Four-Lead Reconnectable (Single-Phase) Generator Sets Where Generator

Output Can Be Reconnected For 120 volt or 120/240 volt, 60 Hz,

110 volt or 110/220 volt, 50 Hz

NOTE

When a generator set is reconnected to a voltage different than nameplate voltage, notice should be placed on the unit indicating this change. Decals for this purpose are available from authorized Kohler dealers/distributors.

120- or 110- Volt 2-Wire Configuration

Figure 5-5 (Single Pole)

If the installation requires a 120 or 110 volt, 2-wire system, a single-pole circuit breaker must be used. See Figure 5-5. When connecting stator phase leads together, the output lead (L1) must be sized accordingly.

120- or 110-Volt 3-Wire 2-Pole

Configuration--Figure 5-4

Jumper lead to be placed on line side of circuit breaker. Leads L1 and L2 can either be left as separate leads or can be connected together depending upon which is practical for the given application. Regardless of the number of phase (black) leads used in the application, both circuit breakers must have leads attached to the load side. It is recommended that jumper lead be maintained for all straight 120- or 110-volt systems since it helps balance the load of the generator set.
