1. Label and warnings
a. Install the RSD on the roof, within ten feet of the PV array.
b. Note that the RSD may be installed at any angle from horizontal to vertical.
c. Note the temperature (-40oC to 75oC) and enclosure ratings (Type 4X) listed on product label attached to the RSD.
d. Choose a location where the maximum ambient air temperature will be less than the 75oC specifed maximum temperature.
While exposure to direct sunlight is permitted; installation under a module is preferred.
e. Ensure there is sufcient working area around the RSD to allow easy access for maintenance and/or service of the PV
system. If installing the RSD under a PV module, place it under the rst or last module in a row for access. Never install
the RSD in a location that would require the removal of multiple PV modules in order to gain access.
f. Note that the RSD power supply may already be inside the photovoltaic inverter wiring box.
3. RSD installation location
4. Mounting the RSD
5. Wiring the RSD input (from PV array) and output (to inverter)
a. Ensure the inverter's external AC disconnect and its integrated DC disconnect are turned OFF (open). Use appropriate
PPE, and use insulated tools when working with this equipment.
b. Ensure the EGC from the array is indeed connected in the inverter: The equipment grounding conductor (EGC) must
connect the inverter and array in order for the inverter’s ground fault protection to operate as required. (The RSD
enclosure itself is polycarbonate and does not require bonding.)
c. Refer to local codes for appropriate wire size on all conductors.
d. Locate the input wires (D) on the side of the RSD device marked "Input". This marking is present near the edge of the
RSD device on the front and back side. Connect the RSD input wires (D) to the PV array. The positive end of the PV
array must be connected to the RSD input wire labeled (+). The negative end of the PV array must be connected to the
RSD input wire labeled (-). (Note that there will be voltage on the PV array at this point.)
e. Locate the output wires (E) on the side of the RSD device marked "Output". This marking is present near the edge of the
RSD device on the front and back side. Connect the RSD output wires (D) to the inverter inputs. The RSD output wire
labeled Inverter (+) must be connected to the positive DC input terminal of the inverter. The RSD output wire labeled
Inverter (-) must be connected to the negative DC input terminal of the inverter.
WARNING: Swapping the input and output connections of the RSD device may make the system non-compliant
and/or create a hazardous situation. Therefore extra care must be taken to ensure proper connections of the input
and output wiring of the RSD device.
Safety and Hazard Symbols
Risk of electrical shock. Hazardous voltage
will cause severe injury or death. No user-
serviceable parts inside. Only trained service
personnel are allowed access.

6. Prepare to install the 24Vdc power supply
a. Conrm the inverter output (grid connection) is three-wire 240V line-to-line or two-wire 208V line-to-line inverter output.
The RSD unit is NOT compatible with a 277V grid connection. It must only be used with a 208V or 240V grid
connection.
b. Conrm all items in the RSD kit are accounted for; two 3-position terminal blocks and one terminal block cover (Figure
4), 24Vdc power supply and three short conductors to connect the power supply to the inverter AC terminals and to
ground. The 24Vdc power supply, terminal blocks, terminal cover and AC conductor cable will be be installed inside the
ABB string inverter's wiring box.
c. Before installing the 24Vdc power supply, open (turn OFF) the PV system AC disconnect switch AND the PV breaker
to ensure the inverter is disconnected from the grid and from the PV modules.
d. Follow the instructions starting in section 7 to install the 24Vdc power supply. Note that the power supply pigtail coming
out of the RSD box (FIgure 5) will house both the 24V and return wires.
e. The new UNO-DM+ inverter will already have a 24Vdc power supply inside the inverter wiring box and you can skip
sections 7 & 8. Only the older PVI-3.0/3.6/ 3.8/4.2/5000/6000-TL inverters and the UNO 7.6/8.6 inverters will require
you to add the 24Vdc power supply as described in sections 7 & 8.
Note that an uncovered terminal blocks' interior metal will carry the AC voltage. Therefore, the terminal block
cover is required to ensure there is no exposed AC voltage.

9. Connecting the control wires between RSD(s) and power supply
Step 6: The installer may connect the 24Vdc supply cable (F) to a UL approved “I” or “T” splice connector depending on the number
of SRD boxes or into a UL approved junction box on the roof. Installer is allowed to clip off connectors in order to use the junction box.
Run the 24Vdc wire pair from the splice connector or junction box to the inverter and attach to the 24Vdc power supply. (Note the
power supply terminals accept wire sizes 18 AWG to 16 AWG). Connect the conductors as follows:
Strip 0.3" of insulation from the ends of the wires.
Use a small Philips screwdriver to attach wires to the (+) and (-) outputs of the power supply. Torque all power supply terminal screws
between 4.43 lb.-in (0.5 N•m) and 5.31 lb.-in (0.6 N•m).
The 24Vdc power supply conductors may be routed through the DC conduits to the location where the RSD device is installed near
the PV array or the installer may run these conductors through a separate DC conduit.
Note: 1. The power supply installed in the inverter wiring box is a Class 2 power source. Class 2 circuits are permitted to be reclassified
as Class 1 circuits per NEC 725.130 (A) exception 2. By reclassifying this circuit at Class 1, the 24Vdc conductors may be installed
in the same raceway as the PV conductors as specified in section 725.48(B) (1) of the NEC. Be sure to follow all Class 1 wiring
methods as stated in section 725.49 to ensure compliance. The installer should mark out any reference to 'Class 2.'
2. Placing the 24Vdc power supply conductors in the same EMT conduit as the PV conductors will require use of 18AWG 600Vdc wire.

