Altitude and derating
In area where altitude exceeds 1000 meters, MONT72 should be derating since the heatsink efficiency
will be reduced because of the tenuous air.
The rated value of output current derates by 1% for each 100m increase of the altitude. I.e for the
altitude of 3000m, derated rate is 20% for rated current of MONT72. Figure 1-1 is the derating curve of
rated current and the altitude.

1.4 Maintenance
Due to environmental temperature, humidity, pH, dust, vibration and other factors, as well as the aging
and wear of the device inside the drive controller, etc., it will lead to potential failures. Therefore, the
controller must be stored and used. Daily or regular maintenance.
• If the drive controller is transported over long distances, it should be routinely checked before use
to confirm that the product components are complete and the nails are fastened.
• During the use of the drive controller, the internal dust of the drive should be cleaned regularly.
Check the internal fastening screws to make sure there is no looseness.
•
MONT72 can only be maintained by qualified and trained professionals.
•
Maintenance personnel must remove the metal jewelry before maintenance. Maintenance must use clothing and
tools that meet the insulation requirements.
• The MONT72 is in a live, running, dangerous high voltage inside.
• Before checking and maintaining the MONT72, disconnect the input power reliably and wait at least 10 minutes.
Check that the MONT72 internal charge indicator is off and the voltage between the power terminals (+) and (-) is
lower than 36V. In order to open the MONT72 cover for maintenance.
• For drive controllers that have been stored for more than 2 years, the regulator should be slowly boosted by the
regulator during the first power-up.
•
Do not leave metal objects such as wires, tools, and dowels inside the drive controller.
•
Do not modify the drive controller without authorization.
•
There are static-sensitive IC components inside the drive controller. Do not touch the on-board device directly.
