General Information for Enabling Switches
Safety Precautions
• In order to avoid electric shock or fire, turn power off before installation, removal, wire connection, maintenance or inspection of
switch.
• Follow specification when installing. Improper electrical load may
damage switch, cause electric shock, or fire.
Installation Precautions
HE2B
• M3 nut is inside the rubber cover.
Panel
Thickness (6mm)
Mounting Screw
HE2B/HE3B
• A change in internal air pressure may cause the rubber boot to
expand and shrink on an enabling switch that has the rubber boot
sealed. This may affect the performance of the switch. Periodically
check to ensure that the enabling switch is operating correctly.
Wiring Precautions
• Use proper wire diameter to meet voltage and current requirements.
Using improper wires or incomplete soldering may cause fire due to
abnormal heat generation.
B
Safety Products
• If the panel is not level when mounting an enabling switch, the
waterproof feature cannot be guaranteed.
HE3B
• The rubber boot has a tab to be used for orientation. When making a
positioning hole in a panel, do not make a hole in the rubber boot, or
the waterproof feature cannot be guaranteed. When the positioning
hole in not on the panel, remove the tab, but do not make a hole in
the rubber boot.
• When tightening the locking ring, secure the flange to prevent the
enabling switch from rotating. In applications where the enabling
switch is to be rotated, mount the switch in a recess on the panel as
shown.
HE1B/HE2B/HE3B
• Applicable wire size is 0.5mm (maximum) / 1 line.
• When soldering the terminal, solder at a temperature of 260°C within
3 seconds. Use non-corrosive liquid rosin as soldering flux.

HE1B/HE2B/HE3B
• When installing the enabling switch ensure that it cannot be accidently activated. For example, a protrusion from a teaching pendant
could cause the enabling switch to be activated by the weight of the
teaching pendant.
