engineer is covered, but is limited to a reasonable number 
of hours and reasonable rates in relation to the actual 
repair work that has to be done.  
Travel expenses and travel hours are not covered. Also 
not covered is the labour required to take a generator out 
of a vehicle or for reinstallation. There is no cover for 
labour needed to get access to the generator, for example 
to remove equipment or parts of the vehicle body etc.  
 
Goods to be delivered under warrantee will be invoiced. 
Only after the faulty goods are returned will the invoice be 
credited. Payment in advance may be required or 
guaranteed by credit card. If after the faulty goods are 
returned, it is indicated that the failure was not covered by 
warranty a credit will not be issued. For example if a 
Printed Circuit Board is returned with clear damage 
caused by water, warranty will be refused.  
Freight costs to deliver spares by normal mail or carriers is 
covered under warranty. Special services like express 
mail, overnight delivery etc. are not covered. Taxes and  
duties are not covered. For shipments to remote off shore 
areas any additional costs incurred over normal carriage 
will be invoiced to the customer.  
The cost for returning faulty goods is not covered under 
warranty.  
 
Additional agreements could be part of the contract of 
delivery.  
 
If any problem arises which could be subject of guarantee, 
procedures should be followed as described in the 
guarantee certificate, unauthorised repairs could lead to 
further damage and violate the guarantee conditions.  
 
 

Should work take place, which is not in 
accordance with the guidelines, instructions 
and specifications contained in this user’s 
manual and the supplementary installation 
manual, then damage may occur and the 
generating set may not fulfil its specifications. 
In all these cases the guarantee may become 
invalid. Use original spares only! 

 
 

1.4 LIABILITY 

Whisper Power does not accept responsibility for damage, 
injuries or casualties which are the result of operation of 
the generating set in specific conditions which brings 
dangers which could not be foreseen, or could be avoided 
by additional measures. Whisper Power does not accept 
liability for damage due to use of the generator, possible 
errors in the manuals and the results thereof.  
 

Automatic start/stop  

Whisper Power cannot be held responsible for 

damage caused by the unattended running generator 

using the auto-start/stop mode or interval mode. 

 

 
 

1.5 IDENTIFICATION 

 

1.5.1 General 

 

Before using this generating set it is very important to 
identify the set correctly. To communicate for service or 
ordering parts it is also essential to correctly identify the 
generating set. Also for the daily operation of the genera-
ting set it is necessary that the operator knows the correct 
specifications.  
 

1.5.2 Nameplate 

 

All required identification data are on the nameplate.  
 
1  The identity of the generating set is given by the 

SERIAL NUMBER.  

When this number is available the manufacturer can 
trace the specifications of the generating set. On the 
nameplate are also some basic features of the set: 

 
2 POWER 

The nameplate gives the nominal maximum load in 
kVA (= kW) calculated with power factor one. When 
calculating a load one should always take into 
account the power factor or cos phi of this load. The 
power should never exceed the nominal power in kW 
as shown on the nameplate. Power is rated at an 
ambient temperature of 25°C. For higher
