The three Power Supply Units are mounted in the vicinity of the Transceiver Unit. The physical distance is limited by the length of the power cables between the units.
The power supplies are controlled from the Processor Unit. The connection is made using three Ethernet cables from the Ethernet switch in the Transceiver Unit.
The following output voltages are provided by the three power supply modules in each Power Supply Unit:
|
• |
+12 VDC (approximately) |
|
• |
+75 VDC (approximately) |
The power supplies inside each Power Supply Unit will be very warm during normal operation.
WARNINGThe Power Supply Unit contains high voltages. Unless required for maintenance purposes, do not open the cabinet door while the ME70 system is switched on.
Dedicated power cables connect the Power Supply Units to the Transceiver Unit. The cables are included in the ME70 delivery, and they have been connected to the terminal blocks in the Power Supply Units. The cables must be run in steel conduits.
NoteThe power cables cannot be spliced. If the cables are too long, cut them to a suitable length. If you wish to keep long cables, do not coil them.
