Installation instructions for mains wire-in protectors
Installation
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)
.
ESP D1 protectors have been designed to fit onto a
standard 35mm DIN rail
(see 3 - DIN Installation)
or within
a Furse WBX D enclosure.
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.

Alternatively, for three phase units, a remote display option
is available. Units can be installed within the power
distribution panel with the remote display mounted on the
front of the panel
(see 4 - remote display)
.
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 12 & 13 - Length of connecting leads)
. Gland the
enclosure onto the power distribution panel. Suitable
enclosures are available from Furse.
