In a parallel module system a control bus, formed by RJ45
terminated cables, is connected between all the UPS
enclosures in a ‘ring’ configuration.
The cables are held in-situ by a metal clamp which is secured
by two screws, as illustrated.
Note that, although in practice the UPS modules are usually
positioned close to each other, the maximum parallel bus cable
length is 7m.
