ENGLISH QUICK INSTALLATION INSTRUCTIONS

7

Check all wiring. If all wiring is
OK:

 Place the inverter fuse.
 Switch on the Inverter.

6

Connect the AC load to the AC socket.

For safe installation,
 The chassis ground terminal (see Figure 1,

reference 7) must be connected to the central
grounding point of the vehicle/ ship

 The neutral conductor (N) of the AC output of

the Inverter must be connected to the safety
ground (PE/GND) and a ground fault circuit­interrupter (GFCI) must be integrated in the
wiring of the AC output

Refer to section NEUTRAL GROUNDING of this

Disconnect the electrical power:

 Switch off all consumers,
 Switch off all charging

systems.

 Remove the battery fuse.
 Check with a suitable

voltmeter whether the DC
installation is voltage free.

overview of a basic stand alone
installation of the Inverter

However; please review the entire manual for
connection of additional features and to ensure
best performance and years of trouble-free
operation.

Use isolated tools!

USER’S MANUAL 700, 1000, 1500 WATT INVERTER ENGLISH

PRODUCT DESCRIPTION AND APPLICATION

The Marinco inverters convert a DC voltage to a pure AC
sine wave voltage.

SAFETY INSTRUCTIONS

WARNING!

Before using the Inverter, read and save the
safety instructions

 Use the Inverter following the instructions and

specifications stated in this manual.

 Connections and safety features must be executed

according to the locally applicable regulations

 Operation of the Inverter without proper grounding

may lead to hazardous situations!

 Use DC-cables with an appropriate size. Integrate a

fuse in the positive wiring and place it nearby the
battery. Refer to the specifications.

 If the positive and negative wires on the DC-input

(battery) are exchanged, the Inverter will be damaged.
Damage of this kind is not covered by guarantee.
Check whether all connections are connected
correctly before placing the fuse.

 Do not connect the AC-output of the inverter to an

incoming AC source.

 Never connect the Inverter in parallel with any other

inverter.

 Never open the housing as high voltages may be

present inside!

UNPACKING

The delivery consists of the following parts:

 The inverter
 This user’s manual
 Four ring terminals

After unpacking, check the Inverter for possible damage.
Do not use the Inverter if it is damaged. If in doubt,
contact your supplier.

NEUTRAL GROUNDING

For safe installation,
 The chassis ground terminal (see Figure 2, ref. 7)

must be connected to the central grounding point of
the vehicle/ ship

 The neutral conductor (N) of the AC output of the

Inverter must be connected to the safety ground
(PE/GND) and a ground fault circuit-interrupter (GFCI)
must be integrated in the wiring of the AC output. See
below for model specific information.

Refer to locally applicable regulations on these issues!

120V models

With the 120V models the neutral conductor of the AC
output circuit of the Inverter is internally connected to the
safety ground during inverter operation automatically and
a ground fault circuit-interrupter (GFCI) is already
integrated in the AC output circuit of the Inverter.

230V models

With the 230V models there is no connection made inside
the inverter between either the line or neutral conductor
to the safety ground.

DIP SWITCH SETTINGS

See Figure 1, ref. 6. Under normal circumstances there is
no need to change the default settings of the DIP
switches: the inverter is immediately ready for use.
To save energy from the battery in no load operation, DIP
switches S1, S2 and S3 can be used to adjust the Power
Saving Mode. The Power Saving Mode scans the output
and when it detects a load which is higher than the
selected threshold value, the inverter is switched on
automatically.

INSTALLATION
Choosing a location to install

 Install the Inverter in a well-ventilated room protected

against rain, snow, spray, vapour, bilge, moisture and
dust.

 Ambient temperature: –25 ... 40°C / –13…104°F;
 Never use the Inverter at a location where there is

danger of gas or dust explosions

 Mount the Inverter in such a way that obstruction of

the airflow through the ventilation openings is
prevented. No objects must be located within a
distance of 10 cm / 4 inch around the Inverter.

 Do not install the Inverter in the same compartment as

the batteries. Do not mount the Inverter straight above
the batteries because of possible corrosive sulphur
fumes.

Before you start

 Be sure that the output of the supplying source

(battery) is switched off during installation. Also be
sure that no consumers are connected to the battery
during installation, to prevent hazardous situations.

 Before installing the Inverter make sure the main

switch (Figure 1, ref. 1) is set to the OFF position.

 Check that the battery voltage is the same as the

input voltage of the Inverter (e.g. 24V battery for a

24V input voltage). Also check that the output voltage
satisfies loading requirements

 A DC fuse holder must be integrated in the positive

wiring. The DC fuse should be placed last of all.

 Use four Ø4.5mm (No. 8) screws to mount the

Inverter to a solid surface. See Figure 3.

Wiring

 Connect DC wiring as shown in Figure 2: the black

terminal (9) NEG (–) to the negative (–) pole of the
power source / battery, the red terminal (8) POS (+) to
the positive (+) pole of the power source/ battery.
Integrate a DC fuse holder in the positive wiring, but
do not place the fuse yet. Assemble the DC wiring
exactly as indicated. Do not place anything between
the ring terminal and the terminal surface. Make sure
that all DC connections are tight. Recommended
torque: 11.7-13 Nm / 104-115 InLbs

 Chassis ground: Use a cable AWG8 / 6 mm² to

connect the CHASSIS GROUND terminal (7) to the
central ground.

 Remote operation switch (option). If you want to

operate the Inverter on a remote location, you can
install a switch as indicated in Figure 2. When the
contact is closed, the Inverter is switched on.
