M Customer supplied equipment. Install any protective device external to the SyncPro in series in this
circuit as shown. Logic must be that contact is closed if running is permitted.
N FLC and TC are optional customer supplied inputs which are jumpered to terminal blocks if not used.
O Contact rating is 60 amp Make, 10 amp Break (inductive) – 10 amp continuous at 120V AC (A600)
P Refer to instruction manual for tap selection guidelines on RF1andRF2resistors.
Q Analog card switch settings are:
R Customer to take ground wire to ground bus (earth ground).
S Ground at bottom left hand mounting screw for rack or grounding bar.
T Line 1 to Line 2 voltage reference and Line 3 current reference must be maintained for proper
operation of the phase angle transducer.
U Wiring supplied on enclosed assembly only (1901-AADC10) for the open frame units. The customer
must supply these wires in addition to mounting the illuminated push button. DTAM, STAM cable
(1747-C10) and illuminated push button are supplied loose on open frame assemblies (1901-ANDC10).
V Output rating is 30 amp Make, 3 amp Break (inductive) – 3 amp continuous at 120V AC.
