Site Configuration for AC Power
The following information is not required, but may save time
and effort implementing this configuration when installing the
system.
Use the following information to configure your site:
Tap into the main AC power source of the building consisting of
208 to 220, 380 to 415 volts AC, 50/60 Hz.
Connect the power through a one-to-one or step-down
transformer to the correct voltage for the system.
Important recommendations about wiring
•
Make certain that the wire used for the neutral is the same
size as the hot leads or larger.
•
Do not rely on conduit for the ground; always use at least
one wire for the ground-the more strands the better.
•
Use the same lengths of wire for the phase conductors, the
neutral, and the ground.
•
It is extremely important that the neutral and ground be
connected only at the transformer using an X-O bond.
NOTE
The following requires that you:
1
Use a wire and not a conduit for the safety ground conductor.
2
Use the same size wire for all the neutral and ground as is used
for the phase conductors.
3
Bond the neutral and the ground wires together at the
transformer, and not at the breaker box or anywhere else.
