F ) For Production as well as Consumption/PCS CTs, you must apply the
following label to each CT when the system is configured to use PCS-based
current limiting.
The available space on the CTs for labeling is as follows.
Consumption/PCS CT (CT-200-SPLIT):
• Left side: 20mm(vertical) x 14mm(Horizontal)
• Back side: 20mm (vertical) x 20mm(Horizontal)
Production CT (CT-200-SOLID):
• 9mm(vertical) x 30mm(horizontal)
This sensor is part of a Power Control System. Do not re-
move or disable. Replace with same type and rating.
NOTE
: The maximum operating currents in controlled busbars or
conductors are limited by the settings of the Power Control System
(PCS) and may be lower than the sum of the currents of the connected
controlled power sources. The settings of the PCS controlled currents
may be used for calculation of the design currents used in the relevant
sections of NEC Article 690 and 705.
*
WARNING!
Risk
of electric shock and fire. Only qualified personnel
are permitted to set or change the setting of the maximum operating
current of the PCS. The maximum PCS operating current setting shall
not exceed the busbar rating or conductor ampacity of any PCS con-
trolled busbar or conductor.
