DANGER

The instructions given in sections 2.2  2.3  2.4 are

addressed to qualified technicians only.

2.2 MOUNTING THE GENERATOR

Generators mod. 2500  4000 are provided

with fixing brackets,vibration dampers and petrol filter to be

placed on the fuel feed hose to the generator. Brackets

allow either suspended type "A” mounting (see fig. 3) or

traditional type "B” mounting (see fig. 4).

This is made possible by the supporting frame of the outer

casing.

Generator mod. 5500 is provided with brackets for fixing

the external seal, brackets for anchoring the unit, vibration

dampers, silencer (pos. 29 fig. 16) to be coupled to the

exhaust hose delivered as accessory AG 125 (pos. 34 fig.

16), and fuel filter which is standard installed inside the

casing (pos. 33 fig. 15). The brackets (pos. 31 fig. 16) which

allow to fix the seal (pos. 35 fig. 16) allow to mount the

generator complete with seal inside the arranged

compartment and to perfectly seal the vehicle side. The

exhaust hose can be positioned at will as shown in fig. 16

by rotating the curve inwards to either upper position or

lower position. By removing the curve, it is also possible to

directly fit the exhaust pipe by crossing the casing on its left

hand side. The prearranged floor must tolerate both the

generator mass and the vibrations due to the motion of the

vehicle ("TYPE B” mounting).

The type “A” mounting (suspended installation) offers the

following advantages: reduced overall dimensions, quick

installation, easy access for both ordinary and extraordinary

maintenance operations.

Make sure there is enough space around the generator

casing for air to pass freely (for cooling). It is also necessary

to leave at least 20 mm distance between the casing and the

surrounding parts.

If the breathing manifold is positioned behind one of the

vehicle's wheels, make sure that the tyre is prevented from

throwing

water into the casing when travelling on wet roads.

For the type “A” mounting, use the plate supports provided

to ensure that the genset is fixed securely. If type “B”

mounting is preferred (traditional installation), a watertight

compartment (fig. 2), set towards the vehicle interior and

having the dimensions given in section 1.3.3, needs to be

prearranged, with exhaust holes and air inlets drilled into the

floor and door. In addition, use an exhaust union (fig. 4),

supplied as accessory, to be fixed directly onto the generator

casing with screws or rivets. In order to prevent the exhaust

gas recycling within the compartment, place flameproof

sealing around the exhaust union.

2.3 ELECTRICAL CONNECTIONS

For the 230V use a standard cable with crosssection

according to table 1 below. Pass it inside the casing via the

airlead (pos. 30 fig. 7 and 9) and connect to the terminals

(pos. 17/18 fig. 6 and 14). Connect the earth wire to pos. 15.

The electrical circuit should have a relay or changeover

switch (such as accessory AG102/AG113), so as to prevent

any damage to the generator when the camper is connected

to an external mains supply (precedence is automatically

given to the mains).

2.3.1 CONNECTION OF BATTERY

RECHARGER

Use a wire with minimum crosssection according to table

1 above to connect the terminal (pos. 16 fig. 6 and 14) to

the positive lead of the battery to be recharged.

Insert the AG111 voltage regulator, or alternatively a switch,

to interrupt recharging when complete.

(See wiring diagrams, pages 55 ÷ 71).

2.3.2 CONNECTION OF STARTER BATTERY

For starting the generator, connect the positive terminal of

the vehicle's starter battery to pos. 12 fig. 6 and 14 using a

flameresistant sheathed cable having a crosssection

according to table 1 above.

The earth cable should have the same crosssection and be

connected from pos. 13 to the vehicle chassis. Make sure

that a clean, rustfree contact is made (i.e. rub down surface

if painted), and protect with grease.

2.3.3 CONNECTION OF REMOTE CONTROL

PANEL

Fix the control panel in desired position inside the vehicle

and use the individuallytested AG103 extension cable to

connect it to the genset by means of the connector pos. 14

fig. 6 and 14.

2.4 INSTALLING THE FUEL TANK

Install the fuel tank as near as possible to the generator and

if possible on the same horizontal level, or up to 30cm

below. As well as reducing the length of fuel pipe as much

as possible, make sure it is not bent or squashed. Do not

put the tank near sources of heat, and make sure that water
