12 Electrical Connections
Note! During any work with the electrical connections the mains power and the electrical battery must be disconnected.
- Place the electric switch easily accessible from the operator.
- If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

12.2.1 Power supply unit (PSU 75W)
12.2.2 Drive unit
GR 63x25 (ND 40V, gear ratio 10:1, Pitch 5mm)
12.2.3 Main control unit (MCU)
The MCU has a label - main control type label including Hardware information and Software information.
- The hardware information states revision of the MCU and applies to PCB or hardware changes.
- The software information states the software version.
12.2.4 Connection of electrical units
This section details the connections between the PSU, Drive unit, MCU, and Battery.
Mains / PSU Connection
| Mains power | 100-240 VAC, 50/60Hz, fuse 10AT |
| Wire Colors | Red, Black, Earth, Neutral, Live |
Control Inputs (MCU Terminal Block)
| Signal / Function | Voltage / Type |
|---|---|
| Lock | (+) Lock, (-) 0VDC |
| Inner impulse | (+) 24VDC, (-) 0VDC |
| Key impulse* | *Can generate battery wakeup |
| Presence monitoring | Presence impulse 1, Presence impulse 2 |
| Outer impulse | (+) 24VDC, (-) 0VDC |
| Side presence monitoring | Side presence impulse 1, Side presence impulse 2 |
| Stop impulse | (+) 0VDC |
12.3 Connection of the sensors and the other accessories
Refer to the sensor manual for installation and adjustments. The protective device must comply with EN 12978.
Note! Make sure that the cable from the sensor installed on the cover does not interfere with the lock unit. If it does, drill a new hole for the sensor cable.
12.3.1 MA111-1, KS-S, KS-F, magnet switch
| Sensor Function | Connection | MCU Terminal |
|---|---|---|
| Inner impulse | (-) 0VDC | Inner impulse |
| Outer impulse | (-) 0VDC | Outer impulse |
| Stop impulse (NO) | (-) 0VDC | Stop impulse |
| Stop impulse (NC) | Stop impulse monitoring | Stop impulse (monitored) |
| Key Impulse | (-) 0VDC | Key Impulse |
Configuration: Stop impulse NC requires MCU setting 46=01. Monitoring requires 66=01.
12.3.2 SA52
| Wire Color | Function | MCU Connection |
|---|---|---|
| Green | (+) 24VDC | Power |
| Yellow | (-) 0VDC | Ground |
| Brown | Signal | Inner impulse (Inner sensor) |
| White | Signal | Outer impulse (Outer sensor) |
12.3.3 SBK-111 NPN/N (Normally Closed)
| Component | Wire Color | Connection |
|---|---|---|
| Receiver/Transmitter | Brown | (+) 24VDC |
| White/Green | (-) 0VDC | |
| White | Presence impulse 1 or 2* | |
| *If only one presence sensor is used, connect to MCU-TB:9. Use presence impulse 2 only when presence impulse 1 is already used. | ||
| Stop Impulse | White | Stop impulse / Stop monitoring |
Configuration: Logic setting likely requires MCU adjustments (e.g., 7=01, 8=01, 45=01, 46=01, 66=01).
12.3.4 SBK-111 NPN/R (Normally Open)
