HOUSING
The EV-UV detector may also be used with the NITTAN NFD-FPH
Flameproof housing. The NFD-FPH is for use in areas made
potentially hazardous by the presence of flammable liquids or
vapours (zone 1 or zone 2).
The housing has a threaded cover to enable ease of access for
installation and includes internal and external earth terminals
suitable for up to 4mm sq. cable. The EV-UV, when installed in the
NFD-FPH, requires a special bracket and base inside the housing to
enable correct mounting of the flame detector - this is included in
the housing.
