2. Improvement on the power connector of the micro-BTS. As the output of UPS
is screwed with the bolt, the power supply of the current micro-BTS cannot be
plugged. To improve this situation, a connector board may be used. Cut off the
input 3-core connector on the connector board, divide by L-N-PE and connect
respectively to the L-N-PE of the UPS’ output end. Be careful not to make any
mistakes in this operation. In most cases, the brown line is for the live line (L),
the blue line for neutral line (N) and the yellow-green line for protection
grounding line (PE).
3. At present, the UPS employs the 232 communication mode and its RS232
interface differs from other standards. There are six pins in total — Pin 6: RXD
(blue); Pin 7: GND (green); Pin 9: TXD (black), useful signal. The backup 232
interface of the BDM board is defined as: Pin 2: RXD; Pin 3: TXD; Pin 4:
GND. Therefore, the 232 connector of UPS has to be changed, that is: Connect
RXD (blue) to Pin 3 of DB9, TXD (black) to Pin 2 of DB9, and GND (green)
to Pin 4 of DB9. Remember that the DB9 connector must be a “male” one.
4. Precautions for installation
1) Good ventilation for heat dissipation;
2) Keep from the place with corrosive gas;
3) The top of UPS must not be occupied by any objects, nor could it be taken by a
sitting person, lest the air vent might be blocked;.
