Note : Confirm the outside diameter of the multi-core cable, the connector type
depends on the outside diameter of multi-core cable.
Note : When using ST-M20×1.5, use with gasket GP-M (Type No: GPM20, made by
LAPP).
Note : If you use HS1T as Type 4X
Indoor Use Only

Note : To unwire the terminals, disassemble the product in the following order:
turn off the power → loosen connecter B → remove the terminal cover →
remove the waterproof gasket from connecter A* → loosen connecter A
* Please remove the water-proof gasket carefully with tools such as tweezers.
Be careful when removing the gasket as damages may affect its waterproof
properties. Also, loosening connecter A without removing the gasket first may
damage the cable and provoke connection issues. Please make sure you
re-insert the waterproof gasket properly into connector A when re-assembling
the product.

CAUTION
• Make sure not to lose any screw when
removing the terminal cover from the
switch.
• Please make sure the cable is insterted
deep enough into the terminal cover so
that the waterproof gasket can tighten
he cable sheath completely and ensure
its waterproof functions.
• Make sure you always tighten connecter
A before connecter B, otherwise the
wires which connect the terminals might
get twisted or might break, and this
might also damage the terminal ports.
• When tightening the connecters, only
use a tightening torque that is approved by the connecters' manufacturer to
ensure waterproof properties of the product.
• Do not pull or twist the cable with excessive force, otherwise you might damage the
wires inside of it.
Use a connector with a degree of protection IP67.

Connecters' mounting method
Correct
The wire is inserted
deep enough
between the clamps
Incorrect
The wire insula ion
sheath is in contact
with the clamps
CAUTION
• When using wire with insulation
diameter of Φ2.0mm or less, do not
insert the wire too deep where the
insulation inserts into the spring clamp
opening. Otherwise conductive failure
will be caused. Make sure that the
wire insulation is stripped 8 to 9 mm
and the wire is inserted to the bottom.
• Please only connect one wire per
terminal port (according to the general
requirements section (13.1.1) of
IEC60204).
