Dehumidifier

Place a suitably sized bag of desiccant material (silica gel or

similar) into the unit to keep the electronic components as dry as

possible.

Coatings

Spray the unit externally with a corrosion inhibitor (e.g. a light

oil) before packing.

Re-packing

The unit should be stored and transported in its original packing

material and/or crate. In the event that this material is not

available, proceed as follows:

• Small units must be protected from damp by being placed

within a plastic bag at least 0.15 mm thick. An appropriate

quantity of desiccant material should be placed inside this

bag, and the bag sealed. The sealed unit must then be placed

in an appropriate carton or crate, and supported in the

container by appropriate shock-absorbing insulation

(polystyrene foam chips etc.).

• Large units must be placed in a suitable cardboard box or

wooden crate. The unit must be protected against physical

damage by means of shock-absorbing insulation mats. The

box must be clearly marked with its contents, and must be

stored in a dry and dust-free area.

ESD precautions

Electrostatic Discharge (ESD)

Electro-Static Discharge (ESD) is the transfer of an electrostatic

charge between two bodies at different electrostatic potentials,

caused either by direct contact or induction by an electrostatic

field.

The passing of a charge through an electronic device can cause

localised overheating, and it can also “puncture” insulating

layers within the structure of the device. This may deposit a

conductive residue of the vaporised metal on the device, and

thus create a short circuit. This may result in a catastrophic

failure, or degraded performance of the device.

ESD Protection during transport and storage

Sensitive electronic equipment must be transported and stored in

protective packing bags, boxes and cabinets. The equipment

must NOT be transported or stored close to strong electrostatic,

electro-magnetic or radioactive fields.
