MOUNTING POSITION - The OPR-4 MUST be mounted in a vertical position, as shown above.
POWER INPUT - The OPR-4 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.
UP
RELAY OUTPUTS - The OPR-4 has four KYZ pulse outputs, that can be used as either 2-Wire (Form A) or
3-Wire (Form C). They are K1,Y1, & Z1 for output #1; K2,Y2, & Z2 for output #2; K3,Y3, & Z3 for output #3;
and K4,Y4, & Z4 for output #4. For 2-Wire mode, the K & Y or the K & Z terminals may be used. For 3-Wire
mode, all three wires must be used. Relay outputs are electrical isolated, dry-contact type with NO sourced
voltage. The user must supply their own wetting voltage.

FUSE - The power supply fuse (F1) supplied on the OPR-4 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 OPR-4 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 electrical system
ground can be connected to the OPR's chassis. Do not tie the Ground and Neutral terminals together.

Fiber Optic Cable Connections -Locate the two "ST" fiber optic ports on the OPR-4's media convertor
module. Connect the fiber optic cable to these ports using the twist lock connections. The cables should be
"crossed" such that each cable is connected to the "T" fiber optic port on one end and the "R" fiber optic port
on the other end.
The OPR-4 will receive pulse information from the OPT-4 Optical Fiber Pulse Transmitter up to
approximately 5000 meters or about 3 miles using multimode fiber. Care should be taken to follow all proper
fiber optical cable implementation standards. See the System Block Diagram below.
