ELECTRICAL CONNECTIONS

!
DANGER!
Install a general automatic switch with characteristic delayed curve, of adequate
capacity and interruption power, in a protected area near the unit (the device
must be able to interrupt the presumed short circuit current, whose value should
be determined on the basis of the system characteristics). Earth connection is
compulsory by law to ensure user safety while the machine is in use.
!
DANGER!
in compliance with the regulations applicable in the country where the unit is
installed. Non-conforming electrical connections releases RHOSS S.p.A. from
liability concerning damage to objects and persons. In making the electrical
connections to the board, cables must be routed so that they do not touch the
from any burrs.
!
DANGER!
Check the tightness of the screws that secure the conductors to the electrical
components on the board (vibrations during handling and transport could have
caused them to come loose).
IMPORTANT!
For the electrical connections of the unit and accessories, refer to the relative
wiring diagram.
Check the voltage and mains frequency, which should be within the limit
of 400-3-50 ± 6%. Check the phase unbalance: it must be less than 2%.
Example:
L1-L2 = 388V, L2-L3 = 379V, L3-L1 = 377V
Maximum deviation from the average = 388-381 = 7V
Unbalance = (7 / 381) x 100 = 1.83 % (acceptable as it is within the
envisaged limit).
!
DANGER!
Operation outside the limits could affect correct machine operation.
The safety door interlock automatically prevents electric power being
fed to the unit if the cover panel over the electrical panel is opened.
After opening the front panel of the unit, feed the power supply cables
through the cable clamps in the external panelling and then through the
ducts at the base of the electric board.
The electrical power supplied by the three-phase line, must be taken to
use: for the section, refer to the following table or to the wiring diagram.

The earth conductor must be longer than the other conductors in order
to ensure that if the cable fastening device should become loose, it will
be the last to be stretched.

Remote management through connections prepared by
the installer
The connections between board and remote controls must be made with
shielded cable (make sure the shield is continuous throughout the length
of the cable) consisting of 2 twisted 0.5 mm² wires and the shield. The
screening must be connected to the earth screw on the panel (on one
side only). The maximum distance allowed is 30 m.
Lay the cables far from the power cables or cables with a different voltage
and cables that emit electromagnetic disturbance. Do not lay the cables
in the vicinity of appliances that could create electromagnetic interferen-
ce.

IMPORTANT!
When the unit is switched OFF using the remote control selector switch, the
message OFF by digital input appears on the control panel display on the
machine.
Remove the terminal jumper corresponding to SCR on the machine ter-
minal block (see wiring diagram) and connect the wires coming from the
remote control ON/OFF selector (selector to be installed by the installer).

Remote summer/winter enabling on THAEY
Connect the cables coming from the remote summer/winter selector
(SEI) on the terminal corresponding to SEI on the machine terminal block
(see wiring diagram). Change the relative SW parameter (see Electronic
Control Manual).
