10 Replacing the Backlight

9 Input/Output Signal Line Cautions

• Input and Output signal lines must be separated from the power control cables

for operational circuits.

• If this is not possible, use a shielded cable and the shield should be grounded.

• To improve noise immunity, it is recommended to attach a ferrite core to the

power cord.

Using any backlight other than the model written above may

cause an accident or PS-A unit malfunction.

8 Grounding Cautions

• When attaching a wire to the PS-A's bottom face FG terminal, (on the AC

Connector), be sure to create an exclusive ground.

• FG and SG terminals are internally connected in the PS-A. When connecting to

another device, be sure to create an SG shorting loop in your system.

*1 Use a grounding resistance of 100

Ω

, a wire of 2mm

or thicker, or your country's

applicable standard.

• Input and Output signal lines must be separated from the power control cables

for operational circuits.

• To increase the noise resistance, be sure to twist the ends of the power cord

before connecting it to the PS-A unit.

• The PS-A unit's power cord should not be bundled with or kept close to main

circuit lines (high voltage, high current), or input/output signal lines.

• Connect a surge absorber to handle power surges.

• Ground the lightning surge absorber and the PS-A separately.

• Select a lightning surge absorber which will not exceed the allow-

able circuit voltage, even when the voltage rises to the maximum.

• To reduce noise, make the power cord as short as possible.

estimated damages or losses, or third party claims resulting from the use of this product.

The PS-A unit's backlight is user replacable. For an explanation of how to replace

the PS-A's backlight, please refer to the Installation Guide which comes with the

replacement backlights (sold separately). The corresponding backlight is CA3-

BLU15-01.
