6 ACH580 Installation, Operation and Maintenance Manual
Safety instructions
• Install temporary grounding to the drive 
output terminals (T1/U, T2/V, T3/W). 
Connect the output terminals together as 
well as to the PE.
Start-up and operation:
• Make sure the motor is not run over the 
rated speed with dynamic/positive 
displacement loads.
General safety in operation
These instructions are for all personnel that 
operate the drive.
WARNING! Obey these instructions. If 
you ignore them, injury or death, or 
damage to the equipment can occur.
• Do not control the motor with the line side 
disconnect at the drive power supply; 
instead, use the control panel start and stop 
keys or commands through the I/O terminals 
of the drive.
• Give a stop command to the drive before 
you reset a fault. If you have an external 
source for the start command and the start 
is on, the drive will start immediately after 
the fault reset, unless you configure the 
drive for pulse start. See the 
ACH580 HVAC 
control program firmware manual 
(3AXD50000027537 [English]).
• Before you activate automatic fault reset 
functions of the drive control program, make 
sure that no dangerous situations can occur. 
These functions reset the drive 
automatically and continue operation after a 
fault.
Note: When the drive is not in the Hand mode, 
the Off key on the control panel will not stop the 
drive.
