Basic wiring for the Power Star W7 Series
 

1. Ensure that the inverter has the correct DC voltage for your boat or vehicle system. ie *2v or *4v/*8v.
2. Fit as close to the batteries as possible, the shorter the DC cables the better. Voltage drop on long cables will effect the unit’s performance.
3. Do not reverse the cables! Connect the red cable to the positive terminal and the black cable to the negative terminal of the battery. In the event of reverse polarity the unit could be totally destroyed.
4. Always use the inverter in an environment which is well ventilated, not exposed to direct sunlight or a heat source, away from water, moisture, oil or grease, away from any highly inflammable substance, out of reach from children.
5. The output voltage of this unit must never be on your AC system at the same time as any other AC source such as the **0V external mains line or a generator. All external power must go through the PSW7.
6. Always switch on the PSW7 first, before plugging in any appliance.
7. Under new electrical legation only professional electrocutions should install the product.

1. Position the unit as close to the main battery bank as possible
2. Position in a cool, dry & well ventilated space.
3. Orientation of the unit is not critical.
4. Either purchase the standard cable set from Dealer which is about 1.5 meters, or if using your own cable, use the cable size chart provided on the installation drawing to ensure you have thick enough cable for the DC leads. In the event of not being able to get the size requested (it cab be hard to get thick cable) then simply add multiple length of thinner cable, i.e. if you cannot get*0mm2cable then use 3 **5 mm2  cable, ate the end of the day its just copper we need.
5. Fit a fuse suitable for the job, again look at the installation drawing. We have a full range of hihg current fuses in the GANLR range of gold fuse products, ranging form ******0 Am Ps.on the DC side
6. Connect the cables from the batteries to the fuse then to the unit, this way if there is a fault at the unit the fuse is already in place and this will be safe. In the event of a isolation switch being used, please ensure the rating of the switch can handle the power of the unit.
7. Ensure the the unit is switched off during installation.
8. On the AC side ensure the shore power (all external AC sources) are totally disconnected, connect the output from the inverter to suitable Residual Current Breaker (R.C.D for the earth protection) and current over load trips Fuse the AC input side depending on through power requirements, the max through power is *0Am Ps, so fuse at *0A (allowing also for charger consumption) if you intend to use the full through power for standard ****6 amps throughput then a *0A fuse would be appropriate.
9. We recommend Multi core tri rated AC cable, if used on a boat or vehicle, as this is much safter where vibration is likely. Only use single solid household AC cable if the product is being used as a power source for a house or platform free of vibration.
10. Before attempting to switch on the unit, please ensure you have selected the correct battery type on the small battery type selector switch on the front of the mian box, rotate the switch to your battery types. The progressive charge control software will automatically adjusted for battery bank size and state

• Boost CC Stage: If AC input is applied, the charger will run at full current in CC mode until the charger reaches the boost voltage.
• Software timer will measure the time from AC start until the battery charger reaches 0.3V below the boost voltage, then take this time as T0  and T0  * *0= T1.  
• Boost CV Stage: Start a T1.  timer; the charger will keep the boost voltage in Boost CV mode until the T1.  timer has run out. Thn drop the voltage down to the float voltage. The timer has minimum time of 1 hour and a maximum time of *2 hours.
• Float Stage: In float mode, the voltage will stay at the float voltage.
• If the AC is reconnected or the battery voltage drops below *2Vdc/*4Vdc, the charger will reset the cycle above.
• If the charge maintains the float state for *0days, the charger will reset the cycle.

1. Ensure the battery bank is totally isolated from anything else on the boat or vehicle; the high voltage applied by this setting could destroy all your electronics and other electrical equipment still connnected (hence all these instructions are in red, this is a very dangerous mistake.)
2. Make sure the battery compartment is very well ventilated and battery caps are removed.
3. Switch the battery type selector to the correct position, then switch the AC power on.
4. Because this is such a dangerous setting there is a 4 hr time out period build into the software, however on a very large battery bank this may not be enough and the unit may need to be switched off and on again to do another cycle.
5. What to expect on this cycle.

1. After the unit is installed, using the panel on the front of the unit, and with the shore power (**0/**0VAC) still disconnected, switch the unit on. The leds will cycle through the test routine, then the unit should go into inverter mode and **0/**0V should be produced on the output AC terminals(provided the batteries are over *1 volts).
2. If the above is ok, then connect the shore power to feed **0/**0V into the PSW7, after a short while, the inverter should go off line, and feed the shore power through the inveter. Changeover is about *0 millisecs (so fast that you should not be able to notice it) and the battery charger should come on-line and go through it’s charge sequence ending, after ***0hrs, with float voltage.
