Electrical parameters for determining cable cross-sections

◗ the battery current values and cable

cross-sections have been determined

for a battery at the end of a charge

cycle;

◗ the current values and cable sections

for Mains 2 and load are given for full

rated load with a power factor of 0.8.

(1) the rated Mains 1 currents (In) have been

determined for a minimum float charging voltage of

423V and full rated load with a power factor of 0.8.

(2) the cable cross-sections are given for copper

conductors. They are calculated according to

permissible temperature rise and allow for line

voltage drops over a maximum length of 100 m

(AC circuits) or 25 m (DC circuits if cables not

provided). For greater lengths, the cross-sections

should be chosen to limit voltage drops to 3% (AC)

or 1% (DC).

◗ this table has been drawn up for

rated phase-to-phase Mains and load

voltages of 415V. For voltages of 380V,

multiply the currents for Mains 2 and

load by 1.09; for voltages of 400V, use

the table in another language version of

this manual;

◗ the current values and cable cross-

sections for Mains 1 are given for full

rated load with a power factor of 0.8

and a battery consuming its minimum

float charging voltage;

For frequency converters, the

parameters concerning Mains 2 are not

applicable.

The load parameters common to all the

converters are given in the table below.

For a parallel UPS, the parameters for

Mains 2 and load are also provided in

the table below.

For a modular UPS, the parameters

for Mains 2 and load are also

provided in the table below.

Characteristics (cont.)

NF C 15-100 authorizes a maximum of 4

cables per phase.

(1) the indicated heat losses are those produced

by the unit at full rated load and with the battery

float charging. They must be taken into account

when dimensioning the air conditioning system.

The cubicles are cooled by forced ventilation.

The air enters via the doors and grids at the bottom

and is discharged via the roof.
