. It is recommended to use the
optional connector with cable for
wiring. ( “ 13 Option Parts” (P.15))
(Note) It is not included for this
product (LS7).
. Because the M12 connector is inside
the signal light, be sure to allow a
sufficient length of cable.

 4 Stackable Tower Construction
What is a 'Stackable Structure'?
The ‘stackable structure’ is a feature which allows the main signal light
unit and the outer cover to be separated with just a single touch.
(Previous signal lights require tools to disassemble, such as removing
screws.)

The 'stackable structure' makes maintainance and inspection easier.

Never disassemble or remove any parts outside the

Procedure for removing the stackable parts

Refer to the procedure below to remove the stackable parts.
To reinstall, follow the procedure in the reverse order.
The following example is for a model without a buzzer included.
The removal procedure is the same for the outer cover or the Optional Parts.( “ 13 Optional Parts” (P.15))
