Safety information shall be provided in the maintenance manual including, as appropriate, the
following:
• preventive maintenance procedures and schedules;預防維修程序及期間
• safety precautions during maintenance (for example, the use of earthing switches for highvoltage
PDS);
• location of live parts that can be accessible during maintenance (for example, when covers
are removed);
• adjustment procedures;
• subassembly and component repair and replacement procedures;
• any other relevant information.
NOTE 1 These may best be presented as diagrams.

6.5.2 Capacitor discharge 電容放電警告
When the requirements of the first sentence of 4.3.11 are not met, the warning symbol
IEC 6041-5036 (2002-10) 7 (see Annex H) and an indication of the discharge time (for
example, 45 s, 5 min) shall be placed in a clearly visible position on the enclosure, the
capacitor protective barrier, or at a point close to the capacitor(s) concerned (depending on the
construction). The symbol shall be explained and the time required for the capacitors to
discharge after the removal of power from the PDS shall be stated in the installation and
maintenance manuals.

6.5.3 Auto restart/bypass connection 自動啟動說明

If a CDM/BDM can be configured to provide automatic restart or bypass connection, the
installation, user and maintenance manuals shall contain appropriate warning statements.

A PDS which is set to provide automatic restart or bypass connection after the removal of
power shall be clearly identified at the installation.

6.5.4 PT/CT connection PT/CT連接說明
A PDS which has monitoring or control functions using a potential transformer (PT) supplied
from high voltage, or a current transformer (CT) supplied from a high current connection, shall
be clearly marked to show the possible hazards of voltage transients upon disconnection of the
secondary circuit. The hazards shall also be described in the installation and maintenance
manuals.

6.5.5 Other hazards 其他危險
The manufacturer shall identify any components and materials of a PDS which require special
procedures to prevent hazards.
