4) Installation procedure and method
① When installing metal head type button, insert the operation head
into the mounting hole from the front of the panel, then screw it into the
base from the back of the panel. Tighten the fixing screws at both ends
evenly (as shown in Figure 4). Do not overtighten the screws, the torque
should not exceed 0.25N·m. If the button is jammed after installation, adjust
the two fixing screws on the base and make sure they have the same
tightness.
②Before installing plastic head type button, remove the base first (insert
a screwdriver into the hole on the base and pry it up, as shown in Figure 5).
Tighten the nuts with a torque of 1.2N·m~1.8N·m.

buttons with cases, there are two
Φ
21mm cable holes on both sides of their bottom covers. Before
installation, user should perforate the cable hole as needed (do not use too
much force). If IP40 is required for overall enclosure protection, user should
pay attention to the protection of the cable holes and the screw holes on
bottom cover. The cable holes can be protected by using cable connectors
with matching specifications or other effective measures. The tightening
torque for the installation of button box case should not exceed 1.2N·m.
