Pre-installation
5.2.3 Provide heat dissipation
Table: 5.2 Indicative values for heat dissipation
1. Make sure that the heat dissipation efficiency is better than 90% for an equipment less than 30kVA and at
least 92% for a 30kVA equipment.
5.2.4 Ventilation
1. Make sure that you do not block the ventilation grids (A) of the
equipment.
5.2.5 External fuse
1. Install the external fuse in the distribution panel with at least one rating higher than the manual switch
(see § 7.7) for fuses type gG or aM.
5.2.6 Circuit breakers
1. If you use circuit breakers, make sure they are of the type D, or an equivalent type.
This means that the
magnetic trip current must be from 10 up to 14 times higher than the nominal current.
2. If you install more than one circuit breaker close to each other, make sure that you take into account the
thermal derating to maintain the selectivity.
Equipment [kVA] Heat dissipation [W]
2.5 250
4 400
5 500
7.5 750
10 900
15 1200
20 1400
25 1750
30 1800
Note
The necessary heat dissipation also depends on the input voltage range and on the
ambient conditions.
CAUTION
If there is not enough air-flow, the
components of the equipment become too
hot.
