INTRODUCTION
1. The purpose of this HR 34.2 Systems Manual is to explain the location, function and
operation of the key systems and equipment on board RAFSA(O) HR 34.2 yachts. It
supplements the Hallberg Rassy Instruction Book – All Models 2016/2017, which is carried
on board. This Manual supplements RAFSA(O)’s Safety Management Policy and our
SOPs; it forms a critical component of the RAFSA(O) Document Set.
2. Both documents also form part of the vital handover information to the skipper and
crew and should be used as a routine reference source. It is not designed to be
exhaustive, rather it covers the key equipment on board that is not better covered by the
manufacturer’s manual e.g. the Raymarine Navigation suite. Further information is
available from the yacht Oi/c or other RAFSA committee members, whose contact details
are in the Boat Folder.
2. Suggested amendments should be forwarded to the Training Principal at

CHAPTER 1 - BATTERIES AND BATTERY SWITCHES
1. The HR yachts are equipped with separate domestic and start batteries located under
the lateral saloon seat amidships, forward of the saloon table. Both can be isolated by the
Battery Isolation Switches accessed from wooden door, under the inboard end of the lateral
saloon seat at the base of the mast post.

2. Charging. Don't underestimate the time required to charge the batteries. Full
charge may take up to 15 hrs using the engine, dependant on electrical load, or overnight if
the yacht is plugged into shore power (charging is automatic. DO NOT adjust the charger
settings – irreparable damage can occur). The alternator on the main engine will give full
charge at 1300 rpm. The only volt metre is on the Furuno cockpit display; you will need to
find the correct page. As a minimum, this should be checked daily before sailing, once
shore power has been disconnected, ideally it should be checked and hourly when
completing the ship’s log. The voltage should not be allowed to exceed 14.2V and should
not be allowed to fall below 11.5V. If this occurs; charge the batteries as soon as possible.

CHAPTER 2 - 240V ELECTRICAL SYSTEM AND IMMERSION HEATER SWITCH
1. Safety with 240 V on board. The 230V system is fitted with an earth leak switch
(residual current circuit breaker) and a number of combined switches and overload circuit
breakers for the different outlets. The Ground Fault Circuit Interrupter (GFCI) switch is a
safety device for preventing electric shock accidents if an electric lead should be touched; if
it is triggered off, all outlets will be isolated. The GFCI is located on the electrical consumer
unit, which is located inside the starboard cockpit locker, outboard. Try to re-engage by
lifting the toggle switch after first breaking each of the circuit breakers.

2. Danger! To minimise the risk of shock or fire:
• Connect the shore connection cable on board first before connecting it to the
shore outlet.
• Disconnect the shore cable at the shore outlet first before disconnecting on
board. Replace the rubber cap over the yacht’s mains electric socket carefully.
• Use correct adapters to fit different shore outlets.

3. Remember: if there is no earth breaker ashore, the cable faults are not protected
against electrical shock between the boat and the shore.
4. Note: The GFCI switch is so sensitive that rain or a damp connection can trigger it.
Do not work on energized AC systems.

CHAPTER 3 - ELECTRICAL SERVICES CONTROLS
12V
1. The battery isolation switches (engine start and domestic) are behind a wooden door,
at the mast foot, in the forward saloon. The emergency engine start (connects the domestic
battery to engine start circuit) is located on the aft side of the quarter berth hanging locker.

2. With the battery isolation switches selected on, the 12V electrical services are
controlled from the electrical services control panel outboard of the chart table. Switches
and circuit breakers (push buttons with built in safety trip) are labeled and self-explanatory.
The panel also houses:
• Fuel tank gauge
• Fresh water tank gauge
• Shore power light (illuminated when 230V connected)
• 12V lighter socket (there is also one in the quarter cabin)
