NDS POWERSERVICE PLUS 25 User Manual page 29

on-off (0-1) switch
The switch on the device must always be left in the ON position
(1), for normal operation.
If the switch is set to OFF (0), the powerservice is disabled only
from the "Alternator" charge source, then it continues to
operate from the solar panel and / or 230V mains (for the GOLD
model), but it will not work while the engine is running. The
switch should be set to OFF (0) only if the device malfunctions,
disconnecting it when the engine is switched on, and allowing
the battery to be charged using the alternator directly, using
the original system.
