COMPONENTS
Electric Control Board
Contains the power section and the manage-
ment of controls and safety devices.
It is in compliance with the following Standards
IEC EN 61000-6-1
IEC EN 61000-6-3 (electromagnetic immuni-
ty and emission for residential environments).
IEC EN 61000-6-2
IEC EN 61000-6-4 (electromagnetic immuni-
ty and emission for industrial environments).
With the Directives regarding electromag-
netic compatibility EMC 89/336/CEE and
92/31/CEE and LVD 2006/95/CE
.
Door-lock isolating switch
The electric control board can be accessed
by removing the voltage. Act on the open-
ing lever of the control board itself. This
lever can be locked using one or more
padlocks during maintenance interventions
to prevent the machine being powered up
accidentally.
Control board
Allows the complete control of the appli-
ance. For a more in-depth description
please refer to the user manual.
Remote control panel
Allows to control the chiller at a distance.
Compressors magnet circuit breaker pro-
tection;
Fans magnet circuit breaker protection;
Auxiliary magnet circuit breaker protection;
Exhaust gas temperature control thermo-
stat.
