1.2. Operating Safety
The terminals on the rear panel of the manager
may carry dangerous voltages, even if the auxiliary
voltage is switched off. A live current transformer
secondary circuit must not be opened.
Disconnecting a live circuit may cause dangerous
voltages! Any operational measures must be carried
out according to national and local handling
directives and instructions.
Carefully read through all operation instructions before any
operational measures are carried out.
