6.2.1 Storage
If the system is not installed immediately upon receipt, it must be stored properly to prevent corrosion and deterioration. Since
packing cases do not protect the equipment for outdoor storage, the customer must provide a clean, dry place, free of
temperature variations, high humidity, and dust.
Use the following guidelines when storing the equipment:
• Place the equipment under adequate cover with the following requirements:
− Keep the equipment clean and dry, protected from precipitation and flooding.
− Use only breathable (canvas type) covering material – do not use plastic.
• Unpack the equipment as described, and label it.
• Maintain the following environment in the storage enclosure:
− Recommended ambient storage temperature limits for the Mark VIe controller are from -40 to 85°C (-40 to 185 °F).
− Surrounding air free of dust and corrosive elements, such as salt spray or chemical and electrically conductive
contaminants
− Ambient relative humidity from 5 to 95% with provisions to prevent condensation
− No rodents, snakes, birds or insects
− No temperature variations that cause moisture condensation
Attention
Condensation occurs with temperature drops of 15°C (59 °F) at 50% humidity over a four-hour period, and with smaller
temperature variations at higher humidity.
If the storage room temperature varies in such a way, install a reliable heating system that keeps the equipment temperature
slightly above that of the ambient air. This can include space heaters or cabinet space heaters (when supplied) inside each
enclosure. A 100 W lamp can sometimes serve as a substitute source of heat.
Attention
Installation Guidelines
Moisture on certain internal parts can cause electrical failure.
To prevent fire hazard, remove all cartons and other such flammable materials packed
inside units before energizing any heaters.
