Paradyne Hotwire 8620 GranDSLAM Installation Guide manual Important Safety Instructions

!Important Safety Instructions

1.Read and follow all warning notices and instructions marked on the product or included in the manual.

2.The AC product version is intended to be used with a 3-wire grounding type plug — a plug which has a grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by modifying the plug or using an adapter.

Prior to installation, use an outlet tester or a voltmeter to check the AC receptacle for the presence of earth ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician has corrected the problem.

If a 3-wire grounding type power source is not available, consult a qualified electrician to determine another method of grounding the equipment.

3.Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from overheating, these slots and openings must not be blocked or covered.

4.Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the power cord.

5.Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel.

6.General purpose cables are provided with this product. Special cables, which may be required by the regulatory inspection authority for the installation site, are the responsibility of the customer. To reduce the risk of fire, use a UL Listed or CSA Certified, minimum No. 26 AWG telecommunication cable.

7.When installed in the final configuration, the product must comply with the applicable Safety Standards and regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

8.A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action prior to interconnecting the products.

9.Input power to the DC configuration of this product must be obtained from a SELV (Safety Extra Low Voltage) source (less than 60 VDC, and double insulate from hazardous voltages).

10.If it becomes necessary to replace either of the accessible A or B fuses (located on the front panel): For continued protection against fire and/or shock, replace the fuse with the same rating, manufacturer, and manufacturer’s part number as originally installed in the unit. These fuses are readily available through your local Paradyne distributor, or you may order replacement fuses by contacting Paradyne directly.

11.When powered by –48 VDC, this product may only be used in a Restricted Access Location in accordance with articles 110-16, 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70. A Restricted Access Location is a secure area (dedicated equipment rooms, equipment closets, or the like) for equipment where access can only be gained by service personnel or by users who have been instructed about the reasons for the restrictions applied to the location and about any precautions that must be taken. In addition, access into this designated secured area is possible only through the use of a tool or lock and key, or other means of security, and is controlled by the authority responsible for the location.

—For DC operation: Connect the 48 VDC SELV supply source that is electrically isolated from the AC source. The 48 VDC source is to be reliably connected to earth. Connect the earthing (grounding) lug terminal located on the back of the 8620 GranDSLAM chassis.

—For DC operation: A readily accessible disconnect device as part of the building installation shall be incorporated in fixed wiring. The disconnect device (a 48 VDC 15–20A circuit breaker or switch) must be

included with a 15–20A, 48 VDC fuse or circuit breaker in the ungrounded connector. Use a minimum 14–18 AWG or 2.5 mm2 fixed power source wires with strain retention.
