Safety Note
Turn off the power before connecting any module or wire. The correct
Ÿ
power supply voltage (48 – 57 V DC) is listed on the product label.
Check the voltage of your power source to make sure that you are
using the correct part. Do NOT use voltage greater than 48 – 57 V
DC, as specified on the product label.
Calculate the maximum possible current in each power wire and
Ÿ
common wire. Observe all electrical codes dictating the maximum
current allowable for each wire size. If the current surpasses the
maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
