During normal operation (front cover closed), the unit can be quickly
disconnected from the main power line, setting to OFF the relevant circuit
breaker located on the electric switchboard.
During maintenance (front cover opened) it is possible to turn-on the unit by
setting to SERVICE MODE the SW2 switch, mounted on the RTM Supply Assy.
This switch is connected in parallel with the relay, controlled by the POWER ON
command, and during normal operation must be set to NORMAL. During
maintenance, in order to prevent RTM occasional turning-on it is better to
disconnect and insulate, momentarily, PWON terminal from the relevant
terminal board.
NOTE
Main power line is always present on terminal board and on
fuses
