Safety
Commissioning, operation and maintenance is only permitted for qualified and trained personnel.
Insofar as installation, commissioning or retrofit is carried out on energized equipment, the relevant safety
regulations must be adhered to.
When designing and mounting a panel for the first time an acceptance of the equipment must be carried out
together with Tavrida Electric in order to ensure the installation conditions.
The ISM must always be tested and operated together with the CM. Individual testing is not possible and
may lead to the destruction of the ISM.
Caution
Danger!
Tests at end of installation include at least:
· Check for damage
· Remove dirt
· Check bolted connections for fixing points, primary
terminals and earthing (also torques)
· Test special functions such as moving function,
mechanical interlocks and plug connections insofar
as ISM is mounted on a draw-out unit
· Check that for free air circulation at ISM is possible
Testing the rated insulation level to IEC 6094
and VDE 06701 Part 1000, ANSI C37.09:
· For 15 kV ISM the rated power frequency
test voltage is 36 kV (42 kV according to
the Chinese Standard GB 1984-2003)
· For 27 kV ISM the rated power frequency test
voltage is 60 kV
Commis s ioning Secondary Part
Preparation before testing the functionality include at least:
· Testing the availability of the CM auxiliary power supply. It is recommended to use the same auxiliary power supply
as for protection and control devices.
· Checking whether the correct type of voltage, the correct voltage level and for direct current the correct polarity
have been selected.
· Checking that the correct MCB has been installed.
· Checking that all secondary connections have been pulled up tight.
· Checking whether the optional interference suppressing filters have been installed and earthed (see chapter
“Installation, Secondary part, Interference suppressing filters (optional)“).
· Checking that the shielding of the secondary cables and the earth connection of the CM have been properly
connected to the earthing point nearby the CM or if applicable for actuator coil cable
· Checking whether the CM, ISM and the optional elements are connected according to the circuit diagrams.
