2. Wiring for field power supply must be rated 75 C minimum. Use cop-
per, copper-clad aluminum, or aluminum conductors. Maximum in com-
ing wire size for each terminal block is 500 kcmil.
3. Terminal blocks TB3, TBX1, and TBX2 are for external field control con-
nections. Control connections are to be Class 1 wiring.
4. Field-supplied components (IFC, LLS-A1, and LLS-A2) must have a
maximum sealed coil rating of 30 va each (0.25 amp at 120 vac,
13 amp at 230 vac). AHMS IFC-AUX must have minimum pilot duty
rating of 400 va each (3.4 amps at 120 vac, 1.8 amps at 230 vac) each.
5. Replacement of factory wires must be with type 105 C wire or its
