NOTICE!
Before starting with connections, check that the order code of the unit's electri-
cal equipment matches the wiring diagram. For units with external thermal con-
tact, the alarm signal can be tapped off. Refer to the unit connection diagram
for connecting terminals with error messages. According to the relevant regu-
lations, an all-pole isolating device must be provided by others on site.
