limits and voltage requirements.
Avoid locating the unit in areas where there may be extreme temperatures, harmful gases, unstable
voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic interference (e.g.,
large radar stations, transformer substations). Avoid areas that are prone to impounded water,
soaking, leakage, or condensation.
3.2.2 Spacing
Another consideration for planning where to install the SmartUPS unit is space allowance. Follow the
guidance shown in Figure 3-1 concerning the amount of space to leave on each side, front, and back
of the unit.

3.3 Lightning and Grounding Protection
Caution: Baicells recommends testing the SmartUPS on the ground before installing it on a
tower or other structure that may be difficult to reach.
You must protect the SmartUPS against lightning and other types of electrical overload. Follow the
ground cable specifications in
Table 3-1. You will need to make the grounding cable based on the
specific installation site where the SmartUPS will be installed. Use yellow-green wire that is no
smaller than 5AWG. The wire should be no smaller than 16 mm

.
Grounding notes:
 Ground as close to the device as possible.
 The Outdoor SmartUPS connects to a reliable outdoor grounding point (earth) through one
ground screw.
 The connection of the grounding points and the ground bar need to be tight and reliable.
Rustproofing the terminals is required. This can be done with rust preventing paint,
