Cabinet
• In the AFV40S/AFV40D, and ACB51, the channel base is isolated from the cabinet by a
Bakelite sheet (t=5 mm) to allow one point grounding.
• The grounding bar (1) to connect a grounding cable is located at the bottom of the cabinet
near the front panel and it is electrically connected to the cabinet.
• The grounding bar (2) for shielding the inside of the cabinet is on the bottom of the cabinet
near the back panel, which is isolated from the cabinet. Another grounding bar (3) for
shielding the inside of the cabinet is on the bottom of the cabinet near the front panel.
• The grounding bars (2) and (3) are connected to the grounding bar (1) by a cable of 5.5 mm
2
(This is used for grounding shields of input/output cables).
• When the grounding bars must be grounded separately depending on the purpose
(for shielding and for connecting a grounding cable), disconnect the cable between the
grounding bar (1) and (3) or (1) and (2), then ground separately.
