In accordance with National Electrical Codes (NEC), please install the suitable
conduits and cable sleeves.
3 When connecting the input/ output power cords, please observe the following rules.
• Turn off the UPS and cut off both AC source and the battery source before
connection.
• Calculate the power consumption of the loads to avoid an overload condition.
•
Ensure that the screws are tightly fixed after connection. Please refer to
Table 7-1
.
4 Backfeed Protection:
When the UPS runs in battery mode or during AC power failure, the UPS’s inner
voltage or energy might be fed back to the input terminals, either directly or via
a leakage loop. To avoid the risk of electric shock resulting from the backfeed,
installing of a backfeed protection device between the AC input and the UPS is
highly recommended.
The UPS doesn’t have any built-in backfeed protection device. Installation
of the backfeed protection device between the AC input and the UPS is
highly recommended.
If there is no backfeed protection device installed between the AC input
and the UPS, please:
1) attach a warning label on the switch or breaker that controls the AC power
supply to the UPS,
2) check if any hazardous voltage exists on any terminals connected to the AC
power. The warning label shall carry the following wording or equivalent.
Before Working on This Circuit
-Isolate Uninterruptible Power System (UPS)
-Then check for Hazardous Voltage between all terminals
including the protective earth.
