Preparation
DANGER - Risk of electric shock from dan-
gerous voltage!
Electric shocks resulting from contact with
live parts (e.g. main switch, printed circuit
boards) can cause injury, heart failure and
fatality.
¶ Work on electrical systems or equipment
must only be performed by qualified elec-
tricians or trained personnel under the
guidance and supervision of an electrici-
an.
¶ Secure the main switch so that it cannot
be switched back on.
¶ Unplug the mains plug or disconnect the
EPS 708 from the mains before opening.
1. Switch off the EPS 708 at the main switch.
2. Secure the main switch so that it cannot be swit-
ched back on.
3. Unplug the mains plug or disconnect from mains
electricity.
4. Remove the side cover for the electric compartment
(see Fig. 6, item4).
5. Check that there is no power.
6. Remove the rear cover for the electric compartment
(see Fig. 7, item3).
7. Remove the rear cover for the test oil compartment
(see Fig. 7, item4).

DANGER - Risk of electric shock from dan-
gerous voltage!
Electric shocks resulting from contact with
live parts (e.g. main switch, printed circuit
boards) can cause injury, heart failure and
fatality.
¶ After switching off the unit, wait 5 minu-
tes to allow the charged capacitors in the
frequency converter to discharge.
¶ Before starting to work, measure the
electrical voltage at live components to
ensure that the frequency converter can
be touched safely.
WARNING – Risk of burns from hot surfaces!
Touching the hot frequency converter
(>60 °C) poses the risk of burns.
¶ Do not touch the frequency converter
without wearing gloves.
¶ If the frequency converter is hot, wait 15
minutes until it has cooled down.
1. Open the cover of the frequency converter A13
(see Fig. 102, item 1).
2. In the frequency converter, remove the two covers
over the terminals.
