* In case of a current fault above 60A (120 for the H version), all adjacent channels will report
higher than actual readings. To prevent this from causing over-current warnings and alarms,
configure the warning and alarm delays for a longer time period than the response time of the
breaker.

NOTICE
DANGER
1. Disconnect and lock out power.
2. Mount current sensor strips adjacent to breaker terminations.
3. Verify that serial numbers on CT and board match.
4. Mount board onto electrical/fire enclosure.
5. Connect CTs and wire the board.
6. Reconnect power.
7. Configure communication and addressing parameters.
Note: Data acquisition board and CT strips are calibrated as a set. Match the serial
numbered parts together.
