An Earth to Frame Ground (FG) must be prepared when the unit is installed in a rack assembly.
Prepare Grounding Cable
The following information should be taken into consideration when preparing grounding wires.
•
Determine the proper length and prepare Frame Ground.
•
Use IV (insulated vinyl) wire that is compatible with the supplied crimp connector (.057 ~ 1.44mm
2
) e.g.
AWG cross-section 0.8mm
2
.
•
If a crimp connector other than the one supplied with the BV1270SIP-OD unit is to be obtained, use one
that is 1.25-4 for use with a 4mm diameter screw and terminal part width of 8mm or less.
Do not use an angular type connector.
Connect Frame Ground and Signal Ground Cables
All unit chassis must be grounded to a Communication 1 earth ground.
To connect the Frame Ground:
1.
Use the terminal screw located at the rear of the base unit and to the left of the power connector to secure one
end of the FG grounding cable.
2.
Connect the other end of the frame grounding cable to a protective earth grounding point.
