SUNRAY UPS Combined inverter & Charger
Basic wiring for the Power Star W7 Series
Warning:    High voltage, do not open unless qualified to do so;
Please read instructions before working on this product.
When the PS W7 is in the inverter mode , the ‘ through the box’ earth line is automatically disconnected from the input earth and joined to the output neutral, complying with the natural earth inverter requirements if you what to maintain a trough earth simply connect the input earth to the output earth.
WHAT CABLE TO USE in mm2:
A charger or inverter
Cable run distance
0-1.54m
Cable run distance
1.5-4.0m
125-180 A
50 mm2
70 mm2
180-330 A
70 mm2
90 mm2
Please note that if there is a problem obtaining, for example 90 mm2 cable, use 2*50 mm2, or 3*35 mm2. To adopt one cable is always the best, cable is simply copper and all require ins the copper, so it does not matter if it is one cable for ten cables as long as the square areas adds up.
Performance of any products can be improved by thicker cable and shorter runs, so if just keep the length as short as possible.
Check list
1)Ensure that the inverter has the correct DC voltage for your boat or vehicle system. ie 12v or 24v/48v.
2)Fit as close to the batteries as possible, the shorter the DC cables the better. Voltage drofloat up
p 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 230V 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.
Ensure the fitting instructions are fully understood before fitting this product.
Installation
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 90 mm2 cable then use 3 *35 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 100-500 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 30Am Ps, so fuse at 40A (allowing also for charger consumption) if you intend to use the full through power for standard 13-16 amps throughput then a 20A fuse would be appropriate.
