AIR VENTS OVER THE CABINET FANS MUST NOT BE BLOCKED BY ANY
MEANS DURING OPERATION OF THE SYSTEM, AND AT TEMPERATURES
OVER 20°C, THE FANS MUST DEFINITELY BE CHECKED TO MAKE SURE
THEY WORK PROPERLY.
CAUTION!
The rules that must be obeyed strictly upon switching the system on and off are stated as a
separate chapter at the end of this guide.
In case the system consists of three or more racks, if they are turned on and off by the
battery switches, then those switches are damaged in time, due to electric arcs. In order to
avoid this situation, a delayed main battery breaker (10 A 250 V Main breaker) has been
included in the system. Control of the electricity supplied to the racks from the battery is
provided through that breaker. Detailed information about this is in the next section of this
guide.
