Main AC Wiring

NOTE: Main AC wiring must be in accordance with local
jurisdiction and codes.
Strip the insulation off the wire ends. Do not
1.
remove excessive insulation.
Remove the two cap plugs located behind the
2.
breaker door and to the right of the Main Breaker.
Loosen the lugs of the Main Breaker through the
3.
access holes.
Insert a power wire (E1 or E2) through the opening
4.
in the back cover and into the bottom lug. Torque to
the proper specification.
NOTE: There are three screws inside the top of the
breaker panel (behind the breaker door). Removing
these screws will allow the entire breaker box to be
carefully pulled out. When reinstalling, be certain that the
tabs on the bottom lock into place.
Connect the Neutral wire to the Neutral Lug if
5.
applicable. Torque to the required specification.
See Table 6.2.
Connect the Ground wire to the Ground Lug and
6.
torque to the required specification. See
NOTE: See Figure
installations that require the neutral to be bonded to the
ground, this is to be done on the customer connections
terminals inside the generator. Connect a suitably sized
wire from the neutral bar to the ground bar. This is
normally required when the generator is the source in a
separately derived system. It is not required when the
generator is a backup source in a utility supplied
electrical system with a 2-pole transfer switch.
NOTE: Torque all wiring lugs, bus bars and connection
points to the proper torque specifications. Torque
specifications for the Main Line Circuit Breaker (MLCB)
can be found on a decal located on the inside of the Main
Line Circuit Breaker Door.

Load Shed Functionality

The Synergy product Transfer Switch includes an
Overload Prevention Control Board (OPCB) to shed
critical loads.
The OPCB, commonly referred to as the Load Shed
Board, has "Fast Load Shed" capability, which effectively
prevents large loads from stalling the engine. ALL
LOADS GREATER THAN 10 kW OR 2 HP (MOTORS)
MUST BE CONNECTED TO THE OPCB. If natural gas is
the selected fuel type, then all loads greater than 9kW
must be connected to the OPCB. Examples of a large
load are a 3T air conditioner, 3 HP well pump, 3 HP sump
pump, etc.
When the generator senses the application of a large
load (greater than 10 kW or 2HP) while the engine is at
low speed, the load is instantly shed (within milliseconds)
and the engine is instructed to run at 3600 RPM. This
action prevents stalling of the engine. The loads are then
reapplied when the engine is back up to speed. Normal
loads take about six seconds. Large loads, such as an air
conditioner, have specially designated connections on
the OPCB, and are only reapplied after five minutes (to
protect the air conditioner motor).
6.2. See the Transfer Switch Owner's Manual for a complete
description.
Automatic Voltage Regulator
(AVR) Cooling Fans
The system is equipped with two fans to cool the AVR
electronics. The primary fan is powered by AC during
operation. The secondary fan is powered by 12V DC
through the controller. The fans are monitored during
operation and if a failure occurs, an alarm is displayed.
The secondary fan continues to operate for up to one
hour after the generator is shut down. Proper cooling
must occur before removing either battery connections or
7.5 amp fuse for maintenance or other service activity.
Moving Parts. Avoid AVR fan housing for one
hour after generator shutdown. Fan operates
even if fuse is removed. Rotating fan blades
could result in death or serious injury.
NOTE: The AVR cooling air inlet includes a filter. Verify
the filter is installed and properly seated at time the unit is
installed. Check the filter at regular maintenance intervals
to verify proper airflow. See the Maintenance section of
the Owner's Manual for details.
