Approved Grounds
An ap p roved  g round  is the c losest ac c ep tab le med ium for g rounding  the 
b uild ing  entranc e protec tor, entranc e c ab le shield , or sing le-p oint ground of 
elec tronic  telep hony eq uip ment. If more than 1 typ e of ap p roved  g round  is 
availab le on the p remises, the g round s must b e b ond ed  tog ether as required  in 
Sec tion 250-81 of the National Elec tric al Cod e.
Grounded Building Steel
 
— The metal frame of the b uild ing  where it is 
effec tively g round ed  b y 1 of the following  g round s: ac c ep tab le metallic  water 
p ip e, c onc rete enc ased  g round , or a g round  ring .
Acceptable Water Pipe
 
— A metal und erg round  water p ip e, at least 1/2-in. 
(1.3 c m) in d iameter, in d irec t c ontac t with the earth for at least 10 ft (3 m). The 
p ip e must b e elec tric ally c ontinuous (or mad e elec tric ally c ontinuous b y b ond ing  
around  insulated  joints, p lastic  pip e, or plastic  water meters) to the p oint where 
the p rotec tor g round  wire c onnec ts. A metallic  und erg round  water p ip e must b e 
sup p lemented  b y the metal frame of the build ing , a c onc rete-enc ased  g round , or 
a g round  ring . If these g round s are not availab le, the water p ip e g round  c an b e 
sup p lemented  b y 1 of the following  typ es of g round s:
nOther loc al metal und erg round  systems or struc tures — Loc al 
und erg round  struc tures suc h as tanks and  p iping  systems
nRod  and  p ip e elec trod es — A 5/8-in. (1.6 c m) solid  rod  or 3/4-in. (2 c m) 
c ond uit or p ip e elec trod e d riven to a minimum d ep th of 8 ft (2.4 m)
nPlate elec trod es — Must have a minimum of 2 ft2 (0.185 m2) of metallic 
surfac e exp osed  to the exterior soil
Concrete Encased Ground
 
— An elec trod e enc ased  b y at least 2 in. (5.1 c m) 
of c onc rete and  loc ated  within and  near the b ottom of a c onc rete found ation or 
footing  in d irec t c ontac t with the earth. The elec trod e must b e at least 20 feet (6.1 
m) of 1 or more steel reinforc ing  b ars or rod s 1/2-in. (1.3 c m) in d iameter, or at 
least 20 ft (6.1 m) of b are, solid  c op p er, 4 AWG (26 mm
2) wire.
Ground Ring
 
— A buried  g round  that enc irc les a b uild ing  or struc ture at a d ep th 
of at least 2.5 ft (0.76 m) b elow the earth’s surfac e. The g round  ring  must be at 
least 20 ft (6.1 m) of 2 AWG (35 mm
2), bare, copper wire.

APPROVED FLOOR GROUNDS
!CAUTION:
If the ap p roved  g round  is insid e a d ed ic ated  eq uip ment room, then these 
connec tions must be made by a qualified electric ian.
Floor g round s are those g round s on eac h floor of a hig h-rise b uild ing  that are 
suitab le for c onnec tion to the g round  terminal in the riser c loset and to the 
c ab inet sing le-point g round  terminal. App roved  floor g round s may inc lud e:
nBuild ing  steel
nThe grounding  c ond uc tor for the sec ond ary sid e of the p ower transformer 
feeding  the floor
nMetallic  water p ip es
nPower-feed  metallic  c ond uit sup plying  p anel b oard s on the floor
nA g rounding  p oint sp ec ific ally p rovid ed  in the b uild ing  for the p urp ose
Uninterruptible Power Supply
An op tional UPS (Uninterruptib le Power Sup ply) may b e used for p ower 
hold over. The typ e of UPS d ep end s on the hold over req uirements. Hold over 
times vary from less than 10 minutes to up  to 8 hours. The UPS must p rovid e 
surg e p rotec tion for all c onnec ted c ab inets.
1. Connec t the UPS to an elec tric al outlet c ap ab le of hand ling the p ower 
req uirements of all c ab inets:
a. For 100 VAC, multip ly 4.5 Amp s times the numb er of c ab inets.
b . For 120 VAC, multip ly 3.8 Amp s times the numb er of c ab inets.
c . For 200 VAC, multip ly 2.3 Amp s times the numb er of c ab inets.
d . For 220-240 VAC, multiply 2.0 Amp s times the numb er of c ab inets.
2.Be sure that Cab inet A (c ontrol c arrier) is c onnec ted  to an “ unswitc hed ”  or 
“ always on”  elec tric al outlet on the UPS.

!CAUTION:
The latc h only removes DC p ower from the c ab inet. Unseating  the p ower 
sup p ly removes AC power from the p ower sup p ly, b ut not from the c ab inet. 
To remove AC p ower from the c ab inet, p ull the AC p ower c ord  from the AC

Install Coupled Bonding Conductor 
The Coup led  Bond ing  Cond uc tor (CBC) provid es for mutual induc tanc e c oup ling  
b etween the CBC and  the telep hone c ab les that are exposed  to lig htning . The 
c ond uc tor c an b e a 10 AWG (#25) (6 mm
2) wire tie wrapped to the exposed 
c ab les, a metal c ab le shield  around the exp osed  c ab les, or 6 sp are p airs from 
the exposed cable. 
In a hig h rise b uild ing , c onnec t the CBC to an ap proved  b uild ing  g round  on eac h 
floor. To provid e the c oup led  b ond ing  p rotec tion:
1. Connec t 1 end  of the c ond uc tor to a telephone c able b uilding  entranc e 
p rotec tor g round  that is c onnec ted  to an ap p roved  g round .
2. Route the rest of the c ond uc tor next to the exp osed telep hone c ab les 
b eing  p rotec ted until they reac h the c ross-c onnec t nearest to the 
telep hone system.
3. Position the non-exp osed  telephone c ab les at least 12 inc hes (30.5 c m) 
away from exposed  telep hone c ab les whenever p ossible.
4. Terminate the other end  to the sing le-p oint g round  b loc k p rovid ed  for the 
telep hone system.
Connect and Route Cabinet AC Power Cords
!CAUTION:
The AC power cords may connect to a properly rated power distribution 
unit, ind ivid ual AC p ower rec ep tac les, or to a UPS. See Figure 1-12
.
1. Be sure the c irc uit b reakers at the AC load c enter are 
OFF. 
2.Connec t Cab inet A to an “ unswitc hed ”  or “ always on”  elec tric al outlet.
