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.

INPUT SIGNAL WIRING
IMPORTANT
: Before connecting signal wires, the Input Range Jumper and Bridge Excitation Jumper should be verified for proper position.
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 K
W
resistance. The
input is active when a voltage greater
than 2.2 VDC is applied.

)
When the
USrACt
parameter is
programmed to
LO
, the user inputs
of the meter are internally pulled up
to +3.3 V with 20 K
W
resistance.
The input is active when it is pulled
low (<1.1 V).
