Operating instructions
1 Safety instructions
Installation only by persons with appropriate electrotechnical knowledge and experience
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.
Contact an electrical contractor!
Serious injuries, fire or property damage possible. Please read and follow manual fully.
To protect against high-energy surges, install multistage selective protection. Otherwise con-
nected devices may be damaged.
These instructions are an integral part of the product, and must remain with the end customer.

SCHUKO socket with surge voltage protection
3 Intended 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.
4 Instructions 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.
5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the corresponding cir-
cuit breakers. Cover up live parts in the working environment.

(5) Load
￭ Connect surge protection socket outlet according to connection diagram for single socket
outlet (Figure 2) or connection diagram for socket outlet combination (Figure 3).
The maximum continuous voltage (see Technical data) must not be exceeded. In multiple
combinations, when a surge protection socket outlet is used the other socket outlets used
in the combination are also protected in the normal design. For this the socket outlets
have to be installed on the same conductor.
￭ Install overvoltage protection socket outlet in appliance box.
￭ Mount the cover and frame. Observe correct installation position. Otherwise the LED will
not function.

SCHUKO socket with surge voltage protection
This device can protect connected loads only up to the protection level specified in the
technical data. Surge voltages that are higher than that may still damage the connected
devices. The same applies for devices that require a lower protection level. For this
reason we accept no liability for any damage to the connected loads.
7 Troubleshooting
Acoustic signal sounds and red light emitting diode lights up.
Overvoltage protection has failed due to high over voltage. The socket outlet continues to sup-
ply connected loads with mains voltage, but with no protection function.
Have the surge protection socket outlet exchanged by an electrically skilled person.
Pull the mains plug to cut off the acoustic signal. The signal tone will sound again when
the plug is reinserted.
RCD protection switches trip.
The discharge of high over voltages to earth by the overvoltage protection can cause RCD pro-
tection switches to trip.
Use RCD protection switches with a high peak withstand current.
8 Warranty
The warranty is provided in accordance with statutory requirements via the specialist trade.
