Technical Information
Replacement of the ZETADYN 3C frequency inverter with the ZAdyn4C frequency
inverter
Safety instructions
Danger!
It is forbidden to carry out work on electrically live parts.
In frequency inverters of the ZAdyn type, the intermediate circuit (terminals ZK+ / ZK- or +DC / -DC) are
still under voltage even after switching off.
You must wait at least three minutes.
Danger!
It is not permitted to operate the frequency inverter with the housing covers removed, as exposed live
parts are present inside the device. Failure to observe this provision can lead to serious injury.
Work on electric components may only be carried out by trained electricians or by persons instructed in
electricity under the supervision of an electrician in accordance with electrical engineering regulations.
A second person must always be present when working on energized parts or lines who disconnects in
case of emergency.
Electrical equipment must be checked regularly: Loose connections must be fixed, damaged lines or
cables must be replaced immediately. The switch cabinet and all electrical supply units must always be
kept closed. Access is only allowed to authorised persons with a key or special tool.
Dimensioning of the frame size
