POWER WIRING
The power supplied to the meter 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.

COMM
CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the controller 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 plug-in cards with respect to input common.

USER INPUT WIRING
If not using User Inputs, then skip this section. User Input terminal does not need to be wired in order to
remain in the inactive state.
Sourcing Logic
(UACt Hi)
When the UACt parameter is programmed
to Hi, the user inputs of the controller are
internally pulled down to 0 V with 20
KW resistance. The input is active when
a voltage greater than 2.2 VDC is
applied.

Sinking Logic
(UACt Lo)
When the UACt parameter is

when it is pulled low (<1.1 V).
