figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated 
in a panel system.  The user may have to review the CE 
requirements in regard to the whole system and employ 
additional protective measures to ensure the CE conform-
ity.

• Install lightning surge protectors for those wires connect-

ed to remote locations.  Choose a surge protector with its 
maximum surge voltage 40V or less between lines.  Rec-
ommended M-System model: MDP-D24.

 

POWER INPUT RATING & OPERATIONAL RANG

• Locate the power input rating marked on the product and 

confirm its operational range as indicated below:

air, install the unit inside proper housing with sufficient 
ventilation.

• 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.

 

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 
satisfying complete performance described in the data 
sheet.
