Installation

3.1 Location
Protectors need to be installed very close to the power
supply to be protected. Usually the protector will be
installed at a power distribution panel either inside it
(Figure 1) or right next to it (Figure 2).
3.2 Enclose the ESP unit
The ESP unit has exposed terminals. For electrical safety,
the unit must be installed within a panel or enclosure. For
standard single and three phase units, where possible,
install the unit within the power distribution panel
behind a suitable viewing window.
