LB/LBW Series
• Turn off the power to the LB/LBW series before installation, removal,
wiring, maintenance, and inspection. Failure to turn power off may
cause electrical shocks or re hazard.
• To avoid burning your hand, use the lamp holder tool when replacing
the lamps.
• For wiring, use wires of a proper size to meet voltage and current
requirements. Solder correctly according to the instructions in
“Wiring” and “Notes on Terminal Cover.” Improper soldering may
cause overheating and create a re hazard. Also, when using tab
terminals, use receptacles of appropriate size.
Wiring
1) Solder the terminals at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu type is recommended when using leadfree
solder. When soldering, do not touch the LB series with the soldering
iron. Also ensure that no tensile force is applied to the terminal.
Do not bend the terminal or apply excessive force to the terminal.
2) Use non-corrosive liquid flux.
Terminal Cover
Solder/tab terminal
Insert the terminal cover into the contact block with the TOP markings
on the contact block and the terminal cover in the same direction.
Note: When wiring, insert the lead wires into the terminal cover holes
before soldering.
After wiring, the terminal covers cannot be installed.

Operating Environment
• Do not use the LB/LBW series where corrosive gases exist or under
an environment exceeding the operating temperature and humidity
ranges. Otherwise, damages due to contact failure or change of
surface color may occur.
• Major parts of the switch are plastic. Scratches or damages may
occur when scraped with a sharp object or applied with excessive
load or shock. Note that this may cause operation and appearance
failure of the operator and bezel.
• Adherence of detergent, cutting oil, or special chemicals to the switch
may result in operation failures and appearance failures such as
change of surface color.
Handling
Contacts (micro switch)
When using NC (normally closed) and NO (normally open) contacts
of the same microswitch, avoid connections of different voltages, or
connections of different types of power supplies. Failure to observe this
instruction may cause a short-circuit.
Protection against oil (IP65)
The LB series has been tested according to JIS C 0920: Appendix 1 by
using water insoluble cutting oil Class N3, No. 8 (JIS K 2241) to prove
that the switches will not be damaged by oil drops or splashes. This
may not apply to special types of oils. Contact IDEC for details.
Removing and Installing the Contact Block
1) Turn the locking lever on the contact block in the direction opposite
to the arrow on the housing. Then the contact block can be removed.
2) Insert the contact block with the TOP markings on the contact block
and the operator placed in the same direction. Then lock the units,
turning the locking lever in the direction of the arrow.
Note: When removing/installing the contact block, or when using the contact
block alone, do not apply excessive force on the actuator. Deformed
actuator may affect contact operation.
