R0■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in the air,install the module inside proper housing with sufficientventilation.
• Do not install the module where it is subjected to continuous vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within 0 to 55°C (32to 131°F) with relative humidity within 80% RH in orderto ensure adequate life span and operation.

R13) Tighten screws using the mounting holes to fix the module on a wall.

■ WIRING• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■ AND ....
• The module is designed to function as soon as power issupplied, however, a warm up for 10 minutes is required
for satisfying complete performance described in the datasheet.
