• Turn off the power to the YW series before starting installation,
removal, wiring, maintenance, and inspection of the products. Failure
to turn power off may cause electrical shocks or re hazard.
• To avoid burning your hand, use the lamp holder tool when replacing
lamps.
• For wiring, use wires of a proper size to meet the voltage and current
requirements. Tighten the M3.5 terminal screws to a tightening
torque of 1.0 N·m. Failure to tighten the terminal screws may cause
overheating and re.
Panel Mounting
• Remove the contact block from the operator (for pilot lights, remove the
transformer or full voltage unit from the pilot light). Remove the locking ring
from the operator. Insert the operator into the panel cut-out from the front,
tighten the locking ring from the back, then install the contact block to the
operator.
Removing and Installing the Contact Block
➀ Pull up the locking lever.
➁ Turn the lever to the left.
➂ Pull out the contact bloc
k
1. To remove the operator from the contact block, pull up the locking lever and
turn it to the left. Then the operator can be pulled out.
2. To reinstall, place the TOP marking on the operator and the TOP marking
on the contact block mounting adapter in the same direction, and insert the
operator into the contact block mounting adapter. Then turn the locking lever
to the right.
Removing and Installing the Transformer
1. Insert a flat screwdriver (5 mm wide at maximum) into the latch hole on the
transformer unit as shown in the photo below, and disengage the latch. Then
pull out the operator.
2. To reinstall, place the TOP marking on the operator and the latch in the same
direction, and push the operator into the transformer.

Removing the Full Voltage Unit
➁
➀
1. To remove the full voltage unit, squeeze the full voltage unit from both sides
to disengage the latch as shown, and pull it out. Like the transformer unit,
the full voltage unit can also be pulled out by inserting a flat screwdriver into
the latch hole as shown.
2. To reinstall, place the TOP markings on the operator and the latch on the full
voltage unit in the same direction, and insert the operator into the full voltage
unit.
Notes for Panel Mounting
1. Use the optional locking ring wrench (MW9Z-T1) to mount the operator onto
a panel. Tightening torque must not exceed 2.0 N·m. Do not use pliers.
Excessive tightening will damage the locking ring.
2. For contact blocks and transformers housing LED and incandescent lamps,
make sure not to press the lamps too hard, otherwise the lamp socket may
be damaged.
