4 Installation and Configuration
4.1 Unpacking
Upon receipt of the materials it is recommended to check immediately the integrity of the packing and their
contents.
If there is any indication or evidence of shipping damage the equipment should not be moved or unpacked.
Moving the equipment to a remote storage or holding area may unfavourably affect the owner’s shipping insurance
protection.
The receiver should promptly and properly report to the shipper supplying all necessary information.
If instruments are not for immediate use it is recommended that you check that all characteristics shown on the
instruments label meet order specifications (model, supply voltage and frequency, input/output range, certification,
tag, etc.) as well as the actual application requirements
If not installed, the equipment should be stored following recommendations in next paragraph, Storage.
4.2 Storage
In case of storage of instruments and accessories proper care should be taken to protect from any possible
damage.
Always store instruments in their sealed original packaging until they are installed. Provide adequate protection to
prevent damages that may be caused by exposure to:
•
rain, excessive humidity and/or temperature excursions (inadequate sheltering)
•
dust (build-up of a corrosive patina that may cause oxidations and reduce isolation)
•
aggressive and polluting atmospheres (SO2, H2S, mists, salts, smokes, etc.) with consequent corrosion
•
access by insects/rodents (damage of packing or content)
•
mechanical shocks or unauthorised packing opening
•
intense vibrations (loosening of fastened parts, fatigue failure)
•
any other possible risk
Make sure the storage temperature does not exceed the limits of -20 to +70
°
C (-4 to 158
°
F) for medium/long
term storage (days/months) and -25 to +75
°
C (-13 to 167
°
F) for short term (a few hours) transportation/shipment.
When inspection is completed, pack instruments in their original packing, seal plastic bags including any desiccant
bags (i.e. silica gel) intended for humid environments.
List the contents on the packaging to avoid unnecessary further inspections.
4.3 Operating environment
HiD series instruments can operate on wide temperature and humidity ranges. Practical considerations suggest
however, limiting the environmental stress, thus increasing both reliability and availability.
As for temperature and heat dissipation, please refer to the detailed discussion in section 4.9 and 4.10.
As for humidity dust and vibration, some simple guidelines are given in the following.
High humidity (above 60% RH) creates, especially in conjunction with corrosive atmosphere, chloride or sulphide
condensation when the ambient temperature drops a few degrees. This corrosive film tends to accumulate and
concentrate at each temperature cycle on the boards, thus affecting its isolating properties and increasing contact
resistance.
Accumulation of dust on circuit board facilitates corrosion in humid environments producing effects similar to that
of a corrosive atmosphere.
Excessive permanent vibration can induce component stress affecting connector contact quality and inducting
fatigue failures on vibration sensitive components.
