Grounding instructions

The grounding conductor wires must be 16-gauge or larger, and either bare or covered with green
or green-and-yellow jacket. Conductors and power receptacles must connect to earth ground at the
service equipment (usually a cold-water pipe or copper ground rod). The grounding screw can be
connected to either the side or the back of the IP PBX, depending on whether it is rack-mounted or
wall-mounted. The supplemental ground must:
• Be used regardless of power cord ground.
• Be connected to the grounding screw on the IP 40 or IP 200.
• Retain ground connection when the IP PBX's external power supply is unplugged.
Note: IP PBXs' lines are protected against a 10KV surge only if the earth ground procedures de-
scribed above are followed.
Power
IP PBXs
Each IP PBX requires a 110VAC outlet. Use only the 24VAC 3.0A Class 2 power supply module
provided. A clean, isolated power source in conjunction with a UPS is required. A fully loaded
IP 200 draws no more than 50 watts.
If AC power is interrupted, the system will drop all connections. When power is restored, the
system will resume normal operations in about five minutes, having retained full programming and
clock setting.
UPS
For system protection and to maintain uninterrupted operation, an uninterruptible power supply
(UPS) is required. A UPS rated for 200 VA will provide approximately two hours of uninterrupted
service for a fully loaded IP 200. Every 50 VA of capacity added to the UPS will yield about a half-
hour of additional uptime.
MOH port
The MOH port (message-on-hold or music-on-hold) connector on the lower right-hand side of the IP
1
PBX front panel is a standard / " monophonic mini-jack, used for loading custom MOH recordings or
8
for playing live music-on-hold from an external source such as a radio or CD player.
