1.1.3 SAFETY INSTRUCTIONS
The F650 ground screw shown in Figure 1–5: must be correctly grounded.
Figure 1–5: LOCATION OF GROUNDING SCREW
Before communicating with a F650 unit through the front serial port, please ensure that the computer is grounded.
In case of using a laptop, it is recommended not to have it connected to its power supply. In many cases it might not be
correctly grounded either due to the power supply or to the connector cables used.
This is required not only for personal protection, but also to avoid a potential voltage difference between the
relay’s serial port and the computer’s port, which could produce permanent damage to the computer or the relay.
GE Multilin will not be responsible for any damage to the relay or connected equipment whenever this elemental
safety rule is not followed.
