10. OUTLINE
When performing the Voltage Breakdown Test,
Insulation Resistance Test, or any unpowered
electeical test, wait 10 seconds after the power
supply is turned off before removing the housing
cover. Be sure to remove the Short Bar at
terminal “G”. After testing, return the Short Bar
to it’s correct position. Please be sure to use
resistance when discharging.
Screw tightening torque should be 12kgf.cm
(0.88ft-lb) or more, because the G-terminal is
thought as a protective grounding and should
conform to the Safety Requirements.
