7.1 Cautions for mounting
In order to avoid factors of breakdown or malfunctions, read and understand the below contents
before using. For installing, use within the range of general specifications. Especially notice and
keep the below conditions.
7.1.1 Environment for using
1) Use in the place where the ambient temperature is the range of -10 to +50 degree C and the
ambient humidity is the range of 30 to 85%RH (at 25 degree C non-condensing)
2) Do not use the unit in the following environments.
・
Where inflammable or corrosive gas might be produced. Where the unit will be exposed to
excessive airborne dust or metal particles. Where the unit will be exposed to water, oil or
chemicals.
・
Where direct vibration or shock might be transmitted to the unit, and where the unit will be
exposed to direct sunlight and where water might wet the unit.
・
Where high-voltage line, high-voltage device, power line, power supply device or the device
with sending part such as amateur radio are existed, or large switching surge is occurred.
(Keep input/output line away from power/high-voltage line at least 100mm or more.)
・
Where organic solvents such as benzene, paint thinner, alcohol, or strong alkaline solutions
such as ammonia or caustic soda might adhere to the product
・
High altitude where exceed 2000m.
・
This product is not waterproof specification. When use in outdoor, give waterproof measures
as putting in a plastic case etc.
7.1.2 Power supply
1) Use twisted wire for power supply cable.
2) Separate power supply from power supply for devices and make the protective circuit. (Fuse
etc.)
3) Against the superimposed noise on power supply line, we recommend to reduce the noise by
using insulated transformer or noise filter.
4) When grounding, make it dedicated and the grounding connection should have a resistance of
less than 100 ohms. Do not share a ground with other earth line.
5) Make power supply on/off by taking out and putting in the connector.
7.1.3 Mounting
1) Do not bring it close to a radio and television. It may cause poor reception.
2) Where the place there is a broadcasting station or radio station and radio wave from there is
strong, this unit may not be able to use.
3) This unit uses 2.4GHz-width wave to transmit data, if some devices using the same frequency
are existed, interference might occur and not be able to communicate.
4) In order to make the wireless performance better, pay attention to the below items.
・
Mount the unit as high as possible.
・
Connect 2 of the antenna and the mounting direction is vertical for the ground.
・
Antenna should be keep away from metal board. If antennas are mounted inside the control
board, the wireless performance will decrease.
・
Keep away from the place or line that noise might occur.
・
Mount in the place where radio wave condition is good refer to field intensity monitor.
・
When you use several channels in the same communication area, check if there is no
influence each other.
