panel of a metal enclosure.

• The actual installation environments such as panel con-

figurations, connected devices and connected wires may
affect the protection level of this unit when it is integrat-
ed 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 CE conformity.

• 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 RANGE

• Locate the power input rating marked on the product and

confirm its operational range as indicated below:

24V DC rating: 24V ±10%, approx. 90mA

 

GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power 

supply and input signal for safety.

 

ENVIRONMENT

• Indoor use.
• When heavy dust or metal particles are present in the

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.
