POINTS OF CAUTION

 CONFORMITY WITH EC DIRECTIVES

• This equipment is suitable for use in a Pollution Degree 

2 environment and in Installation Category II, with the 
maximum operating voltage of 300V.

  Reinforced insulation is maintained between signal input, 

output and power input, basic insulation is between the 
input and DC output.  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  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.

• In order to enable the operator to turn off the power input 

immediately, install a switch or a circuit breaker accord-
ing to the relevant requirements in IEC 60947-1 and IEC 
60947-3 and properly indicate it.

 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, 50/60 Hz, approx. 6.5VA
  24V DC rating: 24V ±10%, approx. 3W
  110V DC rating: 85 – 150V, approx. 3W

 GENERAL PRECAUTIONS

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

supply and input signal for safety.

• Be sure to put the terminal cover on while the power is 

supplied. 

 ENVIRONMENT

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

install the unit inside proper housing with sufficient ven-
tilation.

• 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.

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

bles, etc.

 REQUIREMENTS TO ENSURE IP66

• Observe  the  designated  panel  cutout  size  (W92 

×

  H45 

mm).

• The watertight packing included in the product package 

must be placed behind the front cover.

• Both  mounting  brackets  must  be  fastened  tightly  until 

they hit the panel.

• Confirm visually that the packing is not contorted or ex-

cessively run off the edge after installation.

 WIRING

• Make  sure  for  safety  that  only  qualified  personnel  per-

form the wiring.

• Do  not  install  cables  (power  supply,  input  and  output) 

close to noise sources (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 sat-
isfying complete performance described in the data sheet.
