*) For safety-relevant characteristics and further information concerning
functional safety, refer to the Safety Manual.
**) After a power failure it can happen that the device switches off and then restarts
automatically.
Safe Isolation to EN 61140 by reinforced
insulation according to EN 61010-1.

For applications with high working volt-
ages, ensure there is sufficient spacing
or isolation from neighboring devices
and protection against electric shocks.