6. Once the inverter is connected to the grid and producing power, remove the grid voltage from the inverter by opening AC
circuit breaker or circuit disconnect and monitor the inverter DC input voltage.
7. Confirm the inverter DC input voltage is below 30Vdc within 30 seconds of grid disconnect by measuring the voltage across
the DC input terminals inside the wiring box.
Testing the PV System only, without Rapidshutdown or to Perform Anti-Islanding Test:
If it is necessary to test the PV system without the rapid shutdown being operational, bypass the rooftop RSD by directly
connecting the PV strings to the corresponding PV array output conductors.
Prior to commissioning the PV system, the PV strings and PV output circuits must be properly reconnected through the RSD,
and the system must be tested as described above.
Testing Rapid Shutdown within the PV system:
Once the PV system has been installed, test the RSD system. The intention of the test is to confirm inverter DC input drops
to less than 30 Vdc in less than 30 seconds after AC is removed. A multimeter will be required to measure the DC voltage.
PPE must be used in all steps while working with this equipment.
1. Before connecting the inverter to the grid, measure the output resistance of the RSD at the inverter input terminals (see
Table 4 for correct values.)
12. System testing - required before system commissioning
The inputs of both rapid shutdown boxes
are rated for 25A which allows for single
or paralleled string to be connected to
one input. On a 2 rooftop system either
version of the Rapid Shutdown box, or
both, may be used.
7c. Installing the power supply
Step 3: Snap the orange cover on one terminal block from the kit, prior to mounting it on the DIN rail. Install both terminal
blocks from the kit on the DIN rail to the right of the power supply. The terminal cover must be on the right-side end. Push
the two new terminal blocks, the terminal cover, terminal block 3 and end caps to the left, up against the 24V power supply.
Figures 10 and 11 show the two new terminal blocks in place.
7d. Installing the power supply
Step 4: Replace the inverter AC conductors in the top positions of the two, new left-hand terminal blocks by inserting a ¼”
flat screwdriver into the square holes. Insert the wire labeled '1' into terminal 1 and wire labeled '2' into terminal 2. The wires
are shown in Figures 12 and 13. Be sure the wires are completely seated. Give each wire a pull test to confirm the wire is
snugly held in place.
11. Operation of the RSD
Note: To comply with NEC 690.12 rapid shutdown requirements, within the ten-foot perimeter of the PV array, DC voltage
must be reduced to no more than 30Vdc, and power to <240VA, within 30 seconds. The RSD system is activated through a
loss of AC voltage to the inverter. When the loss of AC occurs, the RSD power supply shuts off. This results in opening the
relay contacts of the RSD device and de-energize the system per NEC 690.12 requirements.

Wiring box for UNO-7.6/8.6
Figure 12 Figure 13
10. Multiple-RSD installation
Each 24Vdc power supply has terminals for connecting four RS1-1PN6-MC4 devices or two RS2-2PN6-MC4 devices. Repeat
the wiring directions above to connect a second RSD control circuit to the second output positions on the power supply.
However, each 24Vdc power supply in the kit can power up to six single-output RSDs (ABB P/N: RS1-1PN6-MC4) or three
dual-input RSDs (ABB P/N: RS2-2PN6-MC4). For more than two RSDs, you must use an UL approved "I" or "T" splice or a
UL approved junction box, or equivalent.
Without the approved splices an additional power supply would be required to power more than two RSDs in a single-inverter
system. UNO-7.6/8.6 inverters have sufficient space for additional power supplies. If using PVI-series ABB in-verter, there may
be space for only one power supply on the inverter DIN rail.
7a. Installing the power supply
Step 1: Open the inverter wiring box. Disconnect the inverter output conductors from top-side of terminals 1 and 2 by inserting
a ¼” flat screwdriver into the square holes. (The square holes are indicated in Figures 6 and 7.) Lightly press the screwdriver
toward the wire slot until the clamp opens.
7b. Installing the power supply
Step 2: Push the end caps on the DIN rail to the right. Pop the terminal block 1, 2 and GND off the DIN rail by pulling upwards
from the bottom. Install the 24V power supply on the DIN rail, by using a small screwdriver to pull down on the tab on the
bottom of the power supply. See Figures 8a-8d and 9.

Note: Once the Grid Connections are done to the power supply, measure the output voltage of the power supply to be 24V. If
not, adjust the screw off the power supply until it reads 24V.
8. Wiring the Power Supply inputs from the Grid
Step 5: Connect the ground (green) wire from the kit to the ground terminal of the power supply and to the green terminal block.
Connect one black wire between the center position of the first terminal block and terminal "L" on the power supply. Connect
the 2nd black wire between the center position of the 2nd DIN rail terminal block and terminal "N" on the power supply. Confirm
all wires are completely seated. Torque all power supply screws to 4.43 in-lb (0.5 N.m) - 5.31 in-lb (0.6 N.m). Figures 14 and
15 show the two terminal blocks in place and correctly wired. Give all wires a pull test to confirm the connections are solid.

PVI-3.0/3.6/3.8/4.2/5000/6000-TL UNO-7.6/8.6
Do NOT energize the system until proper resistance values are
measured.
2. Connect a voltmeter to the inverter DC input voltage at a
convenient location.
3. Reinstall the inverter switchbox cover.
4. Connect the system to the grid by closing a circuit breaker or
circuit disconnect.
5. Begin monitoring the DC input voltage at the input terminals.
Ensure that the proper input voltage is present based on the
PV plant design documentation.
A system with two or more RSD boxes
will require either a UL approved "T"
connector (available from ABB) or a UL
approved junction box.
