•Turn off the power to the YW series control units before starting in-
stallation, removal, wiring, maintenance, and inspection of the
products. Failure to turn power off may cause electrical shocks or
fire hazard.
•To avoid burning your hand, use the lamp holder tool when replac-
ing lamps.
For wiring, use wires of a proper size to meet the voltage and cur-
rent 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 fire.
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
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 idec
marking on the contact block mounting adapter in the same direc-
tion, and insert the operator into the contact block mounting adapt-
er. Then turn the locking lever to the right.
Removing and Installing the Transformer Unit
1. Insert aat screwdriver (5 mm wide at maximum) into the latch
hole on the transformer unit as shown in the photo below, and dis-
engage 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
unit.
Removing the Full Voltage Unit
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 aat 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 opera-
tor into the full voltage unit.
Notes for Panel Mounting
1. Use the optional locking ring wrench (MW9Z-T1) to mount the op-
erator 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 incandes-
cent lamps, make sure not to press the lamps too hard, otherwise
the lamp socket may be damaged.
