Installation of the device
 Position the device on level surface and hard subgrade only. The locking device of the wheels is
not appropriate to put the device on hilly ground.
 Only operate the device in sufficiently large and ventilated compartments (room volume > 100 m³)
so that the admissible SF
6
concentration in ambient air is not exceeded in case of leakages
incurring suddenly.
 For operation in smaller compartments SF
6
warning devices must be available as well as the
possibility to leave the compartment quickly.
 In case the device is burning the pressure vessel must be cooled down to prevent an
inadmissible high increase in pressure.
Personal protective equipment for operating personnel
 Safety gloves which allow the operation of the electrical operating elements.
 Ear protection is recommended for all devices with a sound power level of > 80 dB(A). As from 85
dB(A) the use of ear protection is compulsory.
 Safety shoes
 Wearing safety goggles is necessary in case hoses and tubes which are under pressure are
opened (e. g. cylinder threads on SF
6
-gas bottles), as gas or fluid jet could escape.
Basic safety measures during maintenance
 Follow inspection and maintenance periods described in the operating manuals.
 Follow maintenance and repair instructions for individual components in these operating
manuals.
 Prior to carrying out maintenance and repair works turn off the main switch for the power supply
and secure it with a padlock. The key for this lock must be in the hands of the person who carries
out the repair works.
 If there is no main switch unplug the power supply cable at the plant and secure against it being
plugged back in.
 When exchanging heavy machine parts only use suitable lifting devices in good working
condition. Heavy components are to be secured against falling down by proper facilities.
 Prior to carrying out maintenance or repair works ensure that parts which may need to be
handled have cooled down to room temperature.
 Dispose of grease, coolant or cleaning material in accordance with environmental regulations.
 If a device has been contaminated with SF
6
decomposition products additional safety measures
are to be taken. Furthermore protective clothing and a dust mask depending on the degree of
contamination is required.
 The working protection set is available under the order number: 3-442-R001.
