After installation and power-on, use a multimeter to check whether the voltage at the cabinet copper bar connected to the output terminal of the charger is within
the normal range (200
–500 V DC). Check that the green indicator on the charger is steady on, indicating that the charger is running properly.

Maintenance
To ensure that the charger can operate properly for a long term, you are advised to perform routine maintenance on it as described in this chapter.
•
The product has the maintenance-free class B and the MTTR of at most 1 h. The charger is hot swappable and should be replaced if it is faulty.
•
The air filter of the cabinet needs to be cleaned regularly to avoid dust buildup at the air inlet as dust can cause overheating inside the charger.
