For phase zone interconnection cable, see cable specifications on Fig. 3-2. Maximum distance between the first and last
zone should be 250 feet. Route separate from power conductors.
Jumper on devices in last zone used to provide time delay per inverse time overcurrent or short delay time setting. If the
jumper is not used the Digitrip 3000 will initiate trip without time delay (nominally 0.1 seconds).
Up to 10 Digitrip devices may be wired in parallel to provide a single upstream restraint signal.
Only 1 zone common used for both phase and ground.
DO NOT CONNECT ZONE COMMON TO EARTH GROUND.
