5 STORAGE - HANDLING
STORAGE ENVIRONMENTAL CONDITIONS 5.1
If the OPDE DC-DC converter has to remain stored for a long time, it is necessary to store it in a safe environment
with an adequate temperature and humidity degree, and protected against dust.
TAB. 5 – Storage
EVERY 6 MONTHS – 1 YEAR, IT IS NECESSARY TO REGENERATE THE POWER BUS CAPACITORS.
FIRST IMPLEMENT THE RECOVERY PROCEDURE AFTER STORAGE (PAR. 5.2) WITH SWITCHED
OFF CONVERTER. THEN, FEED THE OPDE ENERGY THROUGH X3 (AUXILIARY POWER SUPPLY
FOR THE ADJUSTMENT SIDE) AND THE + AND - BARS (POWER SUPPLY OF THE POWER SIDE)
FOR AT LEAST 2 HOURS WITHOUT GIVING THE RUNNING CONSENT.
RECOVERY PROCEDURE AFTER THE STORAGE 5.2
The converter cannot be used immediately after a storage period. To prevent faults, it is necessary to adopt the
following recovery procedure.
PHASE 1: Let the converter stay for an hour under the environmental conditions specified in TAB. 6
(1)
After this recovery time, there should be no trace of
condensation inside or outside the converter (well ventilated
environment).
TAB. 6 – Recovery after storage
PHASE 2: If the time since the last regeneration of the electrolytic capacitors in the power bus is included between
6 months and one year, it is necessary to perform the regeneration once again: feed the OPDE DC-DC
through the terminal X3 (24 Vdc auxiliary power supply for the regulation side) and the + and - bars (560
Vdc power supply of the power side, by means of external precharge) for at least 2 hours without giving
the running consent.
Once the regeneration process has ended, the converter can work normally.
THE REGENERATION PROCEDURE OF THE POWER BUS ELECTROLYTIC CAPACITORS GIVEN
ABOVE IS NO MORE VALID IF:
THE TIME ELAPSED SINCE THE LAST REGENERATION IS GREATER THAN 1 YEAR
THE TIME ELAPSED SINCE THE PURCHASE IS GREATER THAN 1 YEAR AND THE
REGENERATION PROCEDURE HAS NEVER BEEN DONE
IN THESE CASES, IT IS NECESSARY TO REQUEST FROM BDF DIGITAL WHICH IS THE
OPERATING PROCEDURE TO BE ADOPTED.
HANDLING 5.3
The OPDE DC-DC converters size 175, 220, 250, 310, 370 and 460, after unpacking, are easily transportable with a
forklift truck or a crane equipped with suitable lifting hooks to be attached to the lifting brackets applied on the sides
of the converters. Dimensions and weights are given in Chapter 4. For OPDE DC-DC converters size 70, 90, 110 and
150, instead, there are no brackets for lifting. Given their limited size and weight, the converters can be transported
directly by the entrusted personnel.
Protect the equipment against bumps during handling.
