Electric shock warning
Faulty electrical installation or excessive
mains voltage can lead to electric
shock. When connecting the freshness
cooler, take into account the valid regu
-
lations of the local electrical supply com
-
pany for your region, as well as all gene
-
rally applicable national standards and
safety regulations and comply with
them. Make sure that the circuit is ade-
quately protected. Only connect the
freshness cooler if the mains voltage and
mains frequency of the socket corre
-
spond to the information on the rating
plate.
Only allow work on the electrical system
to be carried out by KMW-authorised
specialists. Also only have a damaged
power cord replaced by KMW-authori
-
zed specialists.
Do not connect the freshness cooler to
multiple socket strips and do not use ex-
tension cords.
Observe the following criteria for the
power supply and connection compo
-
nents:
All supply cables must be laid by a spe
-
cialist electrician in accordance with
the VDE 0100-410 standard. Only con
-
nect the cooler to earthed sockets with
earthing contact. Never connect more
than two devices to a circuit. The cable
length is 300 cm.
Make sure that the fresh food cooler
does not switch off automatically when
the market light is switched off.
Make sure that no other consumers are
connected to the sockets for connec-
ting the fresh food cooler.
KMW recommends using a cable duct
on the floor with sockets built into it or
mounted on it to connect the cooler.
Electric circuit protection
Before connecting the freshness cooler
to an electrical circuit, you must ensure
that the corresponding electrical circuit
is correctly secured. Miniature circuit
breakers (LS switches) for protection
against overcurrent and residual current
circuit breakers (FI switches) for protecti-
on against residual currents are required
for the proper protection of the circuit.
In addition to separate solutions for LS
and FI switches, it is also possible to install
a combined FI/LS switch.
Slow circuit breakers
To ensure optimum operational safety,
KMW recommends securing each de-
vice with its own slow-blow circuit brea-
ker. Slow-blow miniature circuit breakers
(LS switches) represent the minimum
requirement for protecting the circuit.
The LS switches used for this must meet
the following criteria:
• LS switch with 16A
• KMW recommends tripping charac-
teristic „C“; however, „B“ can also be
used.
Connect and disconnect the cooler from
the power supply
The freshness cooler is equipped with a
dark and a light connection cable.
Plug the dark mains plug into a properly
installed safety socket to connect the
freshness cooler to the mains. The fresh-
ness cooler starts to cool automatically
with a delay of 2 minutes.
During commissioning, the
controller time must be adjus-
ted to the current time of
dayn
Plug the light-colored mains plug into the
controllable socket of the store‘s central
light control to connect the LEDs of the
freshness cooler.
