4.2.4 Intrinsically Safe Cable Connection

Fig. 4-9: Connection of Intrinsically Safe Terminal Block of the Pressure Switch Unit and Barrier
1) Intrinsically safe cable
1 Cable type (applied):
CVV-S, 1.25 mm² (2, 4, 6, 8, 10, 12 cores),
CVV-SB, 1.25 mm² (2, 4, 6, 8, 10, 12 cores), or
UL2586-SB, 1.25 mm² (2, 4, 6, 8, 10, 12 cores)
(SUMIDEN HITACHI CABLE Ltd.)
- The cable to be connected with terminal blocks
P1 to N3, and 1 to 2 are different.
- P1 to N3 and 1 to 2 are separated by the shield.

Note) The barriers between P2 and N2 in the DX200 are
short-circuited by the wire.
Do not remove the wire.
On the manipulator side, however, since a short-circuit
does not exist, there is no wire.
Also, no wiring exists on each manipulator side and
the DX200 side between P2 and between N2.
