Cabling the Candeo
There are eight configurable Candeo output ports for output alarms. Each
output port can use one of the following three contact types: normally open,
normally closed, and common. Large Systems use normally closed contacts.
Common contacts connect to the Candeo battery return bus. The connector
strip J8 is used for all output connections and is removable from the System
Manager for ease of wiring. Ensure that pin 1 is in the correct orientation for
wiring when strip has been removed.
Configuring the alarm ports
Follow the steps in Procedure 17 to configure the alarm ports.
