POINTS OF CAUTION

 

CONFORMITY WITH EU DIRECTIVES

• This equipment is suitable for use in a Pollution Degree 

2 environment and in Installation Category II, with the 
maximum operating voltage 300V.  Basic insulation is 
maintained between the input and output.  Prior to in-
stallation, check that the insulation class of this unit sat-
isfies the system requirements.

• The equipment must be mounted inside a panel.
• Altitude up to 2000 meters.
• 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 conformity.

 

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 – 63 Hz, ≥ 130VA
    24V DC rating: 24V ±10%, ≥ 2.5A

 

GENERAL PRECAUTIONS

• Before you remove the unit from its base socket 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 installation base inside proper housing and 
ventilate it.

• Do not install the base where it is subjected to continuous 

vibration.  Do not subject the unit to physical impact.

• Environmental temperature must be within 0 to 55°C or 

32 to 131°F (0 to 50°C or 32 to 122°F for AC power) with 
relative humidity within 30 to 90% RH (30 to 85% RH 
for AC Power) 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.

• When using M2 power, use a ferrite core close to the unit 

for power line.  Using ferrite core is enough to eliminate 
noises, but turning the cable twice (1 round) as figure be-
low is recommended.

• Be sure to close the terminal cover for safety.

 

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.
