tions must be in compliance with all applicable codes.

2. Wiring for field power supply must be rated 75 C minimum. Use cop-

per, copper-clad aluminum, or aluminum conductors. Maximum
incoming wire size for each terminal block is 500 kcmil.

3. Terminal blocks TB3 and TB4 are for external field control connec-

tions. Control connections are to be Class 1 wiring.

4. Field-supplied components (IFC, LLS-A, and LLS-B) must have a maxi-

mum sealed coil rating of 30 va each (.25 amp at 120 vac, .13 amp at
230 vac). AHMS IFC-AUX must have a minimum pilot duty rating of
200 va (1.7 amps at 120 vac, 0.9 amps at 230 vac) each.

5. Replacement of factory wires must be with type 105 C wire or its
