Safety Precautions
• Turn off the power to the HW series control units before
starting installation, removal, wiring, maintenance, and
inspection of the products. Failure to turn power off may
cause electrical shocks or fire hazard.
• To avoid a burn on your hand, use the lamp holder tool
when replacing lamps.
• For wiring, use wires of a proper size to meet the volt-
age and current requirements. Tighten the M3.5 terminal
screws to a tightening torque of 1.0 to 1.3 N·m. Failure to
tighten terminal screws may cause overheat and fire.
Instructions
Panel Mounting
Remove the contact block from the operator (for transformer
pilot lights, remove the transformer from the illumination
unit). 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, turn the
locking lever in the direction of the arrow shown below.
Then the operator can be pulled out.
2. To reinstall, place the TOP markings on the operator and
the contact block mounting adapter in the same direction,
and insert the operator into the contact block mounting
adapter. Then turn the locking lever in the opposite direc-
tion.
Notes for Panel Mounting
When mounting the operator onto a panel, use the optional
locking ring wrench (MW9Z-T1) to tighten the locking ring.
Tightening torque must not exceed 2.0 N·m. Do not use
pliers. Excessive tightening will damage the locking ring.
Safety Lever Lock
IDEC strongly recommends using the safety lever lock
(HW9Z-LS, yellow) to prevent heavy vibration or mainte-
nance personnel from unlocking contacts.
1. HW series can be mounted vertically with a minimum
spacing of 50 mm (70 mm for mono-lever switches) but
spacing should be determined to ensure easy operation.
2. Mount the control unit onto the panel, lock the lever, and
strongly push in the safety lever lock to install.
3. When the spacing is narrower than the recommended
value, with the lever unlocked, mount the safety lever lock
and insert the contact unit to the operator. Then, lock the
lever and strongly push in the safety lever lock to install.
4. To remove the safety lever lock, insert a flat screwdriver
into the safety lever lock and push upwards.
