B.3. Installation
Take the following steps to minimize EMI when wiring:
1. Make sure the input and output cables and the battery cables are kept separate from each other to avoid
unnecessary noise interference.
2. Keep the path of the communication cables (RJ45, RS232, RS485, USB, EPO and Shutdown) separate from
the I/O and battery cables. If unavoidable, place them at 90 degrees to each other and at least 20cm apart.
Figure 2 Cabling
3. The UPS is equipped with an EMI filter. To prevent potential current leakage hazard, ensure that the AC main
supply is securely grounded.
B.4. Start-up Procedure
1. Position the units as shown in Figure 1.
2. Use communication cables that are less than 7M long, connected as a “Ring” loop.
