¡
When installing the power supply with your unit, ensure that the
input FG terminal of CN1 or mounting hole FG is connected to
safety ground of the unit.
6 Option and Others
6.1 Outline of options
¿
-C
-
Option -C models have coated internal PCB for better moisture
resistance.
¿
-G
-
Option -G models are low leakage current type.
-
Differences from standard versions are summarized in Table 6.1.

Ripple Noise
*
This is the value that measured on measuring board with capaci-
tor of 22μF at 150mm from output connector.
Measured by 20MHz oscilloscope or Ripple-Noize meter (Equivalent
to KEISOKU-GIKEN:RM-103).
