Cable entries •
Cable gland: M20 × 1.5 with cable Æ 6 to 12 mm (0.24 to 0.47 in)
• Thread for cable entry: ½" NPT, G ½"
Cable specification •

• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the
plant.
