IQ system Controller 2 Installation

J ) RSD Aux contact wiring when System Controller 2 is used with
non-IQ8 micros
IQ System Controller 2’s RSD functionality only applies to IQ8 PV mi-
cros connected to the PV lugs/port. The RSD switch will NOT work for
IQ6/7 or M215/25 micros connected to PV lugs/port or the panel
directly.
When using the System Controller 2 with the IQ6/7 or any other micro
inverters apart from the IQ8 Micro inverters, the Rapid Shutdown initia-
tor should not be wired to the aux contacts of the IQ System Controller
2.
In those situations, the Rapid Shutdown aux contacts need to be by-
passed and a seperate rapid shut initiator needs to be wired.
The method for bypassing the Rapid Shutdown aux contacts of System
Controller are as below:
1. Connect the cable header assembly in the auxiliary contacts of NC3
and NC4
2. Use a 12 AWG wire in order to connect the 2 contacts of NC3 and 2
contacts of NC4 as shown in the diagram below.
In order to wire a rapid shut down initiator to System Controller 2
when using a non-IQ8 micro inverter one of the following steps can be
followed
1. The AC circuit breaker installed within the IQ-Combiner.
2. The AC circuit breaker installed within IQ System Controller
3. A dedicated AC disconnect switch located in series with the com
bined PV inverter circuit
When using a non-IQ8 microinverter both the bypass of RSD aux con-
tacts and one of the above RSD wiring needs to be done.
