TC500K3US-O Installation Instructions

 

54 

8 Electrical Connection 

This  chapter  introduces  the  methods  and  precautions  of  the  electrical 

connection of TC500K3US-O. The installer shall use National Electrical Code, 

ANSI/NFPA 70 wiring methods all the field wiring. 

8.1 Precautions 

The electrical connections are conducted after the installation and fixation 

of  the  inverter,  and  note  the  requirements  of  connections  and  precautions  of 

this chapter in the electrical connections. 

 

The DC side voltage of TC500K3US-O DC is up to 600Vdc, AC side 

voltage reaches 200Vac. 

Do not touch any live parts! 

 

Make  sure  that  AC  and  DC  sides  are  uncharged  before  installation 

and maintenance. 

 

As the  temperature of  TC500K3US-O is partly high,  TC500K3US-O 

and flammables and explosives shall not be piled together.
