The power supply and control cabling for the intrinsically safe relay is included in the
delivery and it should be provided for by the customer (if not agreed otherwise in the
contract).
b) The flange packing
(gasket) must be used between the flange of the protected
device and the membrane, which is sealed to the flange of the FLEX device. This
gasket can be supplied by the company RSBP spol. s.r.o. according to parameters fit
for the particular installation. However, the customer can get it by himself/herself. The
gasket is shown in fig. 12 and 13. The gasket supplied by the company RSBP spol. s
r. o. is made of the EPDM material, which can be used in all common applications
with the ambient temperature between -
40 °C to 80 ° C all the time. For the
application with special requirements for the features of the gasket, we can supply the
gasket made of the material that meets the requirements. In the event that the
operator decides to use his/her own gasket, neither the supplier nor the manufacturer
is responsible for the problems related to the its inappropriate selection.
c) The protective bag
is intended to cover the functional area of the FLEX flame filter,
so that any penetration of foreign particles in the filter meshes reducing the
functionality of FLEX is prevented. The protective bag is recommended for the use in
dusty premises with the significant clogging risk of the flame filter. In the event of
explosion, the bag breaks and the energy is absorbed without any disturbance.
However, if the bag is damaged, either during the explosion or otherwise, it must be
replaced with the new one.
