11 System and Safety
Device Maintenance
In order to ensure that your system functions properly and has a long service life, per-
form the following checks after commissioning and then on an annual basis.

Check and re-tighten all connections. Screw connections may become loose at the
beginning due to thermal stress.

Check fuses, safety devices and switching equipment.

Check the control performance in automatic mode.
 Check the cooling air setting (fans, temperature monitoring function):

Check that the controller temperature relay switches the fans on at 28 °C.

Check that the temperature monitoring switches the system off via controller at 48 °C.

Clean the filter mats if necessary, depending on how dirty they are.
 Perform a visual inspection of the capacitors.

Examine the current input and capacitor terminal voltage once every three months.

Check the reactive energy consumption on the basis of the electricity bill.
NOTE
The current consumption and the temperature of these systems must be checked reg-
ularly so that overloading of the capacitors can be detected at an early stage. Excessive
current consumption can be caused by an increasing proportion of harmonics or by
faulty capacitors.
