Safety Note
Ÿ
Turn off the power before connecting any module or wire. The correct
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.
Ÿ
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 the current surpasses the
maximum ratings, the wiring could overheat, causing serious
damage to your equipment.

Optional
: The switch chassis can also be connected to a known
grounding point for additional safety and protection (grounding wire is
not included)
