10 Safety

Electricity safety
WARNING! Ignoring the instructions can cause physical injury or death, or
damage to the equipment.
Only qualified electricians are allowed to install
and maintain the drive!
• Never work on the drive, motor cable or motor when input power is applied. After
disconnecting the input power, always wait for 10 minutes to let the intermediate
circuit capacitors discharge before you start working on the drive, motor or motor
cable.
Always ensure by measuring with a multimeter (impedance at least 1 Mohm) that:
•
There is no voltage between the drive input phases L1, L2 and L3 and the
ground.
• There is no voltage between ter and BR and the ground.
• Do not work on the control cables when power is applied to the drive or to the
external control circuits. Externally supplied control circuits may carry dangerous
voltage even when the input power of the drive is switched off.
• Do not make any insulation or voltage withstand tests on the drive.
• Be sure the system is properly grounded before applying power. Do not apply AC
power before you ensure that all grounding instructions have been followed.
Electrical shock can cause serious or fatal injury.
Note:
Even when the motor is stopped, dangerous voltage is present at the power circuit
terminals L1, L2, L3 and U, V, W and + and BR.

General safety
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• The drive is not field repairable. Never attempt to repair a malfunctioning drive;
contact your local ABB representative or Authorized Service Centre for
replacement.
• Make sure that dust from drilling does not enter the drive during the installation.
Electrically conductive dust inside the drive may cause damage or lead to
malfunction.
• Ensure sufficient cooling.
