Attaching Surge Suppressor For Control Equipment - Mitsubishi Electric GOT1000 General Description Manual

6.6 Attaching Surge Suppressor for Control Equipment

If an improper operation such as communication error occurs in the
GOT in synchronization with ON/OFF of a particular control equipment
(hereinafter abbreviated to load) such as MCCB, electromagnetic
contactor, relay, solenoid valve, or induction motor, the GOT may be
influenced by surge noise.
In such a case, install the ground cable or communication cable apart
from the load.
If the ground cable or communication cable has to be installed close to
the load unavoidably, attaching a surge suppressor is effective.
Attach the surge suppressor at the position closest to the load.
