a. L = line or phase, N = neutral, G = ground
b. An imbalance of AC input currents may exist on the three-phase power source feeding the
array, depending on the configuration. The customer's electrician must be alerted to this
possible condition to balance the phase-by-phase loading conditions within the customer's
data center.
