Note : In case of using external noise filter, capacitance between input and terminal might be increased. When
testing withstand voltage between input and output, there is a possibility of exceeding withstand voltage between
output and terminal (1.5kVAC). If the voltage between output and terminal is exceeding 1.5kVAC, the
external capacitor is required to place across output and . It can decrease the voltage between output and
terminal. On the other hand, no need to check the voltage in case of output and terminal is shorted.
6-14. Remote ON/OFF Control
Remote ON/OFF control (CN53) function is provided. Using this function allows the user to turn the output
on and off without recycle of AC input. Remote ON/OFF can be controlled by the voltage RS/+RO
terminal and -R terminal. +STB terminal (pin No.6) - +RS terminal (pin No.4) and -STB terminal (pin No.5) -
-R terminal (pin No.3) are connected by short piece (connector) at shipment. The short piece must be removed
to perform remote ON/OFF control function. Remote ON/OFF circuit is in the secondary side of the power
supply and it is isolated from output circuit. Never connect to the Primary side.
