4. Remove the knobs of the 12V terminals (5) and attach the free ends of the DC leads.
Connect the black DC cable to the Negative Connector (-) and the red DC cable to
the Positive Connector (+). Tighten the knobs. Double check that the cables are
connected to the correct connectors. Connect the free end of the positive red DC
cable to the battery positive (+) terminal. Connect the free end of the negative black
DC cable to the battery negative terminal (-).
• Make sure the DC cables cannot come into contact with each other and short the
battery terminals
• Polarity must be correct as the inverter’s external DC fuse will be blown by incorrect
polarity
Operation
Connecting a load
1. Before connecting any appliance to the inverter, toggle the On/Off Switch (4) to the
on position. The green Power Indicator Light (1) will illuminate. The inverter is now
ready to be used
WARNING:
DO NOT connect loads greater than the rated maximum continuous power
output of the inverter (see ‘Specification’).
Notes:
• Some devices do not operate well with an inverter supplying moderated sine
wave current. Those devices will only operate properly when connected to a
standard household power socket, which provides current with pure sine wave. It is
recommended that such devices are only operated from household power sockets
• Some appliances (televisions, stereos, motors, neon lights etc.) may require a much
higher starting power than their rated power. If the appliance will not start, the
maximum output of the inverter has been exceeded. Reduce the total load on the
inverter
• If the appliance to be connected does not have its wattage (W) indicated on it (e.g. on
the rating plate), the wattage can be calculated by multiplying the amperage (A) by 230
2. Electrical appliances can now be connected to the 230V Outlet Socket (3)
Low battery protection
Note:
In order to prevent your vehicle battery from being discharged completely, this
inverter is equipped with a low voltage alarm and automatic low battery shutdown.
• DO NOT connect loads greater than the rated maximum continuous power output of the
inverter (see ‘Specification’)
Problem
Possible cause
Solution
Inverter will not operate
Low battery voltage
Charge or replace battery
An incompatible AC device is connected
Disconnect AC device
Inverter in thermal shutdown
Allow inverter to cool before switching on
DC cables are poorly connected
Check DC leads for damage and secure connections
Fuse ‘blown’
Replace fuse (see ‘Maintenance’). Contact your authorised Silverline service centre if
fuse blows repeatedly.
Electrical appliance will not operate
Incompatible AC device is connected
Disconnect AC device
Current or starting current requirements of AC device are
too high
AC device not compatible
Inductive load AC device not compatible with modified sine
wave AC
Try connecting a low-power resistive load device, like a small filament lamp, at the
same time. This may cause the inductive load device to function
Low voltage alarm on continuously
Poor electrical connections
Check/clean electrical connections
Inadequate power supply
Check 12V system capacity
Low output voltage
Inverter is overloaded
Reduce load
Input voltage is below 11V
Charge or replace battery
Television/stereo interference
Inverter is located too close to aerial
Move inverter/aerial
Aerial cable is not shielded
Use shielded cable
Troubleshooting
• If the supply voltage drops to 10.5V, the low battery alarm will sound and the Low
Battery Indicator Light (2) will illuminate. This indicates that the battery should be
charged. If the supply voltage is allowed to drop to 10V, the inverter will automatically
cut out. To restart the inverter, switch off, charge the battery, and switch back on
• A typical 12V battery will have an operating time of at least 1-2 hours. It is
recommended that the vehicle’s engine is started and run once every hour to ‘top up’
the battery
Note:
The inverter may shut down as the engine is started due to the high electrical load
generated by the vehicle starter motor.
Overload protection
• This inverter is equipped with built-in thermal protection. If an overload causes the
internal parts of the inverter to overheat, it will automatically shut down
• To restart, switch off, reduce the load, allow the inverter to cool, and switch back on
Maintenance
WARNING:
ALWAYS disconnect the device from the power supply before cleaning or
carrying out maintenance.
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly,
and shorten the device’s service life. Clean the body of your machine with a soft brush,
or dry cloth. If available, use clean, dry, compressed air to blow through the ventilation
holes (where applicable)
Replacing fuses
• A blade type fuse is fitted into the rear of this device
• When blown, only replace with another fuse of the same type and rating (see
‘Specification’)
• Determine the source of the overload or short, and remove before switching power back
on. If the fuse keeps blowing it indicates a fault condition with the unit
Disposal
Always adhere to national regulations when disposing of power tools that are no longer
functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic equipment
(WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way to
dispose of power tools
