Please read this manual carefully for optimal inverter usage. Technical develop-
ment is sometimes quicker than manuals can be printed so we apologise for any
text, technical or illustration errors.

Introduction:

The inverters are equipped with protection against wrong usage or connection.
If any of these situations will occur, an internal buzzer can sound, red diode light
up or automatic shutdown of the inverter.

• Short circuit protection: The inverter switches off until the short circuit has

ceased.

• Low input voltage: The internal buzzer sound at low input voltage and the

red diode lights up. See ”technical data” for voltage limits. If the voltage
drops below the limit, the inverter will automatically shutdown to protect the
inverter and at same time avoid total battery discharge.

• Over voltage protection: The red diode lights up and the inverter shutdown

automatically if input voltage is too high. See ”technical data ” for voltage
limits.

• Overload protection: The red diode and lights up and the inverter shutdown

in case of constant overload or high peak loads.

• Thermal protection: The red diode lights up and inverter shutdown automati-

cally at temperatures higher than 60

C (±5

Warning:

• The inverter should be used indoor and not be exposed to rain or moisture.
• Never open the inverter yourself, repairs should be carried out by qualified

personal using original spare parts to avoid personal and property damage.

• Always disconnect the inverter from the battery before service or other

adjustment.

• Be careful and avoid sparking at the terminals when connecting the inverter

to lead acid batteries.

• Make sure to protect the inverter and the connections against children.

Remember the output voltage is as dangerous as the voltage from a regular
wall socket.

• Never use damaged mains or battery cables and make sure to only use

original replacement parts.

• Make sure to connect the inverter with correct polarity. Wrong polarity

connection can damage the inverter, which is not covered by the guarantee.

• Don’t load the inverter when connecting or disconnecting it.

Connection:

The WHS-300 and WHS-600 connects to the battery with attached cables
equipped with alligator clips. The other models, WHS-1000 and WHS-1700
connects to the battery with attached cables equipped with ring cable lugs.
1. Make sure the inverter on/off switch is in off position (0).
2. Connect red cable to positive (+) terminal on the inverter and to positive

(+) pole to the battery.

3. Connect black cable to negative (-) terminal on the inverter and to nega-

tive (-) pole to the battery.

4. The connection leads between inverter and battery should be as short as

possible, max 2m.

5. Make sure wires are tight connected to avoid sparking and voltage drops.
