ATTENTION:

The waste heat of the UPS must be dissipated!

The ventilation of the battery compartments must be carried out in

accordance with DIN/VDE 0510, Part 2. The following general rule is

applicable for ventilation requirements (for lead-acid batteries):

Q = 0.05 x n x I / 2

with: Q = air volume in m

n = number of lead-acid cells

I = amperage

The ambient temperature in the battery compartment should not

exceed 20 °C, as the service life of the batteries is otherwise

considerably reduced.

4.5 Floor Mounting

Four holes are provided in the base frame of the UPS for the fixing

bolts. The spacing and diameter of the bores can be found in the

table below.

Before securing the UPS to the floor, ensure that it is vertically

aligned, and compensate for any unevenness (e.g. using metal

wedges).
