MOUNTING POSITION -
The OPT-1 may be mounted in any position.
POWER INPUT -
The OPT-1 can be powered by 120VAC or 208 to 277VAC. Connect the GND terminal to
the electrical system ground. Connect the Neutral lead to the NEU terminal. Connect the L1 terminal to the
120VAC "Hot" lead for 120VAC operation. Connect the L2 terminal to the 208, 240, or 277 "Hot" lead.
Do
not use both L1 and L2. Exercise caution when board is energized. There is voltage present at L1
and L2 when powered.
METER INPUTS -
The OPT-1 has one pulse input which can be configured as either 2-Wire (Form A) or 3-
Wire (Form C). Connections are K1,Y1, & Z1 and connect to the meter's K,Y, & Z output terminals. For 2-
Wire mode, use the
K
and
Y
terminals. For 3-Wire mode, all three wires must be used. The meter's pulse
output must be a dry-contact type with NO sourced voltage. The OPT-1 supplies its own wetting voltage to
the KYZ pulse output contact of the meter.

Form A or C
FUSE -
The power supply fuse (F1) supplied on the OPT-1 is 1/2 Amp, type 3AG. Because the power
supply voltage terminals are configured as 120V (L1) and 208-277V (L2), the fuse is located in the neutral
power supply lead. Voltage may be present on the L1 and L2 terminals and circuitry on the board when the
fuse is blown. Care should be exercised to disconnect all power to the board at the circuit breaker before
servicing the system.

GROUND -
The GND terminal on the OPT-1 is a common ground with the chassis and is connected to the
Chassis by means of the middle right-hand mounting screw. Therefore, if necessary, the electric a l s y s t e m
ground can be connected to the OPT's chassis. Do not tie the Ground and Neutral terminals together.
