1.8 Maintenance and inspection
RAMO and RASP are maintenance-free if the general rated operational data
(
Table 2, page 19) and the specific technical data and version particulars
( ￫ Section “5.4 Special technical data”, page 122, and Page 136) are
observed. External factors can, however, influence the component’s lifespan
and function. We therefore recommend that regular checks and the follow-
ing general maintenance measures be performed at the specified intervals.

It is not intended to replace or repair individual RAMO5 or RASP5 assem-
blies.
Internal DC link capacitors in RASP5
After longer storage periods or longer downtimes without power supply
(> 12 months) the capacitors in the the DC link must be charged in a guided
manner in order to avoid damage.
For this the RASP5 must be fed with a regulated DC power supply unit via
two mains connection terminals (e. g. L1, L2). In order to prevent the capaci-
tors from having excessively high leakage currents, the inrush current should
be limited to approximately 300 to 800 mA (depending on the relevant rat-
ing). RASP5 must not be enabled (no start signal).
Then set the DC voltage to the values of the corresponding DC link voltage
U
DC
and supply it for approx. two hours (regeneration time), approx.
565 V DC (= 1.42 x U
LN
) For a three-phase phase voltage of 400 V.
Maintenance measures Maintenance interval
Clean cooling vents (cooling slits) - RASP5 only as needed
Check the fan function - RASP5 only 6 - 24 months (depending on the environment)
Check connectors (AS-Interface, sensors, mains, motor,
etc.) and all metallic surfaces for corrosion 6 - 24 months (depending on the environment)
Charge capacitors, only for storage of RASP5 12 months
￫ Section “1.10 Service and warranty”, page 30
STO function (RASP5 with STO input only) Activate and deactivate STO at least once every three
months.
