OVERVIEW
1.1.2. SAFETY INSTRUCTIONS
The CIO ground screw located on the rear of the unit must be correctly grounded.
This is required not only for personal protection, but also for avoiding a voltage difference between the CIO serial port and the master unit port, which could produce anomalies in communication.
GE Multilin will not be responsible for any damage in the relay or connected equipment whenever this elemental safety rule is not followed.
