Note: This connector for software must be used

only by Yokogawa’ s service personnel.

Note: SC450G-A(D)-U

The enclosure is provided with stoppers instead of M20 cable glands for the unused holes. These

stoppers must be removed and replaced by FM approved conduit fittings in accordance with

good installation practice. Also see Appendix 7, Control drawing for FM approval.

3.2 Wiring

3.2.1 Preparation

Refer to figure 3.4. The relay contact terminals and power supply connections are under

the screening (shielding) plate. These should be connected first. Connect the sensor,

outputs and HART

communication connections last.

To open the SC450G for wiring:

1. Loosen the four front plate screws and swing open the cover.

2. The upper terminal strip is now visible.

3. Remove the screen (shield) plate covering the lower terminal strip.

4. Connect the power supply and contact outputs. Use the three glands at the back for

these cables.

WARNING

• Cables that withstand temperatures of at least 75 °C should be used for wiring.

• Wiring work should be performed to meet IP66 or higher requirements. Tighten four

front plate screws to 1.5 N·m torque.

• Use cables that comply with UL2556VW-1 or equivalent.
