Note:

Replacements are not possible other than for those items

listed in the bill of materials.

Other than the AC jack, the power switch, the fuse, and the

LED indicator, you cannot replace the parts on the printed

circuit board.

Alert: After the repairs have been completed, please per-

form a Megger insulation test on the ground side of the AC

jack and the charger terminal. The standard is 2MΩor more.

Removing the Upper Case

1. Remove the 10 screws (

q) from the upper case.

2. Raise the case while pulling forward underneath where

the power switch hole is located (

w,e).

(When pulling on the case without raising it, it will catch

where the power switch hole is located.)

Removing the Charging Slots

1. Remove the 11 screws (

q) from the aluminum plate

and the 2 screws (

w) from the charging slots to remove

the aluminum plate and insulating sheet.

2. Remove the 12 screws (

e) holding the printed circuit

board to the charging slots to remove the charging slots.

Note: Refer to ﬁgure (

r) during the removal in order to

retain the shading tubes of the LEDs.

Removing the Illumination Guide

Removing the Charging Terminal

1. While pushing down on the protruding charger terminal,

slide the terminal out.

Note: Clean the charger terminal landing by wiping it

with an alcohol dampened cloth.

Installing the Shading Tube

1. After installing the charging slots onto the printed circuit

board, verify that the shading tubes cover the heads of

the LEDs.

Installing the LEDs

1. Install the LEDs onto the printed circuit board in the man-

ner shown in Exploded view.

Installing the Charging Slot

1. When installing the charging slot to the PCB, tighten the

screw in the direction indicated (right edge).

TROUBLE SHOOTING

The LED does not light up,

or red blinks.

Is 16V DC voltage? Is not the fuse

(F53-0428-08)

blowout?

Malfunction the PCB.

Note:

Measuring condition: With the charging slot installed to the PCB.

Replace the fuse (F53-0428-08).

Is the voltage of

0.6V~4.0V output to

the T terminal?

Replace the terminal of +1 or +2.

The LED does not light up,

or red blinks.

Yes

Malfunction the PCB.

Yes

Replace the terminal of T.

Is voltage
