P50 Agile P153 Chapter 2 - Safety Information
P153/EN M/A 2-7
Warning:
The PCT is sometimes used to terminate cable screens. Always check the
PCT’s integrity after adding or removing such earth connections.
Warning:
Use a locknut or similar mechanism to ensure the integrity of
stud-connected PCTs.
Caution:
The recommended minimum PCT wire size is 2.5 mm² for countries whose
mains supply is 230 V (e.g. Europe) and 3.3 mm² for countries whose mains
supply is 110 V (e.g. North America). This may be superseded by local or
country wiring regulations.
For P60 products, the recommended minimum PCT wire size is 6 mm². See
product documentation for details.
Caution:
The PCT connection must have low-inductance and be as short as possible.
Caution:
All connections to the equipment must have a defined potential.
Connections that are pre-wired, but not used, should be earthed, or
connected to a common grouped potential.
3.6 PRE-ENERGISATION CHECKLIST
Caution:
Check voltage rating/polarity (rating label/equipment documentation).
Caution:
Check CT circuit rating (rating label) and integrity of connections.
Caution:
Check protective fuse or miniature circuit breaker (MCB) rating.
