5. X80 Power Supply Selection Comparison within the Same Series

Selection Conclusion for Replacement

1. Downward Replacement: BMXCPS2000 can be used if total load <20دبليو, but sensor power capacity is halved; not directly interchangeable for high-load systems.
2. Upward Replacement: No higher-power AC-input X80 power supply available. Multiple BMXCPS3500 units shall be configured for separate racks in multi-rack systems.
3. Low-temperature Applications: BMXCPS3500H is mandatory for field temperatures below 0℃; معيار 3500 will derate or trigger faults at low temperatures.

9. Troubleshooting Matrix

8. تثبيت & حظر الأسلاك (Hard Rules)
9. Do not share the same circuit with high-power inverters and contactors; separate isolated power supply is required.
10. Sensor 24V cables shall not be routed in the same trunking as power cables to avoid interference.
11. The module must be reliably connected to PE protective earth; otherwise EMC interference may cause false alarms.
12. Total load of a single 3500 unit is strictly limited to 36W max; separate power supplies must be used for multiple racks.
13. Do not plug/unplug the module during operation (no hot-swap design); replace only after power cut-off.
14. Compatible Backplanes

Fully compatible with all BMXXBP X80 backplanes: BMXXBP0400 / 0600 / 0800 / 1200, إلخ.

Incompatible: Old-generation Quantum BMEXBP series backplanes; mixed use is forbidden.

Complete Installation Specification for Schneider BMXCPS3500

1. Core Installation Structure (Two Layers)

1.1 Base Layer: 35mm Standard DIN Rail Mounting (Cabinet Rear Panel)

The unit is equipped with a built-in DIN35 standard snap-on base, compatible with national standard 35mm electrical mounting rails (AM1 ED rail).

Module width: 35مم, single-slot occupation; dimensions: 242.4 (ح) × 35 (دبليو) × 110 (د) مم

Snap structure: Dual upper & lower elastic snaps for rail fastening without screws; top/bottom latches prevent detachment

Rail mounting steps:

1. Secure 35mm DIN rail to cabinet rear panel, ensure rail is level and undeformed
2. Hook the module’s bottom snap onto the lower edge of the rail first, then push the upper part of the module upward until a “انقر” sound confirms full engagement
3. Fully lock both upper and lower snaps; no vertical looseness under pulling force. لإزالة, pry open upper/lower snaps with a flat screwdriver.

1.2 Upper Layer: X80 Dedicated Backplane Slot Installation (Core Rack Power Connection)

BMXCPS3500 must be inserted into BMXXBP series X80 rack backplanes to supply power to CPU and I/O backplanes; standalone operation without backplane is not allowed.

Compatible Backplane Models

Only compatible: BMXXBP0400 / 0600 / 0800 / 1200 (including H wide-temperature variants)

Mixed Use Forbidden: Old BMEXBP…02 Quantum backplanes with mismatched physical connectors.

Standard Backplane Mounting Procedure (Power Off Mandatory, Hot Swap Prohibited)

1. Cut off power to the whole unit and disconnect AC input
2. Align the metal guide slots on the rear of the power module with upper/lower rails of the rack backplane, slide horizontally smoothly to the bottom of the slot
3. After full insertion, backplane bus gold fingers are fully mated; front face of the module aligns flush with other I/O modules
4. Built-in left & right locking latches on the module, snap inward to lock onto the rack and prevent loosening under vibration
5. Power supply shall be installed in the 1st leftmost slot of the rack as priority (Official recommended layout); one CPS3500 for each independent backplane in multi-rack systems.
6. Mounting Attitude & Tilt Restrictions
7. Standard Attitude: Vertical upright installation (cabinet rear panel vertical, module vertical top-to-bottom) for vertical convection cooling airflow, optimal heat dissipation
8. Allowable Tilt: Full-load operation permitted within ±30° panel tilt; derating required if tilt exceeds 30°, cabinet internal temperature ≤40℃
9. Strictly Forbidden: Horizontal flat or upside-down mounting – airflow blocked, frequent overtemperature tripping, drastically shortened service life.
10. Mandatory Heat Dissipation Clearance Requirements (Hard Installation Gaps)

The module relies on natural air cooling via top & bottom ventilation holes; clearances must be reserved:

Above & below the module: ≥20mm free space, unobstructed by cable ducts or other components

Left & right sides of the module: ≥10mm, no tight contact with adjacent modules

Horizontal distance between heat-generating components (العاكسون, المقاولين) and power supply inside cabinet ≥50mm

Cooling fan recommended for sealed small cabinets; replace with BMXCPS3500H wide-temperature model if ambient temperature >55درجه مئوية.

4. Terminal Accessory Installation (Wiring Matching Parts)

Standard factory supply: Screw-type terminal block BMXXTSCPS10; Spring push-in terminal block BMXXTSCPS20 available as separate order.

1. 5-pin main power terminal (L/N/PE/24V circuit/Sensor 24V): Insert horizontally into lower front interface of module, lock via built-in snap
2. 2-pin alarm dry contact terminal: Adjacent to the right of 5-pin terminal, used for fault alarm output
3. Terminal Removal: Pinch both side snaps of terminal and pull straight outward; diagonal pulling is prohibited to avoid broken pins.
4. بيئة التثبيت & Protection Specifications
5. Protection Class IP20, cabinet installation only; no direct exposure to outdoor environment, dust or moisture.
6. Flat, burr-free mounting surface; firmly fixed DIN rail; rail end stops required for high-vibration operating conditions.
7. PE protective earth wire must be reliably connected to cabinet earth bar to reduce EMC interference.
8. No power derating required for altitude ≤2000m; 10% load derating mandatory above 2000m.
9. Installation Prohibitions (Absolute Forbidden Operations)
10. Plug/unplug module or wiring terminals while powered – risk of burning backplane bus and power supply.
11. Unlocked fixing latches cause poor backplane contact and system shutdown under long-term vibration.
12. Insufficient top/bottom heat dissipation space or close contact with cable ducts triggers overtemperature protection under high temperature.
13. Upside-down / flat mounting blocks cooling airflow.
14. Mixed use of old BMEXBP backplanes with mismatched physical connectors; forced insertion damages gold fingers.
15. Single power supply driving multiple independent backplanes leads to overload protection triggered when total power exceeds 36W.
16. Supplementary Redundant Power Supply Installation (Multi-Power Scenarios)

For redundant power supply, install one BMXCPS3500 in two separate slots of the same rack, each fed by an independent AC circuit. The backplane performs automatic redundant switching. Reserve ≥15mm heat dissipation gap between the two power supplies.
