We recommend that all units are installed such that they are not subjected to direct sunlight, nor to large tem-
perature fluctuations which may give rise to condensation.
3.1.5 Service conditions
The relay is designed for use in industrial environ-
ment, for installation in standard relay rooms and
compartments so that with proper installation
elec-
tro-magnetic compatibility (EMC)
is ensured. The
following should also be heeded:
--- All contactors and relays which operate in the
same cubicle or on the same relay panel as the
digital protection equipment should, as a rule, be
fitted with suitable spike quenching elements.
--- All external connection leads in sub-stations from
100 kV upwards should be screened with a
screen capable of carrying power currents and
earthed at both sides. No special measures are
normally necessary for sub-stations of lower volt-
ages.
--- It is not permissible to withdraw or insert individu-
al modules under voltage. In the withdrawn condi-
tion, some components are electrostatically en-
dangered; during handling the standards for
electrostatically endangered components must
be observed. The modules are not endangered
when plugged in.
WARNING! The relay is not designed for use in resi-
dential, commercial or light-industrial environment
as defined in EN 50081.
