Caution:
To reduce the risk of fire, use 26 AWG or larger telecommunication
line wire for the power supply connection.
The Power Supply Unit (iPSU) supplies power to the i3812V and is installed by your service provider. The
iPSU optimum operating temperature is between –5
i3812V, the iPSU must be installed in a sheltered area — either inside the garage or home. If the iPSU is
equipped with a backup battery, during a temporary AC power outage, the power source is switched to the
battery without interruption of the voice-over-IP service. When the AC power is restored, the power source is
switched back to the AC power supply. The switchover between the AC power supply and the battery is
automatic and instantaneous.
The iPSU itself requires no regular maintenance; however, the battery inside the iPSU requires periodic
replacement. Refer to the
battery.
Figure 2
shows the location of the two indicators and two buttons on the power supply unit;
Table 2
lists and describes their functions.
