3.    After  unpacking,  check  whether  the  devices  are  mechanical  damage  caused  by 

transportation. 

 

Kindly Reminder

 

If  UPS  are  found  serious  damage  on  appearance,  further  inspection  must  be  performed  and 

make record on site. Meanwhile, please contact our local branch or agencies immediately.

  Machine Installation   

4.4.1

 

  Machine installation notes 

1.      Do  not  place  in  areas  with  corrosive  gases.  Ensure  that  the  UPS  be  placed  in 

well-ventilated location, to facilitate heat dissipation. 

2

Placed the UPS in a horizontal position, avoid placing in the rugged and sloping areas. Do 

not place objects on top of the cabinet. 

3.    Before wiring, do place the breaker of mainframe on the OFF status. Be sure not to connect Ground line 

and Zero line, Live line and Zero reversely mutually result in short circuit. Ensure good grounding and the 

voltage between Zero line and Ground line must be less than 5 V. If the output of UPS through other adapter, 

quality should be guaranteed to avoid short circuit or open circuit. 

 

4.5    Check the main input

 

Before installation, make sure load capability of grid satisfies the new equipment requirement 

and  the  power  accords  with  the  voltage  and  frequency  on  the  nameplate,  if  current  carrying 

capability declined because of aging of cables. If any doubt, please negotiate the solution with 

the local mains supply department.   

 

4.6    UPS Installation 

4.6.1 KR (6&10kVA) Series UPS installation 

Remove the UPS from bracket to ground for installation. Following are installation examples 

for KR6000.
