2.3 Safety Precautions

WARNING

UNINTENDED START

When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,

serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus

command, an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared

fault condition.

-Press [Off] on the LCP before programming parameters.

-Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended

motor start.

-Check that the drive, motor, and any driven equipment are in operational readiness.

WARNING

LACK OF SAFETY AWARENESS

This document gives important information on how to prevent injury and damage to the equipment or the system. Ignoring

them can lead to death, serious injury, or severe damage to the equipment.

-Make sure to fully understand the dangers and safety measures incurred in the application.

3.1 Safety Instructions

WARNING

DISCHARGE TIME

The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be

present even when the warning indicator lights are off.

Failure to wait the specified time after power has been removed before performing service or repair work could result in death

or serious injury.

-Stop the motor.

-Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and

DC-link connections to other drives.

-Wait for the capacitors to discharge fully before performing any service or repair work. The discharge time is specified in the

drive operating guides.

-Use a measuring device to make sure that there is no voltage, before opening the drive or performing any work on the

cables.

WARNING

BEFORE INSTALLATION/REPAIR

The operator or electrical installer is responsible for compliance with all applicable national and local safety regulations. Not

following national and local regulations may lead to personal injury.

-Disconnect all electric power, including remote disconnects, and discharge all motor start/run capacitors before servicing.

-To ensure that the power cannot be inadvertently energized, follow proper lock-out/tag-out procedures.

For more safety information, see 2 Safety and the relevant drive operating guide. Also, always observe the instructions provided by the

motor manufacturer.
