2 Installation and Wiring

Mounting the Main Unit

 Mounting the Main Unit on a DIN rail

1 Align the claw at the bottom of the main unit with the

DIN rail, as shown in the figure. While pushing the main body in the direction of arrow 1, push down in the direction of arrow 2.

2 To remove the sensor, raise the main body in the

direction of arrow 3 while pushing the main body in the direction of arrow 1.

 Installation on a wall (main unit only)

1 Attach the main unit to the optional mounting

adapter (OP-88245), and then insert M3 screws into the two locations shown in the figure to secure the main unit in place.

Connecting Multiple Amplifiers

Up to 16 expansion units can be connected to 1 main unit. However, each dual output type will be treated as 2 expansion units.

When connecting to multiple amplifiers or when mounting main units together, mount the units on a DIN rail installed on a metal surface.

•

Be sure to turn the power off before connecting multiple expansion units.

•

Do not touch the expansion connector.

1 Remove the protection covers from the main unit

and expansion unit(s).

Package Contents

• Main unit • Instruction manual

This is a direct current (DC) power supply type sensor. Application of an alternating current may result in explosion or fire.

•

Use separate conduits for power lines and high-voltage lines. Use of a common conduit may result in device malfunction due to noise or damage to the sensor.

•

Always ground the frame ground terminal when using an off-the-shelf switching regulator.

•

Do not use this product outdoors.

2 Install the amplifiers on the DIN rail one at a time.

3 Slide the main unit and expansion unit(s) together.

Mate the two claws of the expansion unit with the recesses on the main unit side until a click is heard/ felt.

4 Attach the end units (optional, sold separately:

OP-26751) to the DIN rail on both sides of the amplifiers in the same way as step (2).

5 Secure the amplifiers between the end units.

Tighten the screws from the top (two screws × two units) with a Phillips screwdriver to fix the end units in place.

Fiber Unit Installation

 Using a fiber cutter

1 Insert the fiber into the cutter hole. 2 Bring down the blade in a single, swift

motion to cut the fiber. (Do not use a hole that has already been used.)

 Connecting to the amplifier unit

1 Open the cover (1), and then lower the lever in the

direction indicated by (2).

2 Insert the fiber unit into the installation holes

(approximately 14 mm). (3)

3 Move the lever back in the direction indicated by

(4).

When installing a coaxial reflective fiber in the main unit, install the single-core fiber in the transmission installation hole and the multi-core fiber in the reception installation hole.
