3.3.2 Cable Entry Design
For easier onsite cable connection, all cables between the internal devices have been
connected before delivery.
All cables between the MV Station and the external are routed through the bottom of the MV
Station. All cables coming into or out of the MV Station should be protected properly, for
example, use cable pipe to prevent damage by rodents. After cable connection, all cable
entries should be sealed by fireproof mud or other appropriate materials.
The MV Station bottom cable entries are shown below.
Function of each opening is shown below:
