Preparations
If not be done before measurement the following steps are necessary:
•
switch system de-energized
•
secure against restart
•
await one minute for discharge of the capacitors
• clean sine-wave filter from dust and other contaminations
2.5.3
Disassembly of the old capacitors
•
remove heat-shrinkable tube with knife
•
unscrew connection cable
• remove fixing bolts
•
remove capacitor
•
execute insulation test in accordance with 2.4.3 (if required)
2.5.4
Installation of new capacitors
•
insert capacitor
• tighten fixing bolt in accordance with table 2.5.1
•
pull heat-shrinkable tube over the connection cables
•
tighten connection cable in accordance with table 2.5.1
•
lock heat-shrinkable tube with hot-air fan
2.6
Disposal
The capacitors are lead-free and use M-DBT as dielectric. Disposal of old capacitors must
be done in accordance with the local regulations.
