3.2.3 Control panel installation
Figure 28: Control panel dimensioning
Calculation of control panel surface:
When installing a DC1 frequency inverter with protection type IP20 in an
enclosed installation enclosure (in order to get a higher protection type in the
case of a “local installation“, for example), the following minimum clear-
ances are required:
A=
P
V
[m
2
]
ΔT x K
A = Control panel surface [m
2
] calculated according to IEC 890)
P
V
= Total heat dissipation [W] of all fitted devices
T = Temperature difference [K], (default value = 5.5 K)
K = Heat transfer coefficient [W/(m
2
xK)]
(standard value = 5.5 for steel control panels)
