Connections to the EnCal 3000 Interconnection board
The drawing below shows the top lay-out of the Interconnection Board at the bottom of the unit. It contains all the con-
nectors for external cables (marked with grey). For flame retardant wiring use cables according an ISO norm. To fulfill
the FM regulations always use cables / wiring according to UL94 V-1 or equal for installation. All the wiring with the
other electronic boards is done in the factory, and may not be changed during field installation.
