Safety Precautions••Do not install the interlock plug unit in places subject to oil orwater. Electric shock or fire hazard may be caused if the inter­lock plug is operated when the plug part is contaminated withoil or water.
••Interlock plug units are used to ensure the safety of operators
who carry the plugs. Provide only one plug to a guard. Other­wise the hostage control function is lost, endangering theoperators. Ensure complete safety management so that thefunction is maintained.

••In order to avoid electric shocks or fire, turn power off before installation, removal, wire connection, maintenance, orinspec­tion of the interlock plug unit.
••Do not disassemble or modify the interlock plug unit. Also do
not disable the function of interlock plug unit intentionally. Oth­erwise a malfunction or an accident may occur.

Instructions••The plug of HS2P interlock plug units resemble the plug of
HS1P interlock plug units, however, these plugs are not inter­changeable. Do not use the plugs of other types, otherwise
the interlock plug units will be damaged. The plugs can bedistin­guished with the handle color.

HS1P: black
HS2P: aluminum color

When mounting the HS2P interlock plug on a panel, alignthe recess on the panel and the projection of the anti-rotat­
ing ring as shown below.

Using locking ring wrench OR-12 sold separately, tighten
the locking ring to a torque of 1.8 to 2.2 N·m. Do not tighten
with excessive force, otherwise the interlock plug will bedam­aged.

Note 1: When using the main circuit on AC, connect emergency
stop switch to Line, and interlock plug unit to Neutral.
Note 2: When using the main circuit on DC, connect to the + linewith emergency stop switch first followed by the interlock

Recess••Do not store the interlock plug units in a dusty, humid, ororganic-gas atmosphere. Also avoid direct sunlight.
••Make sure that the interlock plug unit is not energized whenremoving or installing the plug (after operating the emergency
stop button shown in the circuit example shown below). Do
not start or stop the machine by plug removal/installation,other­wise the interlock plug unit may fail.

••Use an insulation tube on the crimping terminal.
••When using stranded wires, make sure that loose wires donot cause short circuit. Also, do not solder the terminal toprevent loose wires.

Mounting Panel Thickness and Gaskets

Applicable Wire Size

The HS2P interlock plug is supplied with gaskets (1.5-mmthick × 2 and 0.5-mm-thick × 1) and an anti-rotation ring.
Adjust the number of gaskets depending on the mounting
panel thickness as shown in the table below. Do not use
other combination of gaskets, otherwise the interlock plug
will be damaged.
