Each appliance is accompanied by a complete connection and
wiring diagram enclosed. This contains full details of the
technical specifications (electrical rating, voltage, amperage
Check and ensure that the mains voltage agrees with the
voltage given on the specification plate.

set up in block configuration, all appliances must be
interconnected as potential equalization.
The appliance is designed for connection to fixed lines. If
the appliance is fitted directly to a masonry plinth without
an appliance plinth, the supply must be located at the
prescribed place. In this case, the protecting tube may not
protrude from the plinth. If a CNS base is used, the
protecting tube may not protrude more than 10 cm from the
After installation, the shock-hazard protection for live and
functionally insulated parts must be secured.
An isolating device working on all poles and with a
minimum contact opening of 3 mm must be provided on
When faulty-current circuit breakers are used, ones for a
rated tripping current of 30 mA should be used.
When using a faulty current-operated circuit-breaker (in the
case of an existing circuit-breaker and for new installations)
only a one pulse-current sensitive faulty current-operated
circuit-breaker may be connected in series in conjunction
with these appliances.

Power is taken from a ready-installed electric cable which
protrudes 1.5 m from the floor or the wall.
The connection terminals for the appliance are located behind
the front right-hand cover (B). In order to connect the
appliance, the front panel must be removed (see Chapter 2.1
on page 6).

Additional terminals for power optimizing systems (EO/SI) or
potential-free contacts (PK) for the external monitoring of the
appliance are available as options. The connections are made
as per the electrical diagram.

CONNECTION TO THE POTENTIAL
The appliance is to be connected to a potential equalization
system with a minimum conductor cross-section of 10 mm².
Use the appropriately marked terminal studs for this purpose
(EN 60 335). The connection consists of an M6 threaded bolt
and is located on the frame of the appliance.
