Overview
Electronically, the 380A is identical to the I-380 — it carries the same 380 V three-phase direct-drive board. The one thing that separates them is the cabinet structure: where the I-380 arrives as a wall-type control box with a cover, the 380A is delivered as the open-board variant of this portfolio and integrated straight into the facility’s main fuse panel. That approach slots neatly into the central control panel architecture of large facilities.
380A vs I-380 — structural difference
| 380A | I-380 | |
|---|---|---|
| Electronics | Same (380 V direct-drive) | Same (380 V direct-drive) |
| Structure | Open board | Covered control cabinet |
| Buttons | None (from panel exterior) | Open / Close / Stop integrated |
| Installation location | Fuse panel / site cabinet | Wall (near the door) |
| Site user access | Only technician | Operator can access |
| Installation | Panel electrician required | Mechanical technician |
Why open board?
In large industrial facilities, the central control panel philosophy is widespread:
- All motor controls are gathered in a single fuse panel.
- Standard DIN rail + 35 mm slot installation inside the panel.
- Operator buttons are taken outside the panel (to a control point above the panel or to a site button cabinet).
- During maintenance the panel cover is opened from a single point; there is no separate door/cabinet for each motor.
380A is suitable for this approach — comes as a DIN rail-mounted board instead of the cabineted version of I-380.
High voltage — safety critical
Because 380A is an open-board structure, the high-voltage bars on the board are directly visible. This situation:
- Only qualified technician access is mandatory.
- It is used with the panel cover closed; when opened for maintenance, all energy must be cut absolutely.
- The IP protection class is sufficient for inside the panel (IP20 typical), should not be located outside the panel.
Target projects
- Large industrial facility (5+ doors controlled from a single panel)
- Automotive production factory
- Logistics terminal central control room
- Organised industrial zone (OSB) main entrance + service entrances
- Port + free trade zone multi-door systems
Field discipline
- All energy must be cut before touching the high-voltage bars on the board. This is the most critical safety rule — during maintenance/installation the panel main breaker must be pulled, in a multi-phase installation each phase must be checked with a separate meter.
- DIN rail installation — Fixing on a standard 35 mm DIN rail. The slot requires 4-6 module widths.
- Clamp labelling — In a multi-motor panel, each clamp group must be clearly labelled with which door it is connected to.
- Earthing — A single earthing bar inside the panel; all motor chassis are connected here.
- Button + signal cables — A 0.75-1 mm² screened cable is recommended for operator buttons outside the panel (against noise).
Model notes
All energy must be cut before touching the high-voltage bars on the board. In single-motor / small-facility installations, the I-380 cabineted version is more practical; in multi-motor + central panel philosophy, the 380A open board is preferred.
Frequently Asked Questions
Below we've compiled the most common questions and answers regarding this product.
-
All LEDs are normal on the r-tec board but the motor does not move and hums/makes noise
The symptom indicates that power is not fully reaching the motor: a loose or detached supply lead at the motor output terminal, or a lost phase on a three-phase supply. First step: cut the power and check that the connections at the motor output terminal are tight. If the cables are in place, measure the voltage across the motor output leads; on a three-phase (380 V) board the nominal voltage (380 V) should be present between each pair of phases. If a phase or voltage is missing, review the supply and terminal connection with an authorized person.
-
r-tec control board: the door/boom moves the wrong way (towards closing) on an open command
Cause: the motor rotation direction is wired in reverse. First step: cut the power; on DIP-switch boards such as GATE 24, change the direction DIP switch (typically no. 4); on sliding/three-phase boards, swap any two of the motor supply leads to correct the direction. Always cut the power before working; after the direction change, re-confirm the limit/encoder learning at the closed and open ends.
