Table 2-3 Power conditions
Rated voltage: 110/220 VAC with voltage fluctuation ranging from 100
VAC to 240 VAC.
Rated voltage: -48 VDC with voltage fluctuation ranging from -38 VDC
to -57.6 VDC
A backup UPS is preferred to keep the ISCOM6820-GP running in case
of power failure.
2.2.3 Grounding conditions
The ISCOM6820-GP adopts common earthing mode with the ground resistance not greater
than 1 Ω. Good grounding is the primary guarantee for lightning protection and anti-
interference.
2.2.4 Other conditions
Before installation, check whether the supporting equipment is ready. For example, check
whether the optical networking equipment is installed well, the fiber is laid in place, and cable
