14.3 Drying dampness

If the panels become damp by condensation or high humidity, e.g. prevailing during erection, they must be
dried. Use several electrical heaters of 1000 to 2000 W each. Alternatively, the anti-condensation heater must
be switched on if such is part of the switchgear.
The warm air has to flow through all compartments of the switchgear until the panels are completely dry. Take
the withdrawable part / switching-device truck out of the panel to support the air flow.

14.4 Instructing the operating personnel

Give the Operating Instructions with order number 110-0134.9 to the operating personnel in
good time.
Instruct operating personnel in theory and practice of switchgear operation.
Make sure that the operating personnel are familiar with all operational details when the
commissioning procedure takes place.
