5.1 Safety precautions

Danger due to electric current
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.
The programming of the equipment takes place with switched
•
on supply voltage by opened cover and voltage for change-
over Setpoint 1/2. Use power supplies which guarantee reli-
able electrical isolation of the operating voltage as per IEC/-
DIN EN 60204-1. Consider also the general requirements for
PELV circuits in accordance with IEC/DIN EN 60204-1.
Inspect electrical equipment periodically: retighten loose con-
•
nections – immediately replace damaged lines and cables.
