ERT Battery Pack Protection Circuit

ERT Battery Packs have an internal protection circuit. The circuit opens to protect the
battery if the battery voltage drops below a preset threshold. The circuit protects the
battery from going into a deep discharge state. The circuit will activate in the event the
battery is left connected to the ERT Module overnight.

Setting the 50/60 Hz notch filter

The notch filter is selected for 50 or 60 Hz using a screw near the Battery Pack Cable
connection. For 60 Hz remove the screw, for 50 Hz leave the screw in place. The filter
setting is reported in PC-sam's SYSYEM INFO window .
