Observe the general safety precautions against personal injury and equipment damage outlined in the regional Installation Safety Manual at all times.
• Rules concerning the premises (site or building safety panels).
• Statutory country regulations.
3.2 PreparationsPrior to starting the operations presented in this method, arrange all materials, tools, and test equipment at the work location so as to minimize fatigue and inconvenience.
4.1 OverviewThe product has been designed to meet international Product Safety requirements. As part of the requirements, the instructions in this document must be respected to ensure the Safety of people, equipment and property. A Product Safety Engineer must validate any deviations from the Product Safety requirements, to ensure continued compliance, prior to implementation. Failure to comply with these requirements may result in risk to people, equipment and property.
Procedures listed in Core I&C documents must be performed by a qualified electrician. The Safety procedures outlined in this document are recommended guidelines. All national and local codes must be respected.
4.2 Requirements for Product SafetyThe BSC e3 & TCU e3 installations must respect the following Product Safety requirements.
4.2.1 General Information
Products intended for the United States and Canada have been approved to UL1950 and CAN/ CSA C22.2 No 950 (Safety of information technology equipment, including electrical business equipment). All installations must conform to the requirements of the National Electrical Code (NEC) and the Canadian Electrical Code (CEC).
Products intended for the European Community, have been approved to EN60950 (Safety of information technology equipment). For other countries, products have been approved to IEC 60950 (Safety of information technology equipment). All installations must conform to the requirements of IEC364 (Electrical Installations of Buildings). Note that country specific deviations of this document may exist.
For Product Safety considerations, the product is considered to be:
1. The product must be secured/mounted according to the requirements of document GSM BSC e3 & TCU e3 Site Specifications (0000003-06-9475). Refer to this document for requirements such as mounting fasteners, mounting hardware, equipment spacing, mounting surface types, lifting of product, etc.
2. All connectors and cables which are exposed must be suitable for the intended use. Conduit may serve to protect wires from mechanical hazards.
3. The customer or the agent of the customer must supply power feeders, which meet national requirements. The current, voltage, and temperature specifications of the cable must comply with national requirements.
4. The product should be installed in a restricted access room. The access should be restricted to qualified service personnel.
5. The product can be installed in seismic areas up to Zone 4. It corresponds to the highest risk areas, according to [R6].
4.2.3 Electrical
1. Refer to document GSM BSC e3 & TCU e3 Site Specifications (0000003-06-9475) for details on the input DC connections. Information is provided to describe requirements for:
• Input voltage, current and power
• Number and color of DC wires
• DC wire size (AWG and mm2)
2. The product is not provided with a main disconnect device. Therefore, an appropriate disconnect device should be provided as part of the building installation by the customer. The product should be powered by a -48VDC SELV source. One disconnect device is required for each product, and must clearly indicate the product it controls.
In Canada and the United States, a Listed / Certified circuit breaker must also serve as the disconnected device.
3. All AC convenience receptacles in the vicinity of the product should be of an earthing type and the earthing conductors should be connected to earth.
4. Use only copper conductors for field wiring.
5. In the United States, refer to articles 725, 800 and 810 of the National Electrical Code
6. In Canada refer to articles 16, 60, and 54 of the Canadian Electrical Code.
4.2.4 Telecommunications Circuit
1. Do not install the telecommunications line during a lightning storm.
2. For installations where the telecommunication line to other terminal devices, is not intra building, the following must be respected:
• In Canada and the United States, the product is not provided with a secondary protector for the telecommunications line. Therefore, the connection to the telecommunications line should be made through a UL Listed or CSA Certified CSU (Channel Service Unit), or equivalent device which provides secondary protection.
• A Listed primary protector in accordance with the NEC ('96, Section 800-30) must be provided as part of the installation by the customer. The primary protectors must be installed as close as possible to the products.
• In Europe, the product is not approved for direct connection to the telecommunications network. Approved protection must be provided as part of the operator installation.
4.2.5 Environmental
1. The product must not be installed in an area where the local internal environment within the equipment is subject to conductive pollution or to dry non-conductive pollution which could become conductive due to expected condensation. Refer to standard IEC664 "Insulation Co-Ordination for Electrical Equipment Within Low -Voltage System" for details on product deployment limitations
2. The product has been tested for ingress protection with a level of IP20 according to IEC 529 "Degrees of Protection Provided by Enclosures - IP Codes".
3. For details of the expected operating temperature range, refer to document GSM BSC e3 & TCU e3 Site Specifications (0000003-06-9475).
Terms• Core I&C Documents: Core documents required to perform a BSS
initial roll out or its upgrade.
• Product Safety Engineer: member of Nortel Product Integrity group, with experience in the relevant Product Safety standard and local installation requirements.
• Safety Extra Low Voltage Circuit (SELV): a secondary circuit which is so designed and protected that under normal and single fault conditions, the voltage between any two parts of the SELV circuit or circuits and between any one such part and the equipment protective earthing terminal does not exceed a safe value (42.4 V peak, or 60 V DC).
• Telecommunications Network Voltage (TNV): a circuit that, under normal operating conditions, carries telecommunication signals.
