Output Connection (Ac) - ABB REACT 2 Quick Installation Manual

10. Output connection (AC) (continuation)
• Install the single wires (phase, neutral and ground) on the head
of the connector respecting the indications printed on each of
the three connection terminals (tightening torque 0.8...1Nm)

• Connection for the AC output connector to the inverter:
For all inverter models, connection to
the electrical grid is carried out using
the AC output connector
1. Remove the pre-installed protective cover on the
inverter by pressing on the the latch with a flat
screwdriver.
2. Insert the counterpart in the AC output (GRID)

connector being careful to align the referen-
ce points (present on both connectors) which
prevent connection errors.
3. Push the counterpart until you hear "click"
4. Give a pull test to confirm the connection is
secure.
In addition, the connector must not be subject to tensile forces (examples: do not connect weights to the AC cable, do not leave
excess cable windings hanging, etc).
In order to maintain the inverter's level of IP protection, the corresponding part must be installed with the AC cable connected or
the protective cover, on the AC output connector.
• Installation of the external protective grounding cable:
In addition to the grounding protection previously connected to the AC output connector
- install a second protective grounding cable to the dedicated connection point on the metal frame (lower part) of the REACT2-UNO.
- install a jumper between the protective grounding connection points on REACT2-UNO and REACT2-BATT
To execute all external grounding connection, follow the procedure described below:
1. Make a jumper earth cable using the two cable lugs supplied (minimum cross-section not less than 4mm²). The cable must be long enough to connect
the REACT2-UNO external protective earth
2. From among the components supplied, find the M5 nut, M5 flat washer and M5 serrated lock washer.
3. Install the earth cables following the below installation sequence
Installation sequence:
knurled washers
external protective earth cable
jumper earth cable
flat washer
M5 nut (torque of 4.1 Nm)
4. Connection on REACT2-BATT external protective earth [A]
Follow the below installation sequence
