Electrical installation of the ME 1030 module consists
in connecting the electric plug to the socket. The de-
vice has been equipped with a power cord terminated
with a socket plug with earthing.
• ME 1030 is supplied with a power cord with
1-phase earthed plug, which has to be connect-
ed to a properly installed 230VAC wall outlet with
protective earth pin.
• Electrical installation, which will be connected to
the heater, should be made in accordance with
current regulations.
• Install a circuit breaker in the module power sup-
ply line, in order to quickly disconnect the module
from the mains.
• The electrical installation must be equipped with
a residual current circuit breaker (RCCB) with a
value of max. I
ΔN
=30mA.
• In the absence of RCCB, use an overcurrent CB
with residual current module with a value of max.
30 mA.
• It is forbidden to make changes in the field of
electrical connections in the device. Any modifi-
cations in the topology of the electrical connec-
tions consisting of installation of circuit breakers
should be carried out by a authorized personnel.
• Ensure the heater is connected to the electrical
system in the TN-S or TN-C-S earthing system..
• For the connection use a four-core 300/500V copper
cable, with a minimum cross-section according to Ta-
ble 1, entering the module through the cable gland in
the housing; the module must be connected to the
electrical system permanently.
• The types of protections installed on the heater
are in Table 1 .
• Connect wires L1, L2, & L3 to the electrical con-
nector at terminals L1, L2, & L3.
• Connect the protective conductor of the electrical
system to the PE terminal on the rear panel.
• To protect the heater it is recommended to install
a circuit breaker on the line supplying the heater.
• The electrical system must be equipped with a residu-
al current circuit breaker with a maximum of I
ΔN
=30mA.
• It is forbidden to make changes in the field of
electrical connections in the device. Any modifi-
cations in the topology of the electrical connec-
tions consisting of installation of circuit breakers
should be carried out by a authorized personnel.
After installing the heater, remove the upper cover and
connect the power cord (3-phase) according to the wir-
ing diagram inside the casing (see
Fig. 4
or
Fig. 5
).
