This section details the requirements for safe installation and operation of the Sonus SBC 1000/2000 system. Be sure to review this information before placing the system into operation.

1. Restricted Access - The product is for use in a Restricted Access Location only.

2. Grounding the Sonus SBC 2000 equipment - The equipment has provision for a permanently connected protective earthing conductor. Attach a 14 AWG copper wire and a 1-hole UL approved lug to the grounding connection. Use Panduit PN14-6R or equivalent.

3. Rack Mount Instructions
(a) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature specified by the manufacturer.
(b) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
(c) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
(d) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
(e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g., use of power strips).

4. CAUTION - Notes for Replaceable batteries and Telephone line cord.
(a) Replaceable Batteries - CAUTION: Risk of Explosion if Battery is replaced by an Incorrect Type. Dispose of Used Batteries According to the Instructions.
(b) Telephone Line Cord - CAUTION: To reduce the risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL Listed or CSA Certified Telecommunication Line Cord.

5.Nordic Country Notice
(a) For Finland: "Laite on liitettävä suojamaadoitus¬koskettimilla varustettuun pistorasiaan"
    For Norway: "Apparatet må tilkoples jordet stikkontakt"
    For Sweden: "Apparaten skall anslutas till jordat uttag"
(b) The equipment must be installed only in a Restricted Access Location.
(c) The systems installed in Sweden, Finland and Norway must have supplementary grounding terminal at the chassis frame for the permanent connection of grounding conductor described in System Grounding Requirements.
