Precautions
Cautions
When a rod or wired-type actuator is used, do not touch the top end
of the actuator. Doing so may result in injury.
Applicable models: WLHAL5 and WL01HAL5 Rod Spring Levers
and WLNJ-S2 and WL01NJ-S2 Steel-wire Actuators.
Correct Use
A short-circuit may cause damage to the Switch, so insert a circuit
breaker fuse, of 1.5 to 2 times the rated current, in parallel with the
Switch. In order to meet EN approval ratings, use a 10-A fuse that
corresponds to IEC269, either a gI or gG.
When wiring terminal screws, use M4 round crimp terminals and
tighten screws to the recommended torque. Wiring with broken
wires, or the incorrect crimp terminals, or not tightening screws to
the recommended torque can lead to short-circuits, leakage cur-
rent, and fire.
When performing internal wiring there is a chance of short-circuit,
leakage current, or fire, so be sure to protect the inside of the Switch
from splashes of oil or water, corrosive gases, and cutting powder.
Using an inappropriate connector or assembling Switches incor-
rectly (assembly, tightening torque) can result in malfunction, leak-
age current, or fire, so be sure to read the instruction manual thor-
oughly beforehand.
Even when the connector is assembled and set correctly, the end of
the cable and the inside of the Switch may come in contact. This can
lead to malfunction, leakage current, or fire, so be sure to protect the
end of the cable from splashes of oil or water and corrosive gases.
Environmental Precautions
When the Switch is used in locations subject to splashes of water or
oil, the material of the seal, which ensures the sealing properties of
the Switch, may undergo changes in shape and quality. This is due
to deterioration (including expansion and contraction), and may re-
sult in reduced performance, ineffective return, and ineffective seal-
ing (leading to ineffective contact, insulation, leakage current, and
fire). Confirm the possible effects of the operating environment on
the Switch before use.
Built-in Switch
Do not remove or replace the built-in switch. If the position of the
built-in switch moves, it can cause reduced performance, and if the
insulation sheet moves (separator), the insulation may become in-
effective.
Correct Tightening Torque
If screws are too loose they can lead to an early malfunction of the
Switch, so ensure that all screws are tightened using the correct
torque.
In particular, when changing the direction of the Head, make sure
that all screws are tightened again to the correct torque. Do not al-
low foreign objects to fall into the Switch.
Installing the Switch
To install the Switch, make a mounting panel, as shown in the follow-
ing diagram, and tighten screws using the correct torque.
