Control terminals

The cables should be connected to the control terminal with a mating connector. Input and output terminals
have a functional isolation from terminal to terminal. They are connected to the UPS chassis through
individual 1 MW resistors.
If using a semiconductor switch type, pay attention to the proper polarity. A relay or other mechanical control
is preferred.

Reinforced insulation to the utility is required. The relay output contacts have a maximum rating of
