Power Bright APS300 User Manual

Read these instructions before connecting and using your
PowerBright™ Pure Sine Power Inverters. Failure in observing
this warning may result in injury to persons and damage to
equipment.

General safety and installation information.

Warning! The following fundamental safety measures must be

observed when using electrical equipment to avoid danger of:

- Electric shock

- Fire

- Injury

About the unit itself

- The inverter must only be used for the purpose specified by
the manufacturer.

- Do not operate the inverter if the housing of cables are
damaged.

- The inverter must be positioned and secured safely in order to
avoid knocking over or dropping

- If casing needs to be opened, make sure Input cables have
been properly disconnected.

- The inverter must be kept in a safe place out of the reach of
children.

- The inverter may not be operated in a damp or wet
environment.

- The inverter may not be used in rooms containing flammable
materials.

- Make sure the inverter is well ventilated.

- Service and repair may only be carried out by skilled persons
who are familiar with the risks involved and the relevant
regulations.

Caution by installation on boats!

- Incorrect installation of electrical units on a boat may lead to
corrosion of the boat. Therefore, please let a (boat) electrician
carry out the installation of the inverter.

Intended use

The inverter is suitable for e.g. high-quality appliances from the
audio, video or PC.
The output voltage corresponds to the standard one of your
socket (pure sinus-voltage).

Attention! Please note that appliances like drills, TV’s or
refrigerators require a high starting-current which is far over
the nominal current.

With its low weight and the compact design the inverter can be
easily installed into campers, commercial vehicles or motor and
sailing yachts.

Note: Some devices contain AC motors or compressors (IE:
drills, refrigerators, etc.) which require a higher wattage
during startup. This wattage typically exceeds the rating
listed on the device.

Required tools and installations equipment
Depending on type of installation, the following tools are
required:

-set of screw drivers

-drill and set of bits

-wrench

-crimping shears for the12/24V wire connection
For connection of inverter to the battery, the following cable
connecting hardware is needed:

-2 different flexible cable connections.

-Various terminals, multi-core cable ends

Caution:
Before drilling any mounting holes, make sure that there are no
wires, fuel lines or tanks directly below the surface being
drilled.

Installation
The inverter has to be installed in a dry and clean place not
being exposed to humidity.
Make sure there is proper ventilation.
Keep at least a free space of 10 cm surrounding the inverter.
If installed into housing, make sure there’s good ventilation.
The air intake on the bottom of the inverter and the air outlet on
the back side may not be blocked.
In case of ambient temperatures of more than 35C (e.g. engine
or heating room, direct sunlight), the inverter will switch off
automatically, because of self heating effects during operation.
The installation surface must be balanced and sufficiently
strong.

Installation of the inverter

-Adjust the inverter to the chosen installation place and mark
the fixing points.

-Fix the inverter by using the self chosen fixing method.

Electrical connection
General instructions for electrical connection.
In case of the inverter is installed into vehicles or boats it has to
be connected to the chassis (ground).
If cables have to be inserted to metal walls or other sharp­edged means, use a cable duct or cable bushes.
Do not pull the cables.
Do not lay cables loose or in sharp bends on electrical
conducting materials (metal).
Do not lay 110V mains cable and 12/24 VDC cable together
into the same cable duct.
The specified minimum cable cross section must be complied
with.
Secure cables properly.
Lay cables in such a way that no tripping is possible.
Lay cables in such a way that no exposure to or risk of damage
is possible.

Cables: Make sure to

Connection to the battery

-Lay the flexible connecting cable (positive) and (negative) from
the battery to the connecting terminals of the inverter (take
cable cross section from the table).

-Connect first the positive, then the negative cable.
! Make sure the terminals are not reversed!

Reverse polarity connection will blow the internal fuses. This
will void the warranty.

-Lay the flexible chassis ground cable from the chassis of the
vehicle to the chassis ground on the rack of the inverter.

-Connect the chassis ground.
! Reverse polarity connection of the battery wires can damage
the inverter. Do not use the inverter with electrical systems
using positive ground.

Operation: 300 Watt Pure Sine Wave Inverter
Power on

On the LED control “Power” lighting - Green LED.
Over load
One the LED control “Over-Load” lighting-Red LED.
Over temperature

On the LED control “Over-Temp” lighting-Red LED.

Problem Possible Cause

No output voltage,

No output voltage, OVER-TEMP
LED Lights Red

Overload LED Current consumption of the device is

1. On/Off switch is not in the power ON
position.

2. Bad contact of the connections
between battery and inverter.

3. Internal fuses blown. In this case,
send the unit back to Power Bright for
repair.

The inverter has been overheated.
Switch off the inverter and the device.
Wait approx. 2 minutes and switch on
the inverter only. Reduce the load and
make sure that there is better
ventilation for the inverter. Then switch
on the inverter and the device again.

too high. Also there could be a short of
the device. Switch off the inverter and
disconnect the device. Switch on the
inverter again. If the OVERLOAD LED
is off, there is a short circuit in the
device or the total load was higher
than the specified wattage of the
inverter. Check the connecting cable of
the consumer for mechanical
damages.

Audible signal in case of under
voltage

Battery voltage too low. In case of the
battery load voltage falls below 11V
resp. 22V. The battery has to be re­charged.
