Operating safety
The terminals on the rear panel of the relay may
carry dangerous voltages, although 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 measure must be carried
out according to national and local handling
directives and instructions.
Carefully read through the relay operation instructions before
any relay operational measures are carried out.
