1.13.5. Storing GEM
80 Before Installation
Equipment which is not required for immediate installation should be stored in
a clean, dry atmosphere at a reasonably constant temperature (-25 to +70°C).
To minimise the ingress of fine dust, the equipment should be covered with a
suitable canvas, tarpaulin or heavy duty polythene sheet. Any loose
equipment should be kept in the original packing, which should be resealed
after the delivery inspection.
Where equipment is unavoidably subjected to high humidity (e.g. for short pre-
commissioning periods during installation in a humid location) it is
recommended that the cubicle be fitted with anti-condensation heaters and
the equipment be thoroughly dried out prior to the first application of power.
Such heaters should then be automatically switched on whenever the GEM
80
equipment is subsequently shut down.
Some GEM
80 modules contain electrolytic capacitors which degrade if the
system is not powered up. Where inactive storage times are expected to be in
excess of 9 months, the shelf life of electrolytic capacitors may be exceeded,
it is essential that units with electrolytic capacitors (power supplies and some
Compact I/O Modules) are powered up every 9 months.
1.13.6. Radio Frequency Interference (RFI)
This section is intended as a guide for users who wish to operate Cegelec
Industrial Controls Ltd electronic products in the vicinity of a radio transmitter.
The transmitter may be of the static or the hand-held portable type.
Unrestricted use of a transmitting device could result in a malfunction of the
equipment. This in turn could cause a breakdown of plant equipment and
injury to personnel. Cegelec Industrial Controls Ltd products are designed to
function satisfactorily within a RFI field strength of 10V/m over a frequency
range of 30MHz to 1GHz.
