POINTS OF CAUTION

 

CONFORMITY WITH EU DIRECTIVES

• This equipment is suitable for Pollution Degree 2 and In-

stallation Category II (transient voltage 2500V).  Rein-
forced insulation (signal input or output to power input: 
300V) is maintained.  Prior to installation, check that the 
insulation class of this unit satisfies the system require-
ments.

• Altitude up to 2000 meters.
• The equipment must be mounted inside a panel.
• The equipment must be installed such that appropriate 

clearance and creepage distances are maintained to con-
form to CE requirements.  Failure to observe these re-
quirements may invalidate the CE conformance.

• The actual installation environments such as panel con-

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.

 

POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and 

confirm its operational range as indicated below:

    100 – 240V AC rating: 85 – 264V, 47 – 66 Hz,
     

 

 

 

        ≤ 7VA at 100V AC

     

 

 

 

        ≤ 10VA at 200V AC

     

 

 

 

        ≤ 12VA at 264V AC

    24V DC rating: 24V ±10%, ≤ 4W
    110V DC rating: 85 – 150V, ≤ 4W

 

GENERAL PRECAUTIONS

• Before you remove the unit from its base 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 -5 to +55°C     

(23 to 131°F) with relative humidity within 10 to 85% RH 
in order to ensure adequate life span and operation.

• Be sure that the ventilation slits are not covered with ca-

bles, etc.

 

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.

• With voltage output, do not leave the output terminals 

shortcircuited for a long time.  The unit is designed to 
endure it without breakdown, however, it may shorten ap-
propriate life duration.
