• Use crimped and sealed copper ring terminal lugs with 5/16” (.79 cm) hole or compression-type lug

to connect battery cables to DC terminals. Soldered cable lugs are also acceptable.

• Use recommended cable sizes (see page 51) to reduce losses and ensure high performance of FX

(smaller cables can reduce performance and possibly damage the unit).

• Keep cables together (e.g., using a tie-wrap) as much as possible.

• Ensure cables pass through the same knockout and conduit fi ttings to allow inductive currents to

cancel.
