Safety 

WARNING!

 All electrical installation and maintenance work on the drive 

should be carried out by qualified electricians only.

WARNING!

 The drive and adjoining equipment must be properly 

grounded.

WARNING!

 Do not attempt any work on a powered drive. After 

switching off the mains, always allow the intermediate circuit capacitors 
5 minutes to discharge before working on the drive, the motor or the 
motor cable. It is good practice to check (with a voltage indicating 
instrument) that the drive is in fact discharged before beginning work.

WARNING!

 The motor cable terminals of the drive are at a dangerously 

high voltage when mains power is applied, regardless of motor 
operation. 

WARNING!

 There can be dangerous voltages inside the drive from 

external control circuits even when the drive mains power is shut off. 
Exercise appropriate care when working on the unit. Neglecting these 
instructions can cause physical injury or death.

Use of Warnings and Notes

There are two types of safety instructions throughout this manual:

•  Notes draw attention to a particular condition or fact, or give 

information on a subject. 

•  Warnings caution you about conditions which can result in serious 

injury or death and/or damage to the equipment. They also tell you 
how to avoid the danger. The warning symbols are used as follows:

Dangerous voltage warning

 warns of high voltage which can cause 

physical injury and/or damage to the equipment.
