3. Open hinged control panel doors. Connect lead
from terminal 63 to. correct terminal for voltage
desired. These terminals are labeled H2, H3, H4,
H5 and H6. See Figure 16.
Close front panel and secure with 1/4 turn
fasteners.
Connect load wires to generator leads.

Preceding instructions do not apply to models with a 347/600
voltage (designated 9X); this connection is made at the factory. The
installer, must only connect load wires.

3 Phase, 4 Wire, Wye Connected Set; 12 Lead: The 3
phase, 4 wire set produces line to neutral voltage and
line to line voltage. The line to neutral voltage is the
lower voltage as noted on the unit nameplate, and the
line to line voltage is the higher nameplate voltage.
For 3 phase loads, connect separate load wires to
each of the set terminals L l , L2 and L3. Single phase
output is obtained between any two 3 phase ter-
minals.

Theterminal marked LOcan begrounded. For 1 phase
loads, connect the neutral (white) load wire to the LO
terminal. Connect the black load wire to any one of
the other three terminals—L1, L2 or L3. Three
separate 1 phase circuits are available, with not more
than 1/3 the rated capacity of the set from any one
circuit.
If using 1 phase and 3 phase current atthesametime,
use care to properly balance the 1 phase load, and not
to exceed rated line current.
Figure 18 shows load connections for 120/208 voltage. Other
voltages are available from either parallel wye or series wye
illustration in Figure IS.

CONNECTING LEAD FROM TERMINAL 63
120/240 Volt, 3 Phase, 4 Wire Delta Connected Set; 12
Lead: The 3 phase Delta connected set is designed to
supply 120- and 240 volt, 1 phase current and 240 volt,
3 phase current, Figure 17. For 3 phase operation,
connect the three load wires to generator terminals
L l , L2 and L3—one wire to each terminal. For3phase
operation the LO terminal is not used.
For 120/240 volt, 1 phase, 3 wire operation, terminals
L l and L2 are the "hot" terminals. The L0 terminal is
the neutral, which can b'e grounded if required. For
120 volt service, connect the black load wire to either
the L l or L2 terminal. Connect the neutral (white) wire
to the L0 terminal. Two 120 volt circuits are available.
Any combination of 1 phase and 3 phase loading can
be used at the same time as long as no terminal
current exceeds , the NAMEPLATE rating of the
generator. If no 3 phase output is used, usable 1 phase
output is 2/3 of 3 phase KVA.
