 ENVIRONMENT

• Indoor use
• 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 +70°C 

(14 to 158°F) with relative humidity within 30 to 90% RH 

in order to ensure adequate life span and operation.

 WIRING

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

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.

 INSTALLING THE MODULE

When it is installed on the printed wiring board, land diam-

eter ø1.5 and through-hole ø0.9 are recommended.

 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.

• Do not leave the output terminals shortcircuited for a long 

time.  The unit is designed to endure it without break-
down, however, it may shorten appropriate life duration.

CHECKING

1)  Terminal wiring: Check that wiring is correctly connect-

ed according to the connection diagram.

2)  Power input voltage: Check voltage across the pins.
