Safety

What this chapter contains

The chapter contains the safety instructions which you must follow when installing,

operating and servicing the drive. If ignored, physical injury or death may follow, or

damage may occur to the drive, motor or driven equipment. Read the safety

instructions before you work on the drive.

Use of warning symbols

There are two types of safety warnings throughout this manual:

Danger; electricity warns of high voltage which can cause physical

injury and/or damage to the equipment.

General danger warns about conditions, other than those caused by

electricity, which can result in physical injury and/or damage to the

equipment.

Installation and maintenance work

These warnings are intended for all who work on the drive, motor cable or motor.

WARNING! Ignoring the following 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 5 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:

1. There is no voltage between the drive input phases U1, V1 and W1 and the

ground.

2. There is no voltage between terminals BRK+ and BRK- 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.

Note:

¤ Even when the motor is stopped, dangerous voltage is present at the power

circuit terminals U1, V1, W1 and U2, V2, W2 and BRK+ and BRK-.
