When mounting the units in existing metal panels or
enclosures, ensure that the enclosure is securely bonded
to the earth bar to which the ESP unit will be connected.
If it is not possible to install the unit within the
distribution panel it should be mounted in a separate
enclosure, see Figure 2, as close as possible to the
distribution panel (see 3.9 - Length of connecting leads).
Gland the enclosure onto the power distribution panel.
Suitable enclosures are available from Furse.
