Auto (Remote) Starting Of The Unit; Derating For Altitude; Generator Output Connections - Generac Power Systems Magnum Series Operating Manual

AUTO (REMOTE) STARTING OF THE UNIT

Auto mode is used when the unit is started from a location other than the control panel by using a transfer switch.
Auto (remote start) is the normal setting when the unit is being used as a standby power supply. Before putting the
unit in the Auto mode, review the
and information on isolating the generator with a transfer switch if the unit is to be used as a standby power supply.
Refer to Transfer Switch. Then continue with the steps described below:
1. Perform a manual start of the unit at least once to verify that the engine is operating correctly.
If a check of the remote start circuit is desired, remove the wires from the remote start terminal block. Press
2.
the Auto/Manual Mode ( ) button, the LCD window should show "Auto Mode" at the top of the screen.
Attach a jumper wire (minimum 16 gauge) across the two terminals on the remote start terminal block. This
applies a ground to the Power Zone™ Controller to close the starting circuit contacts. The engine should
crank, start and run.
Remove the jumper wire from the remote start terminal block and the engine will stop. Reconnect any nec-
3.
essary wires from the remote start switch (transfer switch) to the remote start terminal block.
Confirm the unit is in Auto mode. The LCD window should show "Auto Mode" at the top of the screen.
4.
Close the main circuit breaker (set to ON (I)).
5.
Secure the unit by closing and locking all access doors.
6.
The unit is now ready for remote starting.
7.
The remote start terminal block provides a connection for installation of a remote start
switch which will allow the unit to be started by a remote dry-contact closure switch.
For location of the remote start terminal block, refer to
Before entering Auto mode, verify that the contacts on any remote switch linked to the
unit are OPEN. If the contacts on a remote switch are closed, the engine will crank
and start when Auto mode is entered. Attach the switch leads to the two unused
terminals on the unit's remote start terminal block.

DERATING FOR ALTITUDE

All units are subject to derating for altitude and temperature; this will reduce the available power for operating tools
and accessories connected to the receptacles. Typical reductions in performance are 2-4% for every 1000 ft (305
m) of elevation and 1% per 10ºF (5.6ºC) increase in ambient air temperature over 72ºF (22ºC).

GENERATOR OUTPUT CONNECTIONS

The unit is equipped with connection lugs, located on the lower portion of the control box behind the lug box door.
The lugs provide connection points for attachment of external loads to the generator. A large decal on the inside of
the connection lug door details the proper connections for selected voltages.
It is HIGHLY RECOMMENDED that only a trained and licensed electrician perform any
wiring and related connections to the generator. Installation should be in compliance
with the National Electrical Code (NEC), state and local regulations. Failure to follow
proper installation requirements may result in equipment or property damage, per-
