Warning
1. Connect load before connecting with power
source.
2. In the case of induction load or lead wire ex-
ceeding 5 m long, the following contact protec-
tion box should be used. It may lead to dam-
age to a switch.

Mounting/Piping
Warning
1. When changing piping by hand, hold body.
Electrical wire must not be subjected to exces-
Brown
sive force.
It may cause a malfunction or damage.
2. Do not drop nor apply excessive force.

Pressure Source
Warning
1. Do not use with corrosive gases or fluids.
2. Never use in an environment where flamma-
ble fluid or gas is used. Since this is not an
explosion-proof construction, it may lead to an
explosive disaster.
3. Avoid use in vacuum applications.
Switch may be imploded.
Pressure Setting
Warning
1. Scale of switching set display is the set value
at the pressure drop.
2. When detecting ON-pressure signal, note that
set pressure on scale plate plus ON-OFF differ-
ential (Hysteresis) will be ON-pressure signal.
3. Pressure display on the scale plate is just as a
reference guide. For an accurate setting,
measure it by pressure gauge.
Operating Environment
Warning
1. Avoid using a switch in a magnetic environ-
ment. It may cause a malfunction.
2. Do not use in such an environment, where
water or oil is splashed. Since it is the open
type construction, if water or oil make an
ingress into the internal parts, the electric
circuit will be corroded and may result in a
malfunction or damage.
3. Avoid vibration. Vibration may cause malfunc-
tion or may cause setting to be incorrect.
