Product Introduction

The BENTLY 3500/15 106M1079-01 serves as the universal AC power supply module for the Bently Nevada 3500 monitoring framework. It accepts a wide 85 to 264 Vac rms input range and converts it to the specific DC voltages required by internal monitoring and communication modules.This module enables hot-swapping when a second power supply is installed in the adjacent slot. Field data shows that maintaining a 20% power capacity margin above the calculated framework load prevents voltage sag during peak module draw.

Installation & Configuration Guide

Preparation (10 min)
Verify the incoming AC voltage falls within the 85-264 Vac rms range using a multimeter. Review the 3500 hardware manual to confirm the 3500/15 module is designated for the leftmost power slot. Ensure the rack is properly grounded.Removal (5–10 min)
If replacing a failed unit in a dual-power setup, simply pull the release latch and extract the module. If operating a single power supply, you must schedule a maintenance window. Power down the entire 3500 framework before removal to prevent data loss or module damage.Installation (10 min)
Align the 3500/15 106M1079-01 with the backplane guides. Push firmly until the front panel seats flush against the rack. Engage the locking latch. Verify that no cables obstruct the module’s ventilation path.Power-On & Test (10 min)
Restore AC power to the module. Observe the front panel LEDs. A solid green indicator confirms normal operation. If the LED is red or flashing, check the input voltage and verify the module is fully seated. Run a framework self-test via the 3500 configuration software to confirm all downstream modules are receiving correct voltage.

 

Troubleshooting Quick Reference

• Red Power LED: Check incoming AC voltage first. Measure at the terminal block. If voltage is nominal (120V/230V), the module has likely failed internally.
• Framework modules not booting: Verify the 3500/15 is installed in the correct leftmost slot. A module in the wrong slot will not distribute power correctly.
• Intermittent resets: Calculate total framework power draw. If approaching the 2.3A rms maximum output limit, add a redundant power supply or reduce module count.
• No LED illumination: Check for a tripped upstream circuit breaker or blown fuse. Inspect the AC input terminal block for loose connections or burnt pins.
• Communication errors: Power supply ripple can corrupt backplane data. Measure DC output ripple with an oscilloscope if other modules report bus faults.

Dimensions, Mounting & Wiring Notes

• Dimensions (H × W × D): 120.7 mm × 50.8 mm × 251.5 mm
• Mounting Method: Slides into standard 3500 framework backplane; secured by front-panel latch
• Terminal Notes: AC input connects via rear terminal block. Use appropriate wire gauge for the 85-264 Vac input. Torque terminal screws to manufacturer specification to prevent thermal runaway at connection points.
• Slot Position: Must occupy the leftmost power slot in the 3500/05 framework. Framework interface module (3500/20) occupies the second leftmost slot.

 

FAQ

Can I hot-swap the 3500/15 106M1079-01 while the rack is powered?
Only if a second power supply is installed and operational. Single-supply configurations require a full rack shutdown. Always verify redundancy status in the software before attempting removal.I’m seeing a flashing amber LED on my power module. What does that mean?
That usually indicates an over-temperature or over-current condition. Check the cabinet cooling fans immediately. I’ve seen this happen when rack filters get clogged with dust over time.Is this module compatible with older 3500/05-01 frameworks?
Yes, the 106M1079-01 is backward compatible with standard 19-inch and mini 12-inch 3500 frameworks. However, always verify your specific framework revision against the Bently Nevada compatibility matrix before ordering.Do you offer bulk pricing for plant-wide upgrades?
Yes. We provide tiered pricing for quantities of 5 or more units. Contact our sales team with your exact quantity and required lead time for a formal quote.What happens if I install this in the wrong slot?
The module will not function and may prevent the framework from powering up. The 3500/15 must be in the leftmost slot, followed by the 3500/20 interface module. Refer to the installation diagram in the hardware manual.How long is the warranty on refurbished units?
All tested and refurbished units carry a 12-month functional warranty. This covers manufacturing defects and verified functional failures under normal operating conditions.Can I use this with DC input instead of AC?
No. The 106M1079-01 is specifically a universal AC power supply. For DC input applications, you must use the dedicated DC power modules (e.g., 129486-01 for high-voltage DC or 133292-01 for low-voltage DC).
