Type No. RV8H-L- , RV8H-S-
Read this instruction sheet to make sure of correct operation before starting installation,wiring, operation, maintenance, and inspection of this product. Also make sure that this instruction sheet is kept by end users.
Safety Precautions
Turn off power to the sockets before starting installation, removal, wiring, maintenance, and inspection of the sockets. Failure to turn power off may cause electrical shocks or fire hazard.
Use proper wires to meet the voltage and current requirements.
Make sure that relay and output equipment are connected completely. Incomplete connection may cause overheat, resulting in fire hazard.
To ensure safety, make sure that all descriptions in the operation instructions are followed strictly.
Prevent metal fragments and pieces of wire from dropping inside the sockets. Ingress of such fragments and chips may cause fire, failure, or malfunction.
Use a 15A non-time delay fuse for protection against short-circuit.
When lightening surge may enter the input circuit of types AD12, AD18, and AD24, and when lightening surge and noise may enter the input circuit of types AD48 and AD60 of the following products, use a proper varistor. Otherwise, failure maybe caused.

1.3mm max. or AWG16 max., CU(copper) solid wire : 2 max.
Strip the wire insulation 7 to 8 mm from the end.
Stripping the wire insulation too short may cause the wire to come off. Stripping the wire insulation too long may cause short-circuit with the adjacent socket. Make sure to twist the stranded wire to prevent loosening. For wiring, use the following applicable screwdriver.

Wiring Instructions
1.Insert the optional screwdriver (BC1S-SD0) or an applicable screwdriver into the square-shaped port as shown,until the screwdriver tip touches the bottom of
the spring.
3.While the screwdriver is retained in the port, insert the wire of ferrule into the round-shaped wire port. Each wire port can accommodate one wire or ferrule. When connecting two wires to one
terminal, use the adjoining port of the same terminal.

2.Push in the screwdriver until it touches the bottom of the port. The wire port is now open, and the screwdriver is held in place.
The screwdriver will not come off even if you release your hand.
4. Pull out the screwdriver. The connection is now complete.

Correct |
When using wire with insulation diameter or 2.0mm or less, do not insert the wire too
deep where the insulation inserts into the
spring clamp opening. Otherwise conductive failure will be caused.
Make sure that the wire insulation is stripped 8 to 9 mm and the wire is inserted
to the bottom.

3.Removing the Relay
Open the release lever in the direction of the arrow, and remove the relay.
The relay may pop out when opening the release lever, resulting in possible damage or loss of the relay. To prevent this, rightly press down the relay using a finger when opening the release lever.
Do not open the release lever more than 90 , otherwise the socket will be damaged.
4.Installing the Relay
Open the release lever, and insert the relay into the socket until the bottom of relay touches the projection A on the socket. Close the release lever until it is latched.
When installing the relay, do not press in using a relay. Make sure to use the release lever, otherwise the projection A will be damaged.
5.Installing the socket
Put the groove on the socket(part B) on the DIN rail, and press the socket towards the DIN rail as shown in the figure.
