Parallel Operation 

9.1 

Principle of Operation 

PROTECT 1. has been designed for parallel operation with n+x 
technology (“n” here stands for the number of units required for 
load supply, “x” for the degree of redundancy). Up to 3 units of 
the same type can be connected in parallel here to increase the 
output power and/or achieve higher availability.
