AS 3015:2022 pdf free download – Electrical installations— Extra-low voltagepower supplies and service earthing within telecommunications networks.
This document sets out requirements for telecommunications ELV power systems and earthing in the
provision of telecommunications networks where —
(a) the telecommunications carrier or entity owns the ELV power supply:
(b) the EIV power supply is located in a restricted access location; and
(C) the ELV power supply Is located In premises and on land that are owned, leased or otherwise occupied in whole or in part by the telecommunications carrier or entity.
This document defines the demarcation points between Standards when used In telecommunications infrastructure.
This document also specifies the minimum requirements for personal safety, equipment safety and safety from lire while maintaining the viability of the telecommunications network.
This document is applicable to the following:
(i) Critical power systems including —
(A) telecommunication facilities;
(B) wireless/radio sites;
(C) small cells;
(D) outdoor cabinets and enclosures:
(F) hybrid fibre-coaxial (HFC) power systems;
(F) pole-mounted Infrastructure; and
(G) security and building management systems associated with information telecommunications Infrastructure [Information Communication Technology (ICT)J.
Single or dual plane power systems.
Float charged battery systems.
Partial state of charge battery systems.
Telecommunications off-grid power systems e.g. solar, wind or fuel cell.
This document does not apply to power systems of the following types —
(A) portable equipment:
(B) electric vehicles;
(C) uninterruptible power systems (UPS) that are in accordance with AS 62040.1.1 and AS 62040.1,2 (with the exception of HFC UPS systems);
(D) non-telecommunications industrial premises; or
Note 3 to entry; The specified conditions are rate oldischarge, final voltage and temperature,
Note 4 to entry Rated capacity normally refers to the rated capacity for a new battery and actual capacrty (14.19.1) normally refers to the capacity that can be obtained from the battery after a period of time where the effects of age reduces the capacity of the battery.
1.4.19.t
actual capacity (of a battery)
quantity of electrical energy, in ampere hours, that can be withdrawn from a cell or battery for a specific set of operating conditions Including discharge rate, temperature, Lnitlal state of charge, age, and final voltage
Note ito entry: Capacity is measured in ampere hours (A h) or in watt hours (W h).
1.4.19.2
rated capacity (of a battery)
quantity of electrical energy in ampere hours, which a cell or battery can deliver after a full charge under specified conditions
Note ito entry: Capacity is measured in ampere hours (A h) or in Watt hours (W h).
1.4.20
charge (of a battery)
operation during which a battery receives, from an external circuit, electrical energy which is then converted into chemical energy
1.4.21
charge (recharge)/discharge rate (of a battery)
current at which a battery is charged or discharged, which may be expressed in amperes or as a multiple of the rated capacity (1.4.19.2) of the battery
Note ito entry: For example, ii a battery Is rated at 500 A hat the 10 h rate of discharge and is being discharged at a current of 50 A. its discharge rate is expressed as 0.1 C1i,.
1.4.22
common d.c. return
DC•C
two-wire
2-wIre
system where only two conductors are required to be connected to the equipment: positive and negative
Note 1 to entry: This Is the case where there Is no earth bonding wire and either the positive or negative conductor is bonded to earth at the ELV d.c., SPC. SIB or SEB tap.off.
Note 2 to entry: This is typically the case when the equipment is internally earthed to the relevant wire that is bonded to the SF.B or SF8 tap-off (usually the positive conductor In a telecommunicatIons facility).
1.4.23
competent person
person who has acquired, through education, training, qualification or experience or a combination of these, the knowledge and skill enabling that person to perform the task required
1.4.24
custom-designed outdoor cabinets and enclosures
cabinets and enclosures that are assembled by the telecommunications carrier or other entity, as opposed to appliances which come to site pre-wired and conform to AS/NZS 62368.1
1.4.25
earth bonding terminal
EBT
earth bar provided as a means of bonding a.c. protective earth to service earth bar (SF8).
