4.2 .- INSTALLATION OF PORTABLE UNITS
4.2.1.- Placement
T
his type of unit must be installed in well ventilated areas in order to ensure sufficient flow of coolant air and
preventing combustion smoke from sitting in the engine’s exhaust.
The unit must be placed in a location that can safely bear the full weight of the generator unit and guarantee its
stability both horizontally and vertically.
It should always remain at a distance that allows access to the interior of the electrical generator (at least 1 meter
away from any building or wall).
Avoid installing in areas with moisture or locations where water could get into the interior of the unit.
* Note: Exhaust can be supplied with optional spark arrester in the exhaust tube for Ex zones.
4.2.2.- Fuel
A
s diesel fuel is used, keep in mind the safety instructions previously mentioned in point 2 - BASIC SAFETY
RULES.
Before operating, check the fuel level to ensure that the tank has the amount needed by the generator unit for an
entire work day.
There is a optional of quick conectors for external fuel tank. We can connect them with conductors through canopy
fuel point for replenishing the generator base tank.
You should consider this series of points:
1) In order to connect or disconnect, you should move backwards the female lock fitting.
2) Make sure that the external tank aspiration circuit does not contain air.
3)
In the external tank, the aspiration connector should be male and the return connector female, both are 3/8
BSP connectors.
4) Return should be correctly connected.
5) Connectors have to be watertight; they lock when they are disconnected.
6)
T
he distance between tank and genset has to be as shorter as possible. If you observe engine anomalous
behaviour (lack of power for aspiration problems), you should have to reduce distance or increase the hose diameter.
4.2.3.- Prior to starting generator
Before starting up the generator, inspect the consumer power supply conductors to make sure they are in perfect
condition and that the consumers are disconnected; the unit should always be started up at no load.
Make sure that there is nothing obstructing the ventilation ducts and that there are no foreign objects inside the unit.
Make sure the fluid levels of the electrical generator are adequate for the service the unit will be providing and that
there are no leaks or spillage.
4.2.4.- Electrical connection
The connecting of cables that supply consumers must be performed by qualified personnel; these conductors should
be connected to terminals U V W and N or L1 L2 L3 and N or to the socket panels
.
T
he four-pole circuit breakers have copper bus bars to facilitate the connection with conductors and prevent
deterioration produced by repeated connecting.
Depending on the options selected, sockets may or may not have individual protection, which is distinguished from
the general unit protection by the use of an individual circuit breaker for each socket.
Portable units are defined as those moved to different work sites at least twice yearly.
