IMPORTANT SAFETY INSTRUCTIONS
WARNING !
Configuration of the power control settings system or changes to settings shall be
made by qualified personnel only. Incorrect configuration or setting of the power
control settings may result in unsafe conditions.
WARNING !
The controlled current settings shall not exceed the busbar rating or conductor
ampacity of any PCS controlled busbar or conductor.
WARNING !
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.
