4.2 Controller Assembly
The controller assembly controls the fan. A multi-function relay is placed on the controller assembly.
The multi-function relay is for switching on and off a fault indicator or another external load based on
parameters and measured values of the inverter (for further information regarding the use of the
multi-function relay, see the Technical Description "Multi-Function Relay and OptiTrac Global Peak"
and installation manual of the inverter available at www.SMA-Solar.com).

5.2 Removing the Multi-Function Relay
If a multi-function relay is pre-installed, the installation area of the controller assembly is blocked.
Befo re install ing the fan retrofit k it, the multi -function relay must be removed according to the following
procedure.
1. Disconnect the inverter from voltage sources and open it (see inverter installation manual).
2. If the multi-function relay is assigned, disconnect the supply voltage to the multi-function relay
and ensure that the device cannot be reconnected.

5. If the terminals are assigned, remove the connection cable from the inverter:
• Flip up the terminals and pull out the insulated
wire. Hint: Note down the order of the
connected insulated wires. The connection to
the multi-function relay on the controller
assembly will be easier this way.
• Remove the connection cable from the inverter through the cable gland. To do this, slightly
loosen the swivel nut.
6. Loosen the screw on the pre-installed multi-function
relay using an Allen key AF 3.
7. Remove the multi-function relay from the inverter.

5.3 Installing the Fan Retrofit Kit in the Inverter
Requirements:
☐ The inverter must be disconnected from the power supply and the lower enclosure lid must be
opened (see inverter installation manual).
☐ The mul ti- fun cti on r ela y mu st b e re mov ed a nd t he dis pla y fl ipp ed up (see Section5.2 "Removing
the Multifunction Relay", page12).
1. Place the controller assembly in the inverter and
push the ribbon cable upwards behind the display.
The key of the controller assembly must fit into the
cut-out of the display retainer.
2. Fasten the screw of the controller assembly with an
Allen key AF 3.
3. Remove the cover of the enclosure opening for fan enclosures.
4. Insert the fan with fan enclosure in the enclosure
opening. The arrow on the fan enclosure must face
the display.
5. Route the locking tabs on the right-hand side of the fan enclosure underneath the enclosure wall
and press the fan with fan enclosure in the enclosure opening.
