IMPORTANT
It is important to use low-inductance DC cable routing to help reduce the
risk of voltage oscillations between clusters.
Low-inductance DC cable routing can be achieved by means of positive
and negative cables routed in parallel and as close to one another as
possible, less than 0.3 m (1.0 ft).
Size the DC cable in accordance with UL or applicable agency guidelines.
The voltage drop across the DC cable can be further reduced by using a
bigger cable size because voltage drop is directly proportional to cable
resistance (see Recommended DC-bus Cable Gauge
on page 149).
