Dual Voltage Reconnection - Generac Power Systems NP Series Installation Manual

DUAL VOLTAGE RECONNECTION
NOTE:
Be sure to read "Reconnection for Dual
Voltage: on page 3. Installers must be aware that if
they reconnect the generator for dual voltage AC out¬
put, the generator is not listed per RVIA.
When reconnecting these units for dual voltage,
replace the existing circuit breakers with a single suit¬
ably rated circuit breaker.
RECONNEQION PROCEDURE
NOTE:
Not applicable to Q-40G model.
t.Gain access to the generator panel interior by removing
the generator cover and the front panel (Figure 26).
2. Disconnect stator leads 11 and 33, T1 (red) and T3
(black) from the main circuit breakers CB1 and CB2
(Figure 27). Set aside leads T1 (red) and T3 (black) for
later use.
Figure 27 — Existing
Wiring Connections — 120 Volts
3. Disconnect stator, leads 11 and 33 from the 4-tab terminal
connector (TC).
4. Disconnect stator leads 22 and 44 from the grounding
terminal (GT).
5. Disconnect one of the two ,T2 (white) leads from the
grounding terminal.
6. Remove the existing circuit breakers CB1 and CB2.
Install new appropriately rated circuit breaker.
7. Connect stator leads 11 and 44 to the new circuit breaker
as shown in Figure 28. Also attach leads T1 (red) and T3
(black) to the circuit breaker as shown.
8. Connect stator leads 22 and 33 to the grounding terminal
(GT) as shown (Figure 28).
9. Be sure a neutral lead is installed and routed from the
grounding terminal for connection loads.
10. Routs leads T1 (red) and T3 (black) and the grounded
neutral lead through the conduit clamp and out of the
panel.
11 .Reassemble the panel and generator cover.
Loads may now be connected as follows (Figure 28):
• T3 (black) to Neutral —120 volts
• T1 (red) to Neutral — 120 volts
• T1 to T3 — 240 volts
