CAUTION:
Sensor input common is NOT isolated from user input common. In order to preserve the safety of the application, the sensor input common
must be suitably isolated from hazardous live earth referenced voltages; or input common must be at protective earth ground potential. If not, hazardous
live voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential of the
user input common with respect to earth common; and the common of the isolated option cards with respect to input common.

: Before connecting signal wires, verify the T/V Jumper is in the T position.

The power supplied to the unit shall employ a 15 Amp UL approved circuit breaker for AC input and a 1 Amp, 250 V UL approved fuse for DC input. It shall be
easily accessible and marked as a disconnecting device to the installed unit. This device is not directly intended for connection to the mains without a reliable means
to reduce transient over-voltages to 1500 V.
