Electrical Safety In Installation, Start-Up And Maintenance - ABB ACH580 Series User Manual

ACH580 Installation, Operation and Maintenance Manual
• Before you connect voltage to the drive,
make sure that the drive covers are on.
Keep the covers on during the operation.
• Before you adjust the drive operation limits,
make sure that the motor and all driven
equipment can operate throughout the set
operation limits.
• Before you activate the automatic fault reset
or automatic restart 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 or supply
break. If these functions are activated, the
installation must be clearly marked as
defined in IEC/EN 61800-5-1, subclause
6.5.3, for example, "THIS MACHINE
STARTS AUTOMATICALLY".
• The maximum number of drive power-ups is
five in ten minutes. Too frequent power-ups
can damage the charging circuit of the DC
capacitors.
• If you have connected safety circuits to the
drive (for example, emergency stop and
Safe torque off), validate them at the start
up. For the validation of the Safe torque off,
see ACH580 HVAC control program
firmware manual (3AXD50000027537
[English]). For the validation of other safety
circuits, see the instructions provided with
them.
Note:
• If you select an external source for start
command and it is on, and the start
command is level-triggered, the drive will
start immediately after fault reset. See
parameters 20.02 Ext1 start trigger type and
20.07 Ext2 start trigger type in ACH580
HVAC control program firmware manual
(3AXD50000027537 [English]).
• When the control location is not set to Local
(text Hand is not shown on the top row of the
panel and parameter 19.19 Off mode
disable has value Off button disabled), the
stop key on the control panel will not stop
the drive.
• Frames R1...R5: Do not attempt to repair a
malfunctioning drive; contact your local
representative for replacement or repair by
authorized persons.
• Frames R6...R9: Can be repaired by
authorized persons.

Precautions before electrical work
These warnings are for all personnel who do
work on the drive, motor cable or motor.
WARNING! Frames R1 ... R9: Obey
these instructions. If you ignore them,
injury or death, or damage to the equipment
can occur. If you are not a qualified electrical
professional, do not do electrical installation or
maintenance work. Go through these steps
before you begin any installation or
maintenance work.
1. Clearly identify the work location.
2. Disconnect all possible voltage sources.
Lock and tag.
• Open the main disconnector at the power
supply of the drive.
• Make sure that reconnection is not
possible.
• Disconnect any external power sources
from the control circuits.
• After you disconnect the drive, always
wait for 5 minutes to let the intermediate
circuit capacitors discharge before you
continue.
3. Protect any other energized parts in the
work location against contact.
4. Take special precautions when close to bare
conductors.
5. Measure that the installation is
de-energized.
• Use a multimeter with an impedance of at
least 1 Mohm.
