2. Installation.
2.1. Requirements.
The DC/DC converter is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required
for a given country) for step down installations. The module should be mounted in confined spaces with normal relative humidity
(RH=90% maximum, no condensation) and temperature range from -10°C up to +40°C. The module should operate in vertical position
in order to provide free and convectional air flow.
Proper operation of the module requires adequate current capacity of the power source; the power supply capacity should be
calculated using the formula below:
PIN = 1,15 x PAUX
(PIN = 1,15 x IAUX x UAUX)
The module's load balance should be
done prior to installation. During normal
operation, the total current of the receivers should
not exceed I=5A while the power drawn from the
module should not exceed Pmax=60W, as shown
in the Fig. 3.
