All alarm and error outputs are open-collector outputs. The connection methods
of these outputs are the same as those of the open-collector control outputs.
Caution Alarm and error outputs are not protected from excessive current flow and volt-
age (exceeding 50 mA at 30 VDC); be sure to wire them correctly to protect inter-
nal circuits from damage.
CT Inputs CT terminals are not polarity sensitive and may be connected as desired to the
CT input terminals.
