9 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.

NS Hauptverteilung MI main distribution

USV Einspeisung UPS feed

Parallelfeld / Handumgehung plus USV

Unterverteilung

Parallel field / manual bypass plus UPS

subdistribution

This results in the following constellations with n+x technology:

1 + 0 Use of 1 unit max. 10, 15 or

20 kVA

No redundancy

1 + 1 Use of 2 units max. 10, 15 or

20 kVA

Single redundancy

1 + 2 Use of 3 units max. 10, 15 or

20 kVA

Double redundancy

(max. expansion level)

2 + 0 Use of 2 units max. 20, 30 or

40 kVA

No redundancy

2 + 1 Use of 3 units max. 20, 30 or

40 kVA

Single redundancy

(max. expansion level)

3 + 0 Use of 3 units max. 20, 30 or

40 kVA

No redundancy (max.

expansion level)
