NOTE: Voltage to terminals LL1 and LL2 comes from a control trans-
former in a starter built to Carrier specifications. Do not connect an
outside source of control power to the compressor motor starter (ter-
minals LL1 and LL2). An outside power source will produce danger-
ous voltage at the line side of the starter, because supplying voltage
at the transformer secondary terminals produces input level voltage
at the transformer primary terminals.
