Additional Instructions And Notes - ABB ACS880-07 Hardware Manual

L1, L2, L3
•
Make sure that the voltage between the drive module UDC+ and UDC- terminals
and the grounding (PE) busbar is close to 0 V.
6. Install temporary grounding as required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation work.

Additional instructions and notes


WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•
If you are not a qualified electrician, do not do installation or maintenance work.
•
Do not install a drive with EMC filter option +E200 or +E202 on an ungrounded power
system or a high resistance-grounded (over 30 ohms) power system.
•
Do not connect the drive to a voltage higher than what is on the type designation label.
If you do, the brake chopper starts to operate which causes the overheating of the
brake resistor (if present). Overvoltage can also cause the motor to rush to its
maximum speed.
•
We do not recommend that you secure the cabinet by arc welding. If you have to, obey
the instructions in section
•
Do not do insulation or voltage withstand tests on the drive or drive modules.
Note:
•
The motor cable terminals of the drive are at a dangerous voltage when the input
power is on, regardless of whether the motor is running or not.
•
The DC bus and brake resistor terminals (UDC+, UDC-, R+ and R-) are at a
dangerous voltage.
•
External wiring can supply dangerous voltages to the terminals of relay outputs
(XRO1, XRO2 and XRO3).
•
The Safe torque off function does not remove the voltage from the main and auxiliary
circuits. The function is not effective against deliberate sabotage or misuse.
