Installing the FAAC J355 HA M50 automatic retractable hydraulic bollard (FAAC part number 116351) requires rigorous civil and structural planning to maintain certified crash resistance under PAS 68 and IWA 14-1 standards. Because the foundation absorbs dynamic impact forces up to 1,852,000 Joules, excavation geometry, reinforcement rebar placement, and concrete casting must strictly follow manufacturer engineering specifications.
Civil Works and Excavation Sizing
Installation begins with an excavation pit measuring approximately 3,100 mm in length, 1,600 mm in width, and 1,850 mm in depth. This space accommodates the dedicated FAAC J355 foundation pit assembly (FAAC part 116130) and the surrounding reinforced concrete cage. Rigging hardware suitable for handling heavy industrial equipment must be deployed on-site, as the foundation pit alone weighs approximately 235 kg, while the bollard mechanical assembly weighs approximately 850 kg.
| Installation Parameter | Specification / Dimension |
|---|---|
| Excavation Dimensions (L x W x D) | 3,100 mm x 1,600 mm x 1,850 mm |
| Foundation Pit Weight (Part 116130) | Approximately 235 kg |
| Bollard Body Weight | Approximately 850 kg |
| Cylinder Diameter | 355 mm |
| Cylinder Extension Height | 1,200 mm above ground level |
| Hydraulic Power Unit Protection | IP67 rating (integrated in bollard) |
Pit Positioning and Hydraulic Drive Architecture
The foundation pit must be leveled and aligned flush with finished grade elevation prior to concrete pouring. The FAAC J355 HA M50 eliminates the need for underground pressurized hydraulic hoses between an external cabinet and the cylinder; its hydraulic drive unit is integrated directly inside the bollard assembly. This self-contained architecture prevents pressurized oil transfer ducts beneath the driveway surface, reducing fluid leakage risks across perimeter lanes.
During assembly, the hydraulic system requires 7 liters of FAAC HP hydraulic oil to power the hydraulic circuit, generating up to 9,000 N of thrust force. For cold-climate installations where ambient conditions fall below -15 °C, the optional pit heater JH275/J355 (FAAC part 116203) can be installed within the pit casing to maintain fluid viscosity and allow operation down to -40 °C.
Electrical Supply and JE275 Control Board Integration
Electrical routing requires dedicated mains feed conduit routed directly into the pit base before the concrete pour. The primary drive mechanism operates on a 220–240 V AC supply at 50/60 Hz, demanding a maximum operational power load of 3,900 W (3.9 kW). Dedicated bollard management is executed using the external FAAC JE275 electronic control board (FAAC part 116300), which oversees one single J355 HA unit per board.
- Power Infrastructure: Supply 220–240 V AC (50/60 Hz) capable of sustaining a 3.9 kW peak load.
- Control Board Architecture: Interface the drive motor, integrated limit switch regulation (MX50-30BB), and built-in perimeter LED warning crown to the JE275 control unit.
- Multi-Unit Synchronization: Interconnect individual JE275 controllers in Master/Slave network topologies when operating multi-bollard access control arrays across vehicular lanes.
- Emergency Fast Operation (EFO): Route auxiliary connections if deploying the optional EFO hydraulic circuit, enabling 2-second ascent over the standard 6-second cycle.
- Manual Lowering Integration: Fit the optional FAAC J355 manual release kit (part 116102) to permit controlled mechanical descent during complete electrical outages.
