Socket：Standard is M3×8 (dated washer) screw. M3×8 double washer type screw can support by designation,
too. In designation of a M3×8 double washer type screw, please designate as socket type FW11-W at the caseof an order.

2.2 Name and function(1) RUN LED
The operation function of this product is indicated by LED (green).
The LED lights up at normally. When abnormal, it blinks in response to symptoms.
(For details, refer to 4.4 Switch and Display Specification)(2) Setting switch
Set the communication address to be used for communication.
Set the communication address (1 to 89) separately with 10 digit switch and 1 digit switch.
This setting is read at power on. When setting is changed while power is being applied, the new address
becomes valid by soft reset with the reset switch.

2.3 Cautions on mounting
The environmental conditions of installation space. Please select indoors without low mechanical vibration,
dust, and corrosive gas.
There is no limit of a mounting position. A mounting instruction can select 35mm width DIN rail mounting
and screw mounting. In screw mounting, please install with M3 screw or M4 screw. (However, the screw is
not attached. The tightening torque of a screw, M3：0.45 to 0.60N･m，M4：1.00 to 1.30N･m)
The interval of FW11 and FW11 does not have designation.
Please consider radiation and wiring space and separate more than 100mm of the space above and below.
(Reference of 2.4 section.)
Please secure the space distance of a terminal and a metal panel 10mm or more.
