Transport and storage of electronic equipment

In general you should consider the expediency of storing electronic equipment as backup. The suppliers are often able to repair / exchange within a short time. Even if you have to pay express fee and transport it often gives a good payoff as you secure an operational device that is covered by warranty! At the same time expenses to finance the stock and unsaleability is eliminated.

Still some companies choose to have electronic equipment on stock to secure production.
Therefore it is frustrating when you connect your “new” equipment and it does not work! The reason for this is often:

Wrong conditions during transport and/or storage
Units contain electrolytic capacitors / batteries

Below you will find an example of a specification for a servo drive:

Transport

Temperatur	-25 … 70 oC
Relative humidity	5…95 %, climatic category 2K3
Absolute humidity	1…60 g/m3, climatic category 2K3
Moisture condensation	Not allowed
Icing	Not allowed
Shock test non operating EN60068-2-27	alf sine in 3 axses: 10g / 11 ms

Storage

Temperatur	-25 … 55 oC
Relative humidity	5…95 %, climatic category 1K3
Absolute humidity	1…29 g/m3, climatic category 1K3
Moisture condensation	Not allowed
Icing	Not allowed

If the unit contain rechargeable batteries and/or electrolytic capacitors, we recommend circulating stocked units with operational units on the machine once a year. If circulation is impossible, the unit should be connected to power (remember all supply voltages) once a year for 24 hours.

If the unit contain non rechargeable batteries, you should remove them from the unit – alternatively change them once a year to prevent leakage from the batteries.

BEC offers systematic preventive maintenance of electronic controls including the above mentioned.
