About this document 19P0911588 Issue 01 Enterprise Edge 2.0 Programming Operations GuideSafety information for European customersThe CE mark indicates that the Enterprise Edge equipment meets the requirementsof the following EU Directives:• Low Voltage Directive (73/23IIC)• Electromagnetic Directive (89/336/EEC)WARNINGThe instructions in this manual are intended to beperformed by Qualified Service Personnel.Risk of shock.Ensure the computer is unplugged from the powersocket and that any telephone or network cables areunplugged before opening the computer.Read and follow installation instructions carefully.Only qualified persons should service the system.The installation and service of this hardware is to beperformed only by service personnel havingappropriate training and experience necessary to beaware of hazards to which they are exposed inperforming a task and of measures to minimize thedanger to themselves or other persons.Electrical shock hazards from the telecommunicationnetwork and AC mains are possible with thisequipment. To minimize risk to service personneland users, the Enterprise Edge system must beconnected to an outlet with a third-wire Earth.Service personnel must be alert to the possibility ofhigh leakage currents becoming available on metalsystem surfaces during power line fault events nearnetwork lines. These leakage currents normallysafely flow to Protective Earth via the power cord.Therefore, it is mandatory that connection to anearthed outlet is performed first and removed lastwhen cabling to the unit. Specifically, operationsrequiring the unit to be powered down must have thenetwork connections (exchange lines) removed first.
