Upper category
temperature
Do not exceed the upper category temperatur. 7.2
"Maximum permissible
operating temperature"
Maintenance Make periodic inspections of the capacitors.
Before the inspection, make sure that the power
supply is turned off and carefully discharge the
electricity of the capacitors.
Do not apply any mechanical stress to the
capacitor terminals.

Mounting
position of screw
terminal capacitors
Do not mount the capacitor with the terminals
(safety vent) upside down.

terminals"
Mounting of
single-ended
capacitors
The internal structure of single-ended capacitors
might be damaged if excessive force is applied to
the lead wires.
Avoid any compressive, tensile or flexural stress.
Do not move the capacitor after soldering to PC
board.
Do not pick up the PC board by the soldered
capacitor.
Do not insert the capacitor on the PC board with a
hole space different to the lead space specified.

terminals
The following maximum tightening torques must
not be exceeded when connecting screw
terminals:
M5: 2 Nm
M6: 2.5 Nm
