4-6-1 Preparations

1. The UPS should only be installed by a qualified electrically employed person
2. De-energize all input (AC or DC) or output power of the UPS before installing
cables
or making any electrical connection.
3. Ensure that all cables are correctly marked according to the purpose, as well as
the
polarity, phase and diameter.
4. If the input/output power of the UPS is WYE-WYE (Y connection), "Neutral"
and "Ground" should not be connected.
If the input power has V
before UPS and input power source. Then, connect "Neutral" and "Ground" of
the UPS together.
5. Make use of suitable conduits and gland to protect I/O wiring according to local
regulations. Refer to Table 4-3.
6. If after the installation many cables are ducted very close together it is
recommended to use cables with isolations made for higher temperature ranges.
