• Supplying any level of power other than specified above 

can damage the unit or the power source.

• Power up characteristics of a power supply for the unit 

must be such a way that the output voltage goes up with-
in operational voltage range of the unit in 5 seconds.

• The power cables and the signal I/O cables for the unit 

must be located separately.

• The power cables, the signal I/O cables and the commu-

nication cables should not be bundled together or placed

ture conditions.

• Do not use the unit in an environment where flammable 

gases are present.  This may result in an explosion.

ply after it was turned off.

 

ENVIRONMENT

• Indoor use.
• Do not install the unit where it is subjected to continuous 

vibration.  Do not subject the unit to physical impact.

• Environmental temperature must be within -10 to +55°C 

(14 to 131°F) with relative humidity within 30 to 90% RH 
in order to ensure adequate life span and operation.

• Mount the unit on a flat and robust plate.
• Bolts torque: 0.3 – 0.4 N·m
• Lamps are omnidirectional.
• The buzzer sound is directional in front of the unit.

 

INGRESS PROTECTION (IP65)

• The IP code is conformable when the unit is mounted ver-

tically, and the control panel cover is locked.  The com-
partment, where connectors are located, is not protected.

• When opening the control panel cover, avoid humidity 

and dust penetration.  Dry and clean it if condensation is 
formed, and close the cover locking tightly.

• In order to protect ingress of water or dust into the bot-

tom compartment, mount the unit correctly on the flat 
plane, and be sure that the gasket does not roll back or 
dust is not on the gasket.

 

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 unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for
