2.4.5 Cable Wired to GD40

Detector
The cable wired to the GD40

detector comes from the GD402 converter. Use a shielded cable
of 10 to 13.5 mm in finished outer diameter that suits the dedicated cable gland. Wire the cable
through the cable gland, being careful not to connect the cable with the wrong polarities. Attach
M4 crimp terminals to the ends of the core wires (see Figure 2.14). Connect the shielding wire to
terminal 13 on the converter (see Figure 2.12). When crimping the terminals, use tools that fit the
terminals.
If a malfunction occurs and it is assumed to be due to noise, use a double-shielded cable (for
example, the cable with Yokogawa’s Model GDW-L
  
). Connect the outer shielding wire
to terminal 13 on the converter and the other end of the wire to the grounding terminal on the
detector. Connect the inner shielding wires to the grounding terminal on the converter (see Figure
2.17).

2.4.6 Wiring to Model EJX310A pressure transmitter
When Wiring to model EJX310A pressure transmitter, connect by using cables from GD420
o
converter. Wire the cables through cable glands. Be sure not to misconnect polar. For finished
external diameter, refer to Figure 2.11, "Terminals on the Converter."
The size of the terminal screw threads is M4. Use a crimp terminal suited for your cable terminal.
