Safety Precautions
Turn off the power to the fl ush silhouette LW series before installation, removal,
wiring, maintenance and inspection. Failure to turn power off may cause an
electrical shock or fi re hazard.
To avoid burning your hand, use the lamp holder tool when replacing lamps.
For wiring, use the correct size wires to meet voltage and current requirements.
Solder correctly according to the instructions in Wiring and Terminal Cover
(below and on following page). Tighten the M3.5 terminal screws to a torque
of 0.6 to 1.0N·m. Failure to tighten terminal screws may cause overheating and
increase risk of fi re.
General Instructions
Panel Mounting
Remove the contact block from the operator. Insert
the operator into the panel cut out from the front,
then install the contact block.
Removing the Contact Block
Turn the locking lever on the contact block in the
direction opposite to the arrow on the housing.
The contact can then be removed.
Installing the Contact Block
Insert the contact block, with the TOP markings
on the contact block and the operator placed in
the same direction. Then lock the units, turning
the locking lever in the direction of the arrow.
Notes on Mounting
Use the optional locking ring wrench (LW9Z-T1)
to mount the operator into the panel. Tighten-
ing torque should not exceed 1.2N·m. Do not
use pliers. Excessive tightening will damage the
locking ring.
Collective Mounting
As the locking lever can be turned easily from the
rear of the units using a screwdriver, the contact
blocks can be removed even when mounted
collectively.

Replacement of the Lens & Marking Plate
Removal
To remove the lens unit, press the suction cup of
the optional lens removal tool (MT-S01) onto the
lens and pull the lens unit out.
Remove the marking plate by pushing the lens
from the rear to disengage the latches between
the lens and the lens holder, using a screwdriver
as shown below.
The translucent fi lter in the lens holder cannot be
removed because the fi lter is sealed to make the unit
waterproof and oiltight.
Installation
For round lenses, place the marking plate on
the lens holder with the anti-rotation projection
engaged and press the lens into the lens holder
to engage the latches. For square lenses, insert
the marking plate into the lens, and press the lens
into the holder to engage the latches.
Make sure of the correct orientation of the mark-
ing plate.
