INSTRUCTIONS  FOR 

TYPE  5HV-75,  5HV-150,  5HV-250  AND  5HV-'350 

METAL-CLAD  SWITCHGEAR 

5000  VOLT -1200,  2000  AND  3000  AMPERE 

INTRODUCTION 

Instructions for installation,  operation  and main­

tenance  of  type  SHV  metal-clad  switchgear  are 

furnished  with  each  shipment. 

These  instructions  should  be  read  carefully  and 

used  as  a  guide  during  installation  and  initial 

operation. 

File  these  instructions  in  a  readily  accessible 

place  together with drawings  and  descriptive  data 

of the switchgear. The use of these instructions will 

facilitate  proper  maintenance  of  the  equipment 

and  prolong its  life  and  usefulness. 

SCOPE  OF  INSTRUCTIONS 

These  instructions  are  general.  They  cover  re­

quirements  for  installation  as  applied  to  all  metal­

clad switchgear  of  the  5HV-75,  5HV-150,  5HV-250 
and  5HV-350  classification. 

typical  example  is 

show  on the  front  cover. 

Specific information on particular applications is 

furnished  in  the  form  of job  drawings. 

1.  Front  view  showing  arrangement  of  relays 

and  instruments. 

2. 

Single  line  diagram  showing  power  con­

nections. 

3. 

Floor  plan  indicating  available  space  for 

power  and  control  conduits. 

4. 

Section  views  for  each  unit. 

5.  Special  construction  details. 

The  first  sheet  of  the  Bill  of  Material  indicates 

the  application  of  the  drawings. 

TRANSPORTATION 

Prior  to  shipment,  the  SHV  switchgear  under­

goes  careful  factory  inspection  and  crating.  Each 

crate  is  plainly  marked  at  convenient  places  with 

crate  number  and  position.  When  size  or  other 

reasons  make  it necessary to divide  the  equipment 

for  shipment,  the  unit  number  of  the  particular 

equipment  enclosed  is  also  marked  on  the  crate, 
along  with  its  weight.  The  circuit  breakers  are 

shipped  in  individual  crates. 

Immediately  upon  receipt  of  the  switchgear,  ex­

amine  for  any  damage  or  loss  sustained  during 

transportation.  Check  the  contents  again_st  the 

packing list before discarding any packing material. 

If  there  is  any  shortage  notify  the  nearest 1-T-E 

Circuit  Breaker  Company  representative  at  once. 

The 

1-T-E 

Circuit  Breaker  Company  is  not  re­

sponsible  for  damage  after  delivery 

of 

shipment 

to  the  carrier.  However,  if the  company  is notified 

of  such  claims,  it  will  furnish  forms  to  facilitate 
securing  any  adjustments.  If  damage  to  the  ship­

ment  indicates  rough  handling,  claim  for  damage 

should  be  filed  at  once  with  the  carrier  and  the 

I-T-E  Circuit  Breaker  Company  promptly  notified. 

The switchgear housings are crated and shipped 

in  groups  of  one  to  six  units.  Each  group  is  pro­

vided  with  heavy  wooden  skids.  The  remainder  is 

crated  for  protection.  Unloading  and  handling  at 

the  site  is  usually  done  by  placing  rollers  under 

the  skid.  To  avoid distortion to the switchgear,  any 

force  to  move  the  structures  should  be  applied 

to the  skid  by means of crowbar,  block  and  tackle, 

crane,  etc. 

STORAGE 

Remove  crating  from  the  switchgear  units,  but 

leave  each  group  on  its  skid  for  subsequent  mov­
ing.  Uncrate  circuit  breakers  and  accessories. 

Observe  the  following  precautions: 

1.  Check  for  missing  or  damaged  parts. 

2.  Store  in  clean,  dry  place. 

3.  Cover  parts  susceptible  to rust  with heavy  oil 

or grease. 

4. 

Cover  with  heavy  wrapping  paper  to  keep 

dirt  or  dripping  water  from entering.  Dirt  or  mois­

ture may foul working parts or  deteriorate contacts 

and  insulation. 

5.  If  the  switchboard  is  to  be  stored  for  any 

length  of  time,  or  in  any  place  where  dampness 

may  be  present,  then  heaters  should  be  ..:sed  to 

keep  the  switchboard  dry  until it  is placed  in  serv­

ice.  When  outdoor  switchboards  equipped  with 

heaters  are  stored,  the  power  source  for  the 

heaters  should  be  brought  to  the  load  terminals of 

the  ET  thermal  circuit  breaker  or  cutout  device 

which  controls  the  heater  circuits. 

UNLOADING  AND  HANDLING 

The  following  is  a  recommended  method  for 

unloading  and  handling  type  5HV  metal-clad 

switchgear  housings. 

INDOOR  INSTALLATION 

1.  Prior  to  uncrating,  the  switchgear  should  be 

moved near installation site.  This operation may be 
completed by raising switchgear shipping skid with 
track jacks  to allow rollers to be placed under skid. 

2. 

After  switchgear  housings  have  been  mo"Yed 

·to  site,  uncrate 

a.mi 

remove  lag  screws
