Generac 04389-0 - Manual (Page 6)

Only qualified electricians or contractors should
attempt such installations, which must comply strictly
with applicable codes, standards and regulations.
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents
for damage.
• This standby generator set has been factory sup-
plied with a weather protective enclosure that is
intended for outdoor installation only.
• This standby generator set is packaged with an
automatic transfer switch with built in load center.
The combination transfer switch and load center is
pre-wired with a 2 foot and 30 foot conduit. Circuit
breakers for emergency circuit connections are
included.
• This UL listed, 2-pole switch is rated at 100 AC
amperes at 250 volts maximum. This transfer
switch is for indoor use only.
If this generator is used to power electrical load
circuits normally powered by a utility power
source, you are required by code to install a trans-
fer switch. The transfer switch must effectively iso-
late the electrical system from the utility distribu-
tion system when the generator is operating (NEC
701). Failure to isolate an electrical system by such
means will result in damage to the generator and
also may result in injury or death to utility power
workers due to backfeed of electrical energy.
If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage on
the freight bill or affix his or her signature under the
consignor's memo of loss or damage.
If you note loss or damage after delivery, separate the
damaged materials and contact the carrier for claim
procedures.
“Concealed damage” is understood to mean damage
to the contents of a package that is not in evidence at
the time of delivery, but is discovered later.
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have to
run for long periods of time with no operator present to
monitor engine conditions. For that reason, the engine is
equipped with the following systems that protect it
against potentially damaging conditions:
1. Low Oil Pressure Sensor
3. Overcrank
2. High Temperature Sensor 4. Overspeed
There are LED readouts on the control panel to noti-
fy you that one of these faults has occurred. There is
also a “System Set” LED that is lit when all of the fol-
lowing conditions are true:
1. The Auto/Off/Manual switch is set to the AUTO
position.
2. The “Not In Auto” dip switch is set to the OFF
position on the control board.
3. No alarms are present.
1.3 ADDITIONAL GENERATOR
FEATURES
1.3.1 7 KW, 12 KW, AND 15 KW UNITS
The 7 kW, 12 kW and 15 kW air-cooled Guardians
offer additional features that are not factory preset:
1. Remote Start – This allows for remote starting of
the generator by means of the #183 (common)
and #178 (normally open) lines with the
Auto/Off/Manual switch set to AUTO. Closure of
the circuit starts the unit; opening of the circuit
stops the unit. See Figure 1.1.
NOTE:
This function will work only with the unit in the
AUTO mode.
Figure 1.1 – Remote Start/Alarm Options
–Type 14 AWG wire is recommended.
–These options should be wired to the unit by a qualified electrician or
Generac/Guardian Authorized Dealer.
2. Remote/Common Alarm – This allows for an
alarm, light, horn, etc., to activate when any fault
has occurred. Lines #210 (common) and #211
(normally open) provide a “closure” on common
fault, which can be used for 120 volts, 10 amps
maximum. See Figure 1.1.
3. Remote Not Auto – The generator will not auto-
matically start during a utility failure.
