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.

Example of wiring Diagram realizing Safety Category
S1: HS5L-VB4 Safety Switch with Solenoid
S2: Starting Switch (HW Series Momentary)
S3: Unlocking Enabling Switch
S4: Safety limit Switch
ESC: Outside start condition
K3, 4: Safety Contactor
F1: Outside fuse of safety relay module at power supply line
Note: Use he monitoring device(Safety relay module) provided he capavility to
detect a cross short circuit. The insulation of the cable has to withstand
environmental influences. If a control device other than he one shown in the
draft is used, the used control device has to be equipped with a cross short
circuit monitor.

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 connect-
er 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
he wires inside of it.

1. Loosen connecter A and connecter B, and insert the cable into these pieces in the
following order :
connecter B → waterproof gasket → connecter A.
Do not tighten the connecters yet.
2. Remove the terminal cover from the switch
and insert the cable into the cover.
3. Wire the terminals.
4. Tighten connecter A into the terminal cover.
Fix the terminal cover back into its original
position. Tighten connector B.
