Technical Specifications

Installation Guidelines

• Safety First: Always disconnect system power before installing or removing the module to prevent electrical damage or injury.
• Mounting: Ensure the module is securely seated in the designated S-series backplane slot. Verify that the locking mechanism is fully engaged.
• Environment: Maintain adequate ventilation around the module to ensure operating temperatures remain within the specified -40 to +70 deg C range.
• Handling: Use proper ESD (Electrostatic Discharge) mitigation techniques when handling the module to protect sensitive internal circuitry.
• Wiring: Ensure all input power connections are properly terminated and verified for polarity before applying power to the system.

FAQ

Is this module hot-swappable?

No, the DeltaV power supply modules are generally not designed for removal or insertion while the system power is energized. Always power down the specific segment or rack before maintenance.

What does the conformal coating protect against?

The ISA-S71.04-1985 Class G3 conformal coating provides protection against corrosive airborne contaminants, which is essential for longevity in chemical or high-humidity industrial environments.
