Common Precautions

Recommended circuit breakers and fuses

• Product failure may result in fire or electric shocks. Therefore,

always use the recommended circuit breaker or fuse.

• To ensure conformance to safety standards, and secure safety of

the Unit, connect an input to the Unit via the recommended circuit
breakers or fuses indicated in the table below.

• A circuit breaker or fuse can be changed only by the indicated

person or skilled person.

Note:

For the S8VK-WB, the DC input is not compliant with Safety

standards.

• If multiple Units are used through crossover wiring, select the

circuit breaker or fuse in view of the input current and inrush
current.

Wiring method

• Connect the input as shown in the figure below.
• In the case of a three-phase four-wire system, do not connect the

ground and neutral wire, but connect the other three wires to “L1/
+, L2, L3/-”.

Wiring

• This is the protective earth terminal specified in the safety

standards. Connect the ground completely. Electric shock or
malfunction may occur if the ground is not connected completely.

• Minor fire may possibly occur. Ensure that DC input and output

terminals are wired correctly.

• When you insert wires or insert a screwdriver into a release hole,

do not press down on the terminal block with a force of 40 N or
greater (100 N or greater for the output terminal block of S8VK-
W

960

only).

• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a

release hole on the terminal block. The terminal block may be
damaged.

• Insert a flat-blade screwdriver into the release holes at an angle.

The terminal block may be damaged if you insert the screwdriver
straight in.

• Do not allow the flat-blade screwdriver to fall out while it is inserted

into a release hole.

• Do not bend a wire past its natural bending radius or pull on it with

excessive force. This may cause a wire to be broken.

• Do not insert more than one wire into each terminal insertion hole.
• Do not pre-solder the ends of the wires. Doing so will inhibit proper

connection.

• Be sure to remove the sheet covering the S8M for machining

before power-ON so that it does not interfere with heat dissipation.

• If there is a possibility of vibration or shock, please use wires and

stranded wires with ferrules.

• Minor fire may occasionally occur.

Always check the voltage of the equipment when replacing the
Unit, and be sure to use a conforming product.

• Use the following material for the wires after confirming the rating

of the wires in order to prevent smoking or ignition.

• Use copper stranded or solid wires. However, solid wires can not

be used for the S8VK-W

960

output terminal.
