PRODUCT FEATURES
All versions of the IsoBoost have the following features:
•A fully isolating hand built transformer
•A soft start system to minimise the risk of tripping the shore side breaker when first connecting.
•A sophisticated control system that will automatically select between boost and straight through mode on
US versions.
•A sophisticated control system that will automatically select between buck and straight through mode on EU
versions.
•Modbus data for optional remote monitoring the IsoBoost
Three versions are currently available
•12 kVA US - A hull isolation transformer rated for a 50A 208/240V shore cord
•24 kVA US - A hull isolation transformer rated for a 100A 208/240 shore cord
•24 kVA EU - A hull isolation transformer rated for a 100A 230 shore cord or 63 amp 400 volt cord
The IsoBoost is packaged in a robust steel enclosure, powder coated for longevity. Care should be taken to lift the unit on a
pallet or by lifting from points on the transformer frame.
The IsoBoost is designed to operate automatically with no user intervention.
On the US model the IsoBoost starts in 1:1 mode. If the output voltage is below 215 volts the unit will switch to boost mode.
If the output voltage rises above 255 volts the unit will drop back to 1:1 mode.
On the EU model the control system will start the IsoBoost in 1:1 mode if the incoming voltage is between 190 and 255 volts.
The control system will start the IsoBoost in buck mode if the incoming voltage is between 340 and 440 volts.
All versions of the IsoBoost include a sophisticated multifunction meter built into the front of the case. It provides
comprehensive monitoring of the output from the IsoBoost, including voltage, current, frequency, power and more.
All versions are fitted with a cooling fan. Air is drawn in through the front of the unit below the meter, and expelled out the
rear right hand side. Do not block any cooling vents. If the fan fails, it must be replaced.
A thermal overload switch is incorporated within the transformer windings. If the transformer overheats, this will operate
and switch off the supply. Once it cools, it will reconnect. If this ever happens, check the cooling fan and seek advice. The
unit is designed and tested to work at full load in 60°C/140°F ambient conditions.

SETUP AND CONNECTIONS
INSTALLATION
PLACEMENT
The IsoBoost should be fixed to a structural part of the ship that can accept the weight of the unit. It should be fixed down
using the clearance holes in its feet.
The product is heavy and suitable lifting equipment must be used. Do not attempt to lift the IsoBoost manually. The IsoBoost
will reject some heat. Do not block vents.
The IsoBoost transformer is not waterproof. Do not expose to rain or water.
PREPARING FOR INSTALLATION
Remove the front panel of the IsoBoost unit. You will need a 4mm hex (Allen) key to remove the fixings.
A removable gland plate is situated on the right hand side of the unit. This plate will need to be drilled to install cable glands
(not supplied).
ELECTRICAL CONNECTIONS
WARNING
The installation of the IsoBoost should be carried out by a qualified electrician. This unit case must be earthed in all modes
of operation.
AC INPUT
The unit should be wired to the shore supply receptacle with cable with a suitable rating to satisfy the relevant standards for
the vessel. If the IsoBoost is more than 3 metres or 10 ft from the inlet an inline circuit breaker may be required to meet
relevant standards:

ships monitoring system.
EARTHING
The IsoBoost must be earthed. An earthing terminal is provided for this purpose.
The typical arrangement for an isolation transformer is as follows
•All versions - Input earth or ground (from shoreline) -connects to the interwinding screen between the input and
output windings of the transformer.
•US versions- Output earth or ground is connected to the ships earth, the case of the IsoBoost, and the centre tap
of the output winding.
•EU versions- Output earth or ground is connected to the ships earth, the case of the IsoBoost, and one pole (the
Neutral) of the output winding.
Other arrangements are possible, depending on local regulations, and the design of the boat.

OPERATION
WARNING
The IsoBoost does not change the frequency of the incoming electrical supply.
If your vessel is built for 50Hz operation, do not connect it to a 60Hz supply.
If your vessel is built for 60Hz operation, do not connect it to a 50Hz supply.
Some vessels may be built to operate on either 50 or 60Hz supplies. Consult your vessel owners manual or the
manufacturer to confirm this.
12 AND 24 KVA - US
1. The shore cord of the vessel will be a 3-wire cord (2 current carrying conductors and an earth).
2. Turn off the input isolator and output breaker of the IsoBoost.
3. Plug the shore-cord into either:
4. Any two phases of a three phase 208 Volt supply –Or -
5. L1 and L2 of a US 240 Volt supply –Or -
6. L1 and N of a European 230 Volt supply (if the boat is suitable for 50Hz operation)
7. Switch on the input isolator on the IsoBoost.
8. The IsoBoost will immediately connect and soft start the transformer in 1:1 mode.
9. If the voltage is low (less than 215 volts) then, after a short delay, the IsoBoost will switch to boost mode.
10. If, during use, the voltage of the supply increases, then the IsoBoost will drop out of boost mode when the output
voltage reaches 255 volts.
11. The inbuilt display will show output volts, amps, frequency, power, energy, and more.
12. Confirm that the supply indicated on the meter is correct, and then switch on the IsoBoost output breaker.
