Precautions
General Information
•
In order to avoid electric shock or
fi
re, 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
fi
re.
•
Use proper wire diameter to meet voltage and current requirements. Using
improper wires or incomplete soldering may cause
fi
re due to abnormal heat
generation.
Installation
Precautions
HE2B
•
M3 nut is inside the rubber cover.
•
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 position-
ing hole in a panel, do not make a hole in the rubber boot, or the waterproof
feature cannot be guaranteed. When the positioning hole is not on the panel,
remove the tab, but do not make a hole in the rubber boot.
•
When tightening the locking ring, secure the
fl
ange 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.

Projection
•
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.

Precautions
HE1B/HE2B/HE3B
•
Applicable wire size is 0.5mm
2
(20AWG) (maximum) / 1 line.
•
When soldering the terminal, solder at a temperature of 260°C within 3
seconds. Use non-corrosive liquid rosin as soldering
fl
ux.

Precautions
HE2B/HE3B/HE1G
•
To ensure the highest level of reliability connect both contacts to a monitoring
device such as a safety relay.
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.
