COMPACT POWER LINE SHELVES – MODEL J85480S1
• The CE mark if provided on the product is applied to show conformance to the requirements outlined in the European Union’s
Low Voltage Directive {2006/95/EC} and EMC Directive {2004/108/EC}.
• The J85480S1 shelf has been evaluated for hot swapping.
• A separate protective Earthing terminal is provided at the rear of the shelf
– the building installation shall provide a means for connection to protective earth; and
– the equipment is to be connected to that means; and
– a SERVICE PERSON shall check whether or not the socket-outlet from which the equipment is to be powered provides a
connection to the building protective earth. If not, the SERVICE PERSON shall arrange for the installation of a PROTECTIVE
EARTHING CONDUCTOR from the separate protective Earthing terminal to the protective earth wire in the building.
Output Connections
• All field wiring should comply with the U.S. National Electrical Code (NEC) and/or applicable local codes/standards.
• Routing of the DC output cables should guarantee that cables are not in contact with sources of heat and surfaces that may
damage the cable insulation.
• The DC output is not provided with a fuse or circuit breaker suitable for branch circuit protection. Therefore, the power shelf
should be mounted in the same rack or cabinet as the equipment being powered. Use interconnecting power cables suitable for
the application and sized to carry the rated output current. The interconnecting cables should be capable of carrying the overload
current and short circuit current without damage or risk of fire.
• The output for the system is SELV and has available power greater than 240VA.
• Insulation on output field-wired conductors should be rated no less than 90°C. Wiring internal to enclosed equipment cabinets
should be rated at 105°C (minimum). The provided DC output cords (red and black wires) are rated for 105°C.
• Before opening the insulating cover to gain access to load and ground connections, ensure all power supplies are disconnected
from the AC MAINS.
AC Input Connections
• AC branch circuits to this equipment must be protected with fuses or circuit breakers sized as required by the U.S. National
Electric Code (NEC) and/or local codes. Up to four AC mains power cords are required to power the shelf (one for each rectifier).
Each power cord should be connected to a separate AC mains branch circuit with an overcurrent protector rated at no more than
20A, except for the L22 and L23 shelves that should be protected by an overcurrent protector rated at no more than 15A.
• The power supply mains inlet may be used as the means to provide AC protective earthing.
• An accessible AC disconnect/protection device to remove AC power from the equipment in the event of an emergency must be
provided. An accessible socket-outlet/receptacle installed near the equipment is also acceptable as a disconnect.
• The equipment is powered by multiple AC inputs (one per rectifier). Disconnect all AC sources of power before servicing.
• These units are to be used with TN-S power systems only.
Safety Symbols and Guidelines
Read and understand all instructions before attempting any installation of this product. When installing, operating,
or maintaining the J85480S1 Power System, basic safety precautions should always be followed to reduce the risk
of fire, electric shock, and injury to persons. Such precautions include the following:
This symbol identifies the need to refer to the equipment instructions for important information.
This symbol identifies the presence of hazardous AC or DC voltages or hazardous energy levels.
In the context of this product
 The DC output cables contain electrical energy levels capable of causing heating and
arcing if shorted to metal objects. Make connections with the power disconnected.
 Hazardous AC voltage and DC electrical energy is contained within the enclosure of the
power shelf. No user or field serviceable parts inside.
This symbol is used to identify safety earth ground connection points within the equipment.
