2. Connect the male Molex connector with the female Molex connector and ensure that the positive latch on
the connectors is achieved. Refer to Figure 3. Position the connection in such a way that the wires will not
be compromised by securing the extension arm to the balance arm.
4. Line up the holes on the bottom of the extension arm with the holes on the arm joint at the balance arm.
5. Use the provided stainless steel thumb screws (3 X 8-32 X ½”) to secure the connection. If needed, use a
wrench to tighten the screws.

4.2.4 ELECTRICAL CONNECTIONS
Option 1 – Installing the transformer box outside MRI room using RF filter
The transformer box is equipped with 30ft of cord on the secondary side and 10ft of cord on the primary
side. If installing the transformer box outside the MRI room, connectors may be required on the secondary
side to accommodate the use of an RF filter. RF filter connectors will be different based on which RF filter is
used. Total length of cord on the secondary side should not be altered from the original 30ft. If your facility
construction requires alterations beyond these guidelines, please contact Sunnex Technical Support.
