1. Safety instructions
Installation and electrical connections of
equipments and control stations may only
be carried out by skilled electricians and
instructed personnel in accordance with
60079-14 and the respective national
legislation on electrical equipment for
explosive atmospheres.
This explosion protected equipments and
distributions must not be operated in
Zone 0 or 20 hazardous areas.
The requirements of EN 61241-0, -1 and
60079-0 regarding excessive dust deposits
and temperature must be considered by
the user.
The technical data indicated in point 3
as well as those indicated in the technical
documentation
supplied
equipment, must be observed.
It is necessary to ensure that the power
dissipation of equipment is not exceeded
(see technical documents supplied with
the equipment). The temperature class
and explosion group stated on the
equipment shall be observed. To ensure
adherence to the temperature class stated
on the type label of the equipment, the
permissible ambient temperature, the
rated terminal cross section and the self
heating of the equipment mainly due to
the power dissipation shall be taken into
account (test criterion for the self heating
is an overload of 10%).
Modifications or design changes to
equipment and distributions that affect
the
explosion
protection
permitted.
They shall be used for their intended
purpose and shall be in a perfect and
clean state.
Only original COOPER Crouse-Hinds
parts may be used as replacements and
for repairs.
Repairs
that
affect
the
protection may only be carried out by
COOPER Crouse-Hinds or by a qualified
electrician in compliance with the res-
pective national regulations.
Prior to being put into operation, the EFS
control stations shall be checked in
accordance with the instructions as per
section 6.
The operator is required to ensure that
the overall current of a distribution with
bus bar systems does not exceed the values
stated in the technical data of the
equipment.
Distributions mounted on a floor frame
shall be safeguarded against falling over.
Before initial operation, any foreign
matter shall be removed from the EFS
control stations, do not keep this
operation instructions not technical
documentation inside the equipment
during its operation.
