in the following areas:in the following areas:

– The "5 safety rules" to be observed are: disconnect; secure against reconnection; determ-

ine that no voltage is present; ground and short-circuit; cover or block off adjacent live

parts

– Selection of suitable tools, measuring devices and, if necessary, personal protective

equipment

– Evaluation of the measurement results

– Selection of the electrical installation material to ensure the shutdown conditions

– IP degrees of protection

– Installation of the electrical installation material

– Type of mains supply (TN system, IT system, TT system) and the resulting connection re-

quirements (classic earthing, protective earthing, necessary additional measures, etc.)

Improper installation endangers your own life and the lives of users of the electrical system and

there is a risk of serious damage to property, e.g. through fire. You are at risk of personal liabil-

ity for personal injury and damage to property.

SCHUKO socket with surge voltage protection

33 Intended use

Intended use

Intended useIntended use

– Type 3 fine protection for protecting electrical and electronic devices against transient

power surges according to EN 61643-11

– For use only in combination with Type 1 coarse protection and Type 2 medium protection

– For use in TN, TT and IT systems

– Stationary installation indoors in appliance box according to DIN 49073.

44 Instructions for operation

Instructions for operation

Instructions for operationInstructions for operation

– The device protects electrical and electronic devices against transient power surges.

– Failure of the protection function is indicated by an acoustic and visual signal.

– Keep cables between loads (5) and surge protection socket outlet (1) as short as possible,

max. 4 m.

– Do not lay protected cables parallel to unprotected cables. There is a danger of surge

voltage coupling.

– When performing insulation measurements on the system, all surge protection products

should always be disconnected, because otherwise the test voltage will be limited by the

protective modules, thus leading to incorrect measurements.
