EN
In addition to the information provided in this Quick Installation Guide
(QIG), the safety and installation guidelines provided in the technical
manual must be read and followed. The technical documentation for
the product is available at www.abb.com/solarinverters.
3. RSD installation location
a. The RSD box is intended for roof installation within ten feet of the PV array.
b. Install the RSD box on the photovoltaic racking system.
c. The RSD box may be installed at angles from horizontal to vertical.
d. Ensure there is sufficient working area around the RSD box to allow easy access for maintenance and/or
servicing of the PV system. If installing RSD under a module, place it under the first or last module in a row
in order to allow for easier access. Never install the RSD in such a location that would require the removal of
multiple modules in order to gain access.
e. In the RSD product manual located at www.abb.com/solarinverters, reference the Technical Data section to
check the environmental parameters to be observed (degree of protection, temperature, etc.).
f. Maximum operational ambient air temperature must be considered when choosing location. Exposure to direct
sunlight is permitted; however, installation under a module is preferred.
4. Mounting the RSD box
a. The mounting bracket (A) will come attached to the RSD box. The bracket contains six screw holes (B). The
RSD box may be raised or lowered to match four bracket screw holes as needed for clearance from modules
or roof. In case the bracket needs to be adjusted, reattach the bracket to the RSD box with the four provided
.
screws and torque to 3.5 N
m (2.6 ft-lb).
b. When mounting the RSD to the PV module racking system, use the racking manufacturer's components to
secure the mounting bracket (A) to the racking structure through the holes (C) provided on the bracket. Only
one mounting point is required (center). When using more than one mounting point, choose any of the three (C)
provided. The racking manufacturer's supplied bolt is to be torqued to 23 N·m (17 ft-lb).

NOTE –
This RSD device is for use with ABB single-phase inverters only. The device has been tested and certified
for use only with these inverters. Use of the RSD with any other inverter may not perform as specified and therefore not
comply with Rapid Shutdown requirements. Use of the RSD with other inverters will void the warranty of this product.
ELECTRICAL WARNINGS –
The ABB RSD system is designed to comply with the 2014 NFPA 70 National Electric Code, section 690.12 and
—
is tested according to international safety requirements (UL1741); however, certain safety precautions must be
observed when installing and operating this product. Personal protective equipment (PPE) must be worn at all
times when servicing this equipment.
Wiring methods used should be in accordance with the National Electric Code, ANSI/NFPA 70 and/or any
—
prevailing local codes and regulations.
For suitable wire size (AWG), refer to National Electrical Code, Table 310.15(B)(16) for U.S. applications. Use

5. Wiring the RSD box
a. Ensure power is not present on the conductors to be connected, wear appropriate PPE, and use insulated tools
when working with this equipment.
b. The equipment grounding conductor (EGC) must connect the inverter and array in order for the inverter's
ground fault protection to operate as required. Ensure the EGC from the array continues on to the inverter. The
RSD enclosure is polycarbonate and does not require bonding. Refer to local codes for appropriate wire size
on all conductors.
c. The inputs and outputs must be connected to the RSD by the mating pair of the provided Amphenol connector.
Follow the instructions included with the Amphenol crimping tool (not included - part number CTL-161801) to
properly crimp connectors on the PV conductors.
d. The power conductors must be connected to the RSD by the Amphenol power connector. Follow the instructions
included with the Amphenol crimping tool (not included - part number CTL-161801) to properly crimp connectors
onto the control power conductors.
6a. Wiring the power supply
a. The RSD kit includes two terminal blocks, a 24V power supply and three short conductors used to connect the
power supply to the inverter AC terminals and ground. This power supply is to be installed inside the wiring box
of the ABB string inverter.
b. Before installing the power supply, open the PV system AC disconnect switch or PV breaker to ensure the
inverter is disconnected from the grid.
c. The RSD Power Supply must only be connected to a three-wire 240V line-to-line or two-wire 208V line-to-line
inverter output.
The RSD kit is NOT compatible with a 277V grid connection. It must only be used with a 208V or 240V
grid connection.
C
Replace the inverter's AC terminals with the terminals provided in the RSD kit. These new terminals are three-position
terminals which will allow the power supply to be connected to the inverter's AC output.
Included in the RSD kit is a terminal block cover which must be installed on the exposed side of the
three-position terminal blocks supplied with the kit. In Figure 1 below, the contacts of the green-colored
ground terminal block and beige-colored line terminal block would have direct metal-to-metal contact
on the DIN rail without the terminal block cover. Figure 2 shows the terminal block cover installed on
the line terminal block which prevents this direct metal contact. The terminal block cover is required
to ensure there is no metal contact between the terminal blocks.
