3.14 Ground Connection
See Graphic: wc_gr002611
A ground connection (s) is located next to the terminal lugs. The unit
must have this ground lug connected to a good earthen ground for
proper operating safety in compliance with NEC and local standards.
3.15 Convenience Receptacles
See Graphic: wc_gr002611
The generator is equipped with two 120V/240V twist lock receptacles
(l) rated at 50A, and one 120V/240V twist lock receptacles (m) rated
at 30A. The two 120V duplex receptacles (n) are equipped with
ground fault interrupts (GFI). Receptacles do not connect through the
main line circuit breaker. Each receptacle is protected by its own circuit
breaker (h, j, k) which is located directly above it. Power to the
receptacles is available any time the generator engine is running, even
with the main line circuit breaker open.
Note: When the voltage selector switch is in the 480 V / 3Ø position,
voltage at the duplex receptacles is 139 V, and voltage at the 30/50 A
receptacles is 139/240 V. When the voltage selector switch is in the
208 V / 3Ø position, voltage at the 30/50 A receptacles is 120/208 V.
When the voltage selector switch is in the 208 V / 3Ø position, the
voltage can be adjusted with the voltage adjustment rheostat (f) to 240
V / 3Ø. The voltage at the duplex receptacles is 139 V, and voltage at
the 30/50 A receptacles is 139/240 V.
3.16 Remote Run Terminal Block
See Graphic: wc_gr002611
The remote run terminal block (o) is located just to the right of the 120V
duplex receptacles. It provides connection points for installation of a
remote start switch. When it is connected to a transfer switch, it allows
the generator to be used as a standby power supply.
3.17 Panel Door Interlock Switch
See Graphic: wc_gr002611
The customer connection lugs panel access door is equipped with an
interlock switch (q). When the door is opened this switch automatically
trips the main circuit breaker. Voltage to the receptacles will not be cut.
