Equipment Installation
Removal of Overhead Lifting
Brackets and Channels Before joining to adjacent equipment, the lifting brackets and exterior vertical
lifting channels from the converter cabinet must be removed.
Removing of the lifting brackets requires access to the interior of the enclosure
where corresponding internal brackets are located and require removal. Please
refer to
page 16 for hardware removal details.
It will be necessary to remove the converter roll-out modules from the enclosure
to install power connections to the adjacent equipment and to install hardware to
secure the enclosure to its floor.
To remove converter modules from the cabinet, the following operations are
necessary:
1. Open the Medium Voltage Doors (see below)
2. Remove the Medium Voltage Front Cover (
page 10 )
3. Disconnect Fiber Optic Cables (

4. Disconnect Flexible Braided Links (

Opening the Front Medium
Voltage Doors of the
Converter Cabinet Access to the medium voltage converter section is attained by opening the three
lower doors. The left door is generally equipped with interlocking with upstream
equipment. The specifics of this interlocking depends on customer requirements
and is provided in the customer drawings.
Rotating the door handle unlatches the door allowing it to be opened. DO NOT
force open the doors.
The middle and right medium voltage doors are mechanically interlocked with
the left medium voltage door such that the left door must be opened before the
middle and right doors can be opened. Similarly, the left door cannot be closed
until both the middle and right doors are closed and latched.
