Safety instructions
This technical information sheet contains additional information on the ZAdyn4C operating
instructions (R-TBA12_01). Observe the ZAdyn4C operating instructions.
Danger!
It is forbidden to carry out work on electrically live parts.
In frequency inverters of the ZETADYN and 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 regula-
tions.
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 are to be re-tightened and
damaged lines or cables must be replaced immediately. The switch cabinet and all electrical supply
units must be kept locked at all times. Access is only allowed to authorised persons with a key or
special tool.
