POWER DEFINITION

PRP : Prime Power is available for an unlimited number of annual

operating hours in variable load applications, in accordance with ISO

8528-1. ESP : The standby power rating is applicable for supplying

emergency power in variable load applications in accordance with ISO

8528-1. Overload is not allowed.

TERMS OF USE

According to the standard, the nominal power assigned by the genset is

given for 25°C Air Intlet Temperature, of a barometric pressure of 100

kPA (100 m A.S.L), and 30 % relative humidity. For particular conditions

in your installation, refer to the derating table.

ASSOCIATED UNCERTAINTY

For the generating sets used indoor, where the acoustic pressure levels

depends on the installation conditions, it is not possible to specify the

ambient noise level in the exploitation and maintenance instructions .

You will also find in our exploitation and maintenance instructions a

warning concerning the air noise dangers and the need to implement

appropriated preventive measures.
