6-Wire Bridge Input
Before connecting signal wires, the Input Range Jumper and Bridge Excitation Jumper should be verified for proper position.
4.3 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 inactive state.
Sourcing Logic (USrACt HI)
When the USrACt parameter is
programmed to HI, the user inputs of
the meter 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 (USrACt LO)
When the USrACt parameter is
programmed to LO, the user inputs
of the meter are internally pulled up
to +3.3 V with 20 KW resistance.
The input is active when it is pulled
low (<1.1 V).

See appropriate plug-in card bulletin for wiring details.
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.
