1 Safety Instructions

1.1 Electrical

• To avoid damaging the Bizfon server or associated system components, be sure the voltage switch on the

rear of the unit is set to the appropriate setting for your location. The unit is shipped in the United States

with the switch set to 115 VAC.

• Before working inside the Bizfon server, unplug the unit to help prevent electrical shock or system damage.

• To help prevent electrical shock, the permanent ground connecting screw located next to the power

receptacle on the rear panel must be permanently connected to earth using 18 AWG wire or larger. The

power cable is also equipped with a three-pronged plug to help ensure proper grounding. Do not use

adapter plugs or remove the grounding prong from the cable. If an extension cord is required, use a three-

wire cable with properly grounded plugs.

• To reduce the risk of fire, use only 26 AWG or larger UL listed or CSA certified telecommunications line

cord.

• To help protect the Bizfon system from sudden, transient increases and decreases in voltage, use a surge

suppressor, line conditioner, or uninterruptible power supply (UPS).

• Be sure nothing rests on or interferes with the system’s power cables.

• Make sure the cables are not located where they can be stepped on or tripped over.

• Do not spill food or liquids on the Bizfon server.

• Do not push any objects into the openings of the server. Doing so can damage the unit or cause electrical

shock.

• Keep the Bizfon server away from heat sources such as radiators.

• Do not block the cooling fan opening on the rear panel.

1.2 Electrostatic Discharge

Static electricity can harm the components inside the Bizfon server. To prevent static damage, discharge

electricity from your body before you touch any of the unit’s electronic components. You can do this by

touching an unpainted metal surface on the unit’s chassis, such as the rear panel.

As you continue to work inside the unit, periodically touch an unpainted metal surface to remove any static

charge your body may have accumulated.

You can also take the following precautions to prevent damage from electrostatic discharge:

• When unpacking a static-sensitive component, do not remove the component from its anti-static packing

material until you are ready to install the component. Be sure to discharge static electricity from your body

just before you unwrap the component.

• When transporting a static-sensitive component, first place it in an anti-static container or packaging.

• Handle all sensitive components in a static-safe area. If possible, use anti-static floor pads, straps, and

workbench pads.
