Note *: When the case is used for protective grounding, use a 2-core cable.
WARNING
Cables that withstand temperatures of at least 80°C should be used for wiring.
CAUTION
• Select suitable cable O.D. to match the cable gland size.
• Protective grounding should be connected in ways equivalent to JIS D style (Class 3)
grounding (the grounding resistance is 100 Ω or less).
• For maximum use of options, nine cables are required for eight cable entries.
In this case, create a cable using a mixture of two types: AO, DI, or AI. Shielded cables
should be used for any mixed pattern. Never mix with other cables.
NOTE
Grounding of shielded cable
The shielded cables are very effective for noise-rejection, but the grounding of the shielded
cables varies depending on the conditions of use.
One side grounding, which grounds only one end of the shield to ZR802G, requires longer cables
and is effective for noise reduction when there is a potential difference of grounds between the
FLXA402 and the connected device on the other side.
If there is no potential difference between the ZR802G and the device on the other side, it may be
more effective to connect to the ground on both sides.
It may also be effective to connect a capacitor in series to one ground while both sids being
grounded.
