The parts marked with * are not supplied and should be prepared
by the user. The screw size depends on the L-shaped bracket
size, as shown below.

Replacement/Expansion/Reduction of LED Modules
• Make sure to turn power off.
• When expanding/reducing the LED modules, make sure
to use the center screw set of the correct length.
• Insert a at screwdriver into the recess as shown below,
lift up the cap, and remove the cap with your hands. Use
a at screwdriver with a tip of 1-mm thick and 7-mm
wide maximum.
• Remove the center screw before reassembling the LED
modules.
• When assembling the LED modules, make sure to align
the recess of the cap with the recess of the LED module.
Otherwise, damage may result.
Recommended tightening torque: 0.4 to 0.5 N·m.

• Note the correct orientation when assembling the LED modules.
• Tighten the screws to the recommended tightening torque.
The LED module may be damaged if the screw is loose dur-
ing operation.
• Do not touch the metal plug on the LED module. Other-
wise, LED elements maybe damaged due to static elec-
tricity.
• Use a maximum of 5 tiers.
• Select an optional screw of an appropriate length de-
pending on the number of tiers.
• Do not remove the packing from the LED module. Other-
wise, waterproof characteristics will be impaired.

Wiring
• For wiring, see the wiring diagrams on pages 9 and 10.
• Incorrect wiring may damage the internal circuit.
• Be sure to insulate unused wires.
• Connect a 1A fuse to the power line as shown in the Wir-
ing Examples on pages 9 and 10.
• Use a UL listed external fuse holder.
• Use a class 2 power supply only.
• When using LED modules of the same color for two or
more tiers, determine contact capacity in consideration of
the LED current, because only one wire is used to light all
tiers of the same color.
• Do not apply voltage to ashing (brown) lines.
• Do not connect ashing (brown) lines with the power
lines. The internal circuit may be damaged.
• Do not turn on steady and ashing lines simultaneously.
• Do not turn on alarms 1 and 2 simultaneously.

Sound Volume Adjustment
• Move the sound volume lever to the right and left to ad-
just the sound volume.
• The sound volume is at maximum when the lever is set to
the right.
• The sound volume adjustment lever may be damaged if
forcibly moved.
Highest Temperature Limitations
The highest temperature is limited to 50ºC when all tiers
are lit continuously in the following combinations:
1. Three tiers
Two or more tiers of blue and green
(example: Red-Green-Blue, Green-Green-Red)
2. Four or ve tiers
(example: Red-Yellow-Green-Pure White,
Red-Yellow-Blue-Green-Pure White)
