RV, or remote home. To get the most out of your PROwatt 250, it must be installed and used properly. Please read the installation and operating instructions in this manual carefully before installing and using your PROwatt 250. -
Page 4: Prowatt 250 Output Waveform
Figure 1. PROwatt 250 - Principle of Operation 2.2 PROwatt 250 output waveform The AC output waveform of the PROwatt 250 is called a “quasi-sine wave” or a “modified sine wave.” It is a stepped waveform that is designed to have characteristics similar to the... - Page 5 This waveform is much superior to the square wave produced by many other DC to AC inverters. The modified sine wave produced by the PROwatt 250 is de- signed to have a RMS (root mean square) voltage of 115 volts, the same as standard household power.

(in watts) by 10 (by 20 for PROwatt 250/24V) to obtain the current (in amperes) the power source must deliver. Example: Load is rated at 120 watts. Power source must be able to deliver: 120 ÷ 10 = 12 amps (or 6 amps for PROwatt 250/24V) -

12 volts (24 volts for PROwatt 250/24V). The PROwatt 250 will not operate from a 6 volt battery (12 volt for PROwatt 250/24V) and will be dam- aged if connected to a voltage source above 16 volts (32 volts for PROwatt 250/24V). - Page 8 #270-341 are suitable. For permanent installation, use heavy-duty ring tongue or locking fork/spade terminals. 4) Power to the PROwatt 250 can be controlled by a switch in- serted in the circuit between the power source and the PRO- watt 250. Use a switch rated at a minimum of 12V/25A con- tinuous current, such as Radio Shack #275-704 for the 12V PROwatt 250.
- Page 9 The case of the inverter is connected to ground conductor of the AC output cord and to the negative side of the DC input. The PROwatt 250 should not be used with positive ground vehicle electrical systems.

90ºC. It will restart once it cools off. CAUTION: PROwatt 250 CASE GETS HOT The case of the PROwatt 250 acts as a heat sink, dispersing in- ternally generated heat. When the PROwatt 250 is operating at high power levels (above 100 watts) for extended periods, the case will get hot. -
Page 15: Battery Operating Time
In most cases the PROwatt 250 can be left connected to the battery when it is not in use since it draws so little current. If the vehicle will not be used for several days, disconnect the PROwatt 250 from the bat- tery. -

10.7 volts (21.5V for PROwatt 250/24V). This indicates that the battery requires charging. The user should stop operations at this time since the PROwatt 250 will shut down automatically shortly afterwards. If the low battery alarm sounds when the battery is fully charged, follow the steps for remedying lack of power output in section 5.2 (Troubleshooting Guide) of the manual. -

Position the PROwatt 250 as far as possible from the televi- sion, the antenna and the antenna cables. Use an extension cord to move the PROwatt 250 away from the television. b) Adjust the orientation of the PROwatt 250, the antenna ca- bles, and the TV power cord to minimize interference. - Page 18 Cigarette lighter circuit fuse Check vehicle fuses, replace open (blown). damaged fuse. Poor connection or Repair connections and use inadequate wiring between heavier gauge wire (3.3mm battery and cigarette lighter. or 12 AWG is sug- gested). Battery voltage below 10 Recharge or replace battery.
