7)
Use a socket wrench to loosen and remove the Positive (+) and Negative (−) cable
connector retaining nuts on the inverter.
8)
Place the Negative (−) cable ring terminal onto the Negative (−) DC terminal.
9)
Place the retaining nut on the terminal stud. Use the socket wrench to make a good, secure
connection.
10)
Recheck and make sure the DC cable fuse is installed in the fuse holder between the
Positive (+) connection for the inverter.
11)
Attach the Positive (+) DC cable to the Positive (+) terminal on the battery. Avoid shorting
the socket wrench and carefully tighten the retaining nut.
CAUTION:
Making an initial connection between the positive cable and the inverter’s
positive terminal may cause a spark. This is normal and is a result of capacitors in the
inverter starting to charge. Because of the possibility of sparking, it is extremely important
that both the inverter and the battery bank be positioned away from any source of
flammable fumes or gases. Failure to heed this warning can result in fire or explosion.
Do not make the positive terminal connection immediately after the batteries have been
charging.
Allow time for the battery gasses to vent to outside air.
12)
Attach the positive cable ring terminal to the Positive (+) DC connector stud on the inverter.
Replace the retaining nut and carefully tighten. Make sure the connection is tight and
secure.
13)
Turn on the inverter.
14)
Wait 30 seconds.
15)
Check to make sure that the LED light above the On/Off switch is on and not blinking.
16)
Check to make sure there are not alarms sounding.
17)
Check to make sure that there are no error messages on the display.
18)
Prior to connecting any appliance to the inverter, make sure the appliance is turned off.
19)
When you have confirmed that the appliance to be operated is turned off, plug the appliance
into one of the two AC outlets on the front panel of the inverter.
20)
Turn the appliance on.
Reverse Polarity
Reverse polarity connection will blow the fuses in the inverter and can permanently damage the
inverter. Damage caused by reversed polarity will void the warranty. Connect battery positive
(+) to inverter positive (red); battery negative (-) to inverter negative (black). Be aware, there will
be a large spark when the last DC connection is made. Be very careful to NEVER connect DC
terminals to the inverter backwards (inverter positive to battery negative). Reverse polarity
connection will cause sparking and may cause fire.
Reverse Polarity Protection
SunRay inverters are internally equipped with replaceable spade fuse protection in case of
inadvertent reverse polarity. In the event of inadvertent reverse polarity the bank/series of
spade fuses will blow to prevent further damage to the inverter. This protection mechanism is
not 100% fail-safe. Reverse polarity, even if inadvertent, will void the warranty of the inverter.
