Name
Indicates the converter model and ratings. Located
on the side of the converter.
Used to connect the control power input.
These connectors output 24 VDC to the SERVO-
PACK. CN103 and CN104 are equivalent outputs.
It is normally not necessary to connect CN104.
Connect this connector to CN901 on the SERVO-
PACK.
Lights (orange) when the main circuit power sup-
ply is ON and stays lit as long as the internal
capacitor remains charged. Therefore, do not touch
the converter even after the power supply is turned
OFF if the indicator is lit. It may result in electric
shock.
Connect a DC reactor for harmonic suppression.
1 and 2)
