1. General InstructIon
Thank you for choosing our product. This manual contains
important safety and operation instructions. Please read
this manual before use. The WP-GI NeeDS To Be INSTALLeD
By A SKILLeD TeChNICIAN.
1.1 safety instruction
As dangerous voltages and high temperatures exist within the
WP-GI, only qualified and authorized maintenance personnel are
permitted to open and repair it.
This manual contains information concerning the installation and
operation of the WP-GI. All relevant parts of the manual should
be read prior to commencing the installation. Please follow the
local regulations. Any operation against the safety requirement or
against design, manufacture and safety standard are out of the
manufacturer warranty.
1.2 General precautions
- Do not expose the WP-GI to dust, rain, snow, liquids or
gases of any type, it is designed for indoor use only in a
well ventilated area.
- Do NoT block ventilation, otherwise the WP-GI may overheat.
- To avoid fire and electric shock,make sure all cables have the
correct thickness and are connected well.
- Please do not put any inflammable goods near to WP-GI.
- Never place the unit directly above batteries; gases from
a battery will corrode and damage the WP-GI.
2. General DescrIptIon
The WP-GI is a high efficiency galvanic isolation transformer with
softstart function integrated. The softstart prevents tripping of
circuit breakers when the transformer is magnetized at startup.
It can be used as 230V to 230V transformer, 110V to 110V, 110V
to 220V and 230V to 115V. In every situation, the full power can
be taken from the output. The softstart adapts according to the
chosen input voltage.
The frequency of the AC output voltage
will be the same as the frequency of the input voltage.
For protection, a residual current detector (ground fault circuit
interrupter) with integrated circuit breaker should be installed up
stream. An optional cover plate can be installed which can accom-
modate a standard DIN mounted device (see installation section).
2.1 safety device
The AC output (secondary) connection is electrically isolated from
the AC input (primary) connection and floating with respect to
earth potential.
Note that the Neutral on secondary side can be connected to the
Pe on secondary side which polarizes the signal AC out. Never
touch the connections within when the unit is live.
2.2 corrosion prevention for boats and ships
The device is mainly designed to be used as a galvanic isolation
transformer to break the ground loop which causes galvanic corro-
sion on metal hulls on boats and ships.
The primary protective earth (Pe) connection is terminated in the
isolation transformer without making any electrical connection.
The Pe of the secondary side is connected to a shield inside the
transformed and the metal cabinet of the WP-GI. This secondary
Pe connection is connected to the grounding system of the ship
forming a safe situation on board without the grounding loop to
shore which causes the galvanic corrosion.
A special connection can be made when the boat is on dry dock,
connecting the primary Pe to the secondary Pe temporarily.
2.3 protections
The equipment is being protected against basic failures through
hardware protection circuitry making it a robust and reliable
equipment.
overheat protection
In case a too high transformer temperature is detected, the WP-GI
will switch off the output and the ´PRoTeCT´ led inside the connec-
tion compartment will be lit.
WARNING:
After cooling down, the WP-GI will
automatically reconnect the AC output.
High voltage protection
In case 230V is applied while the 110V setting is selected, fuses
F1 will be blown which disables the softstart function. The unit will
not switch on.
WARNING:
Fuses F1 are inside the unit.
Replacement of the fuses must be done by a
skilled technician only.
If the correct voltage is selected and connected when the fuses
F1 are blown, the transformer will magnetize immediately. Usually
this will result in tripping of the circuit breaker installed at the grid
input side upstream. The fuses F1 should be replaced.
2.4 Before installation
Before installation choose:
- input voltage
- output voltage
- connect secondary Pe to secondary N according to regulations.

before installing the cables or opening the cover.
Material list
The unit is packed with following materials. Please confirm the
series number on the unit is the same as on the outer carton
- WP-GI
- User manual

- Cable jumper to connect primary Pe to secondary Pe
location
Please install the WP-GI in a dry, clean and good ventilated location.
Working temperature: -10 to 70º (derating above 45º)
Storage temperature: -40 to 70º
Relative humidity:
0 to 95%, non-condensing
Cooling:
Forced air, temperature controlled.
General advice
Before connecting the equipment, verify the AC input voltage and
required output voltage according to the installation.
WARNING:
Do not connect the output of this
equipment to your AC system in parallel with any
other AC source
It is recommended to connect a Ground Fault Circuit Interrupter or
Residual Current Circuit Breaker and Circuit Breaker (20A or 40A)
at the AC input side (upstream). on the AC output side, a circuit
breaker is recommended before each branch.
It is not necessary to install a circuit breaker directly at the output
of the WP-GI when appropriate cables have been used at input
and output side.
WARNING:
Recommendations in this
manual are just an advice. Always follow local
regulations! The installer is responsible for
correct installation of the device!
Installation and connection
WARNING:
For the safety of the installer,
cut off all power before installation
Mount the Wp-GI
The WP-GI must be mounted vertically. Keep the vibration as small
as possible. Keep proper ventilation space around the unit: 200mm
to the wall, floor and other equipment.
The WP-GI can be mounted by a suitable central bolt or stud and
bolts or studs at the bottom. See drill pattern:
only mount on a solid (concrete or metal) wall.
The unit weights 25 kg. Schematic overview:

Wiring recommendation
Please find the following minimum wire size.
connecting the ac cable
AC input cable:
Pull the AC input cable through the gland and connect it to the
AC input connector. Connections are marked as “L”-line,
“N”-neutral (or “L2”-line) and “Pe”-earth. Make sure it is tightly
screwed. Choose the proper input terminals according to the table
found on the connector PCB inside the connection compartment.
choosing the input voltage:
The input and output voltage can be selected independent from
each other. It is done in the following section in the connection
compartment.
Note that if dual phase 110V is connected to the input,
the Neutral is not connected.
