Info: Make sure enough insulation is stripped so that the inverter’s AC input wire is
fully inserted in the AC terminal block and enough uninsulated wire is still available to
contact with the lightning arrestor wire when using the service entrance connector.
Info: Some readily used service entrance connectors are the Type SX manufactured
by Ilsco (www.ilsco.com), or the Type N manufactured by Thomas and Betts (www.
tnb.com).
