Ship Kit Changes
If the DC power option is ordered, two DC power connector cables are provided
with each controller tray for connection to centralized DC power plant equipment.
Two additional DC power connector cables should be ordered if additional
redundancy is required.
Caution –
A qualified service person is required to make the DC power connection
per NEC and CEC guidelines. A two-pole 20-amp circuit breaker is required
between the DC power source and the array module for over-current and short-
circuit protection. Before turning off any power switches on a DC-powered module,
you must disconnect the two-pole 20-amp circuit breaker.
DC Power LEDS
The following table lists the LEDs for DC power.
DC Power Caution When Link Rate Switching
Caution – Change the Link Rate switch only when there is no power applied to the
controller tray. The link rate setting is read only at power-on. Before turning off any
power switches on a DC-powered tray, you must disconnect the two-pole 20-amp
circuit breaker.
