Chapter 13 Hardware Installation Check
13-5
15. The lifting lug of a power cable should be soldered or pressed firm and upright.
16. The power cable and copper lug must be contacted in a reliable and firm way
and are sealed with an adhesive tape. The copper lug must be connected firmly
with the power cabinet (or the BTS rack).
17. Insulated protective sleeves are well installed on both connecting terminals of
the power supply on the rack top.
18. Power cables, ground wires, trunk lines and RF cables should not be broken or
damaged.
19. The cable labels on both terminals of power cables and ground wires should be
clear and correct.
20. The bare wires at the connecting terminals and lug handle should be tightly
wrapped with insulating tape or put in a heat-shrink tube instead of being
exposed to outside.
21 The connecting terminals should be equipped with flat washers and spring
washers.
13.5 Check of T1 Cable Installation
The installation check of T1 cables involves the following:
1. T1 cable connectors are reliably installed, without any short-circuit or damage.
2. T1 cables are connected correctly and labeled clearly.
3. No T1 connector gets loose. Test with a multimeter whether the connector shell
and ground wire system are well connected. Otherwise, it shows that the ring
flange of the connector and shell are in poor contact.
4. The T1 cables on the set top should reserve some margin length. Do not stress
them in case they cannot be reliably connected with the rack connectors when
the cabling rack vibrates.
5. T1 cable connectors must be connected reliably.
