Switch-on conditions with water-cooled drives
Before switching on the drive for the first time, you must reduce the
conductivity of the de-ionized water circuit to < 1 µS. After filling the
re-cooling unit, switch it on for several hours before switching on the
drive. The conductivity reduction may also be necessary if the drive
has been out of service for an extended period (such as mainte‐
nance/revision times).

● Spanner or socket spanner (w/f 10)
