Installation
Planning the power of the electrical generator
Electrical generator
You must power on the generator before powering on the product.
Verify that the product is turned off before powering on the generator.
LA4X draws 10 A max from 230 V.
A typical generator has a power factor of 0.8 and should operate at 70% load for good efciency.
The kVA provision for one LA4X should therefore be:
(10 A x 230 V) / (0.8 x 70%) = 4.1 kVA
This calculation is an example using typical values. It can be adapted using the table in section Power consumption
(p.17).
Power cord
The removable power cord is tted at one end with a 20 A powerCON connector.
The other end and the wires color code depends on the cord type, as follows:
type plug live neutral ground
CE
CN
CEE 7/7, 16 A / 250 V, grounded
GB1002 GB2099, 16 A
brown blue green/yellow
US NEMA 5-15, 15 A / 125 V grounded black white green
INT bare ends (local power plug to be tted) black white green/yellow
Strictly apply the specic safety regulations of the country of use.
Do not defeat the ground connection of the supplied power cord using an adaptor or any other methods.
A suitable plug must be wired to the INT power cord.
Verify that the plug conforms to the specic voltage and current rating given in section Electrical specications
(p.15).
