The total capacity of the high-frequency switching rectifier must satisfy the
power of the communication loading and battery charging. If there are 10 or
fewer active rectifier modules, configure one backup module. If there are
more than 10 active modules, configure one backup module for every 10
active modules.
Install storage batteries in two or more groups. The capacity is determined by
the duration for which the storage batteries must supply power. For most
offices, the batteries should be able to supply power for at least one hour.
If the cable jacket or insulation is visibly dirty, clean it before assembly.
If the jacket or insulation of a cable has visible damage, irreparable scuffing,
or other defects, do not use the cable.
If the shield layer of a cable is damaged, do not use the cable.
If the cable jacket or insulation cracks after the cable is bent or twisted,
discard this cable and check whether other cables have the same problem. If
other cables have the same problem, replace these cables.
Do not use connectors with visible defects, damage, rust, or scuffing.
Do not use connectors if their shells or pins have exposed part or uneven
plating, or their pins are lost, broken, or bent.
Do not use connectors that have dirt on their pins or in their jacks or if there
are conductors between pins or between pins and the shell.
Use dedicated tools or tools delivered by Huawei and follow the methods
given here during assembly.
Hold terminals of cables instead of pulling the cables themselves when
installing or removing cable components.
Take the following precautions when cutting or stripping cables:
–
Make cables slightly longer than necessary.
–
Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the
coils using bundling ropes. The inner diameters of the coils should be
larger than 20 times the outer diameters of the cables.
–
When stripping the jackets of cables, avoid damaging the shield layers
(braid or aluminum foil), insulation, core conductors, and other jackets
that do not need to be stripped.
–
After assembling cables, cut all visible cross sections of jackets to ensure
that the cross sections are arranged neatly.
