maintenance personal of garages that do
service on the vehicle.
Generators used on vehicles that are operated
in a hazardous environment have often to fulfill
special regulations and additional measures
have to be taken accordingly.

CONNECTING THE CABLES
1
GENERATOR OUTPUT CONNECTIONS
The generator has an output voltage between 200V and
340V. The output terminals on the and the input
terminals in the inverter has to be connected to the shielded
cable that comes with the supply. generator Includes is a kit
with installation materials, cable, numbers and glands to
guide the cable through the casing of the inverter.
Do not alter the shielded cable. Do not connect
an extension to the shielded cable.
Different cable lengths are available from your Whisper
Power dealer.
Each cable conductor of the shielded cable is marked with
a number 1 up to 5. Connect each cable wire to the terminal
with a corresponding number.
1, 2 and 3 are AC1, AC2 and AC 3.
4 and 5 are the auxiliary field wires that control the output.
On the generator the wires has to be fastened with screws
M3x1.5. Do not fasten too tight; apply a torque wrench and
apply a maximum torque: 0.3 -0.5 Nm.
The cable has to be connected to the inverter with the
connecter in the delivery accordingly to picture 8 below.

POWER SUPPLY
The inverter needs 12V from the battery to control the
electronic system. A two wire 2.5mm2 cable (not included
in the delivery) is used to connect the inverters to the
“contact key” of the drive engine. A fuse of 3 amp should be
applied to protect the circuit and an additional on/off switch
could be applied. The 2 pole connector in the delivery must
be used according to figure 9.

INVERTER OUTPUT CONNECTIONS
Figure 10 shows where to connect the AC output
connection cable. All electrical connections, cable types
and sizes must comply with the appropriate national
regulations.
Yellow/green – earth/grounding.
Next is -0- (neutral) and on the right L1 (line).
For the power cable we recommend the use of 3 wire single
phase oil resistant cable with a sufficient cross sectional
area. One wire for earth is included. For long cables it is
recommended to apply cables with a larger cross section
(refer to ISO 13297 annex A).
