3.3 Connection
■ Connection diagram
Please refer to the connection diagram for wiring.
The polarity of ( ) is the case where a control power supply is DC.
The tightening torque of mounting screw. M3.5：0.7 to 0.9N･m (7.1 to 9.2kg･cm)
< Caution >
Please do not make a wiring change of the input and auxiliary supply in an energization.
Please be sure to work after intercepting a source.
Please do not touch a terminal etc. at the case of cleaning and check.
A fire-damaged accident may be caused by the wiring difference in auxiliary supply or input.
Please be careful of wiring enough. And, check in the place which has combustibles, an inflammable medicine,
inflammable gas, etc. in environment is also dangerous.
When inductive loads (electromagnetic relay, etc.) are connected to output contact, It recommends attaching
diode (or surge killer) etc. near the load.
3.4 Cautions on mounting
State of mounting
There is no limit of mounting position. Mounting instruction can select 35mm width DIN rail mounting and
screw mounting. In screw mounting, please mount with M4 screw. (However, the screw is not attached.
And, please give the mounting torque of a screw as 1.08 to 1.47N･m (11 to 15kg･cm)).
Should establish of side-by-side mutual mount space 5mm over up. A vertical interval should prepare
space 90mm or more in consideration of radiation and a wiring space.
State of wiring
Please separate wiring of input and output and perform consideration to noise. And, please separate from
a line with the power line used as the source of a noise and steep voltage, and current as much as possible.
Please use shielding wire for the bottom of the remarkable environment of a noise.
Conditions of environment
(1)
The range of the temperature and humidity of environment.
Please give temperature and humidity as a next range from operation of each device.
Temperature：-10 to +55℃，Humidity：5 to 90％RH (Non condensing)
(2)
Environment atmosphere
The case has sealing construction. However, be careful of employment under environment with much dust.
Please consult on the occasion of the employment under corrosive gas environment, such as hydrogen sulfide
gas (H
2
S) and chlorine gas (Cl).
