7.4 Commissioning the Frequency Converter
The frequency converter parameters are preset. Adjustment of parameters to suit operating condi‐
tions on site is done by trained and authorised personnel.
Changes to the factory settings may influence the whole machine. The machine may break down
or be damaged.
➤ Allow only trained and authorised personnel to make parameter changes.
7.5 Filling with cooling oil
The machine must be charged with cooling oil prior to commissioning, see chapter 10.15.
For the required cooling oil charge volume please see chapter 2.10.
7.6 Filling cooling oil into the airend
Before starting the compressor for the very first time and before re-starting after a shutdown period
of more than 3 months it is necessary to manually add a quantity of cooling oil into the airend. In
order to avoid that the cooling oil exceeds the permissible level, drain the required quantity from
the de-pressurised oil separator tank.
Chapter 10.16 provides detailed information on how to drain cooling oil from the oil separator tank.
