Intended Use

The Rapid Shutdown System consists of one or more Rapid Shutdown Boxes and one Rapid
Shutdown Controller. PV systems equipped with the Rapid Shutdown System satisfy the
requirements of the National Electrical Code
Controller activates and deactivates the Rapid Shutdown System and signals the status of the Rapid
Shutdown System via the green and red LEDs. The Rapid Shutdown Box electrically discharges the
PV generator conductors from the Rapid Shutdown Box to the inverter within ten seconds of
activation of the emergency switch on the Rapid Shutdown Controller to ≤30 V. When the
irradiation on the PV array is sufficient and the voltages have been electrically discharged in
accordance with specification, the green LED on the Rapid Shutdown Controller glows green
constantly. When none of the LEDs of the Rapid Shutdown Controllers are glowing after actuating
the emergency switch, either the irradiation on the PV array is too low and, thus, the supply voltage
of the Rapid Shutdown System insufficient or the installation of the Rapid Shutdown System is faulty
or the Rapid Shutdown Box is defective.
The product is suitable for indoor and outdoor use.
The product is certified for use in PV systems with the following SMA inverters:
• SB 3000TL-US-22 / SB 3800TL-US-22 / SB 4000TL-US-22 / SB 5000TL-US-22 /
SB 6000TL-US-22 / SB 7000TL-US-22 / SB 7700TL-US-22
• SB3.0-1SP-US-40 / SB3.8-1SP-US-40 / SB5.0-1SP-US-40 / SB6.0-1SP-US-40 / SB7.0-1SP-
US-40 / SB7.7-1SP-US-40
Use of the product in PV systems with inverters of manufacturers other than SMA is not permitted.
