2.
Rest the left-hand side of the interface card on the control PCB’s A-port mounting support. Align
the positioning notch on the interface card with the A-port positioning key, and then slide the
interface card to the left to engage the key into the notch. Refer to step
c
in Figure 6.
3.
Rotate the right-hand side of the interface card downward to engage connector CN1 (on the back
of the interface card) into the A-port connector (CN4) on the inverter’s control PCB. Ensure that
the connectors are fully engaged. Refer to step
d
in Figure 6.
To ensure that the interface card is fully aligned and seated into the communication
port, be sure to perform steps
c
and
d
in the proper order. Failure to do so may
lead to insufficient connector insertion and result in contact failure.

4.
Install the two M3 x 6mm screws included with the kit into the standoff mounting holes located at
the upper-left and lower-right hand corners of the interface card. Tighten the screws to secure the
interface card to the control board PCB. Refer to Figure 7.

5.
Connect the network cables as necessary. Insert the Ethernet cables into the Ethernet jacks,
making sure that they are fully seated. Ensure that the cables are routed in such a way that they
will not be pinched and are not located near any power-carrying wiring, such as the inverter’s input
power or motor wires.
6.
Reinstall all covers removed in step 1. Take a moment to confirm that the Ethernet cables are not
being pinched and are not routed near any power-carrying wiring.
For reinstallation instructions, refer to the FRENIC-MEGA Instruction Manual, Chapter 2,
Section 2.3. The keypad enclosure must also be closed on 30kW and larger inverters.
