Digital Inputs Connection
There are provisions for three separate digital inputs. These can be configured to operate in two
different ways. Refer to Digital Input Configuration section on page 8-1 for configuration details. To
connect the device monitored, connect to one of the three inputs located on the rear of the unit. If only
a switch "open/close contact" mode is being used, then polarity is not important. However, if a voltage
source is being used, then the polarity will need to be correct.

Caution
: Pay close attention to polarity and voltage when making these connections. Connecting
the digital inputs polarity backwards or exceeding 60Vdc in voltage mode will damage the equipment.
