6.5.3 Finished Grounding Wires
Internal and external grounding are shown here, as well as an
alternate external grounding point. Always follow local electrical
guidelines.
6.6 Alarm Contact Setup
The alarm contacts can drive external alarms such as a light or buzzer.
By default, the three relays are set for normally open (NO) operation,
meaning that contact is closed when in alarm.
You can separately change each relay from normally open to
normally closed (NC) operation by changing the position of the
jumpers on the internal printed circuit board.
