Installation Guidelines

• Enclosure Requirements: Install the open-type equipment inside a secure environmental enclosure that requires a tool or key to open.
• Transient Voltage Regulation: Ensure provisions are implemented to limit power supply transient voltages to less than 140% of the peak rated power supply voltage.
• Power Limitations: Power must be supplied through a certified power distribution board that limits the available current to 3.5 A maximum.
• Terminal Wiring: Strip field wiring insulation locally without adding intermediate components other than standard bare conductor replication parts such as ferrules.
• Wiring Standards: Apply appropriate Class I Division 2 or Zone 2 wiring methods conforming to local codes and authority regulations.
• Screw Torques (Euro Blocks): Secure connections to a nominal torque of 4 in-lb (0.45 Nm) for wire sizes from 24 AWG to 12 AWG.
• Screw Torques (Barrier Blocks): Secure connections to a nominal torque of 9.6 in-lb (1.1 Nm) for wire sizes from 22 AWG to 12 AWG.
