- Page 3 To prevent potential fire or shock hazard, do not expose the instrument to rain or moisture. While installing Multi-Mon CTs to the secondary of an external third party current transformer, the external current transformer secondary output must never be allowed to be open circuit when the primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage, fire and even serious or fatal injury.

- Page 35 Multi-Mon has an embedded logical controller that runs different actions in response to user-defined internal and external events. Unlike a PLC, the Multi-Mon uses a simplified programming technique based on setpoints that allows the user to program a required action based on a measured analog value or on a time. The controller provides up to 4 setpoints for each submeter.
- Page 36 MULTI-MON Using Time Triggers If you want the setpoint actions to be synchronized with the clock, for example, to provide recording interval data, use the minute time interval trigger that generates periodic events synchronized with the device clock. Delaying Setpoint Operations Two optional delays can be added to each setpoint to extend monitoring a setpoint trigger for a longer time before making a decision on whether the expected event occurred or not.

- Page 40 Configuring Data Recorders The Multi-Mon provides a separate Data recorder for each metering submeter. The recorder is triggered via a setpoint periodically for recording interval data (see Using Alarm/Control Setpoints). The device memory is factory partitioned to allow recording one data log file per submeter (Data Log #1) with a maximum of 5000 records per file.
