• Use a surge absorber to absorb the lightning surge voltage and the abnormal voltage from the power
input line.
• The following table gives the recommended surge absorber specifications.
Note 1. Refer to the catalogs from the manufacturer for how to use.
2. The surge current tolerance is the value for the standard impulse current of 8/20
μ
s. For a greater pulse
width, reduce the current or change the surge absorber to the one with a higher capacity.
3. Select a CSA-certified product when you use a surge absorber.
