-
The correct power supply voltage is listed on the product label. Check the voltage of
your power source to make sure that you are using the correct voltage. Do NOT use a
voltage greater than what is specified on the product label.
-
Calculate the maximum possible current in each power wire and common wire. Observe
all electrical codes dictating the maximum current allowable for each wire size. If
current go above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
