strictly followed! Non-compliance can jeopardize
the safety of personnel, the equipment and the environment. Refer to Safety instructions.
 Software requirements
The Latest software is recommended.
 Inspection of installation
Complete installation checklist before commissioning can take place.
See ACS580MV Hardware Manual (2UBB004520) for other information of installation.
Notice:
1. Mains and converter output PT should be same type. Single phase PT is
recommended. If it’s three phase PT and on second side phase to phase voltage
signal is used, below earthing point should be removed (bridge between -X117:2&3,
and –X118:2&3).
2. PT1.1 and PT2.1 has to measure the voltage between the same phases (Phase U/V
recommended), also PT1.2 if it’s available.
NOTICE If the drive integrated with MBU cabinet, pay more attention to the ‘Bypass
mode’, the rated input current is based on the motor current.In some situation, the
setting of protection relay should be modified.
