CAUTION
*1: When performing the Insulation Resistance Test or the
Withstand Voltage Test, please obey the following
caution.
• Following the relevant test, wait for more than 10
seconds after the power supply has been turned off
before removing the cover.
• Remove all wires from terminals before testing.
• When the power terminal has a lighting protector
(optional code A), remove the short bar at the ground
terminal.
• After testing, be sure to discharge by using a resis-
tance and return all wires and the short bar to its
correct position.
• Screws must be tightened to a torque of 1.18 N-m or more.
• After closing the cover, the power supply can be restored.
