Intended use
The LAE 220 shore power unit provides protection for the onboard AC 230 V/50 Hz system by means of an RCBo 16 A residual current/miniature circuit breaker (Swiss version CH: 13 A). It is designed for use inside the boat, not outdoors. The mains indicator light shows the shore power connection.
The electrical connection is made at the RCBo (RCD/MCB) for phase (L) and neutral (N) and, for the protective earth (PE), via a terminal strip in the housing of the LAE 220.
Connection and wiring diagram
Connect with a cable cross-section of at least 3 × 2.5 mm²; all conductors in the diagram are 2.5 mm².
| Terminal | Function according to the manual |
|---|---|
| 1 | Input phase L (shore) |
| N (input) | Input neutral N (shore) |
| PE | Protective earth, via terminal strip in the housing |
| 2 | Output phase L (onboard system) |
| N (output) | Output neutral N (onboard system) |
Indicator light H1 is connected at the input, in parallel with the AC cables. If the LAE 220 is installed more than 3 m from the shore power inlet plug, an additional miniature circuit breaker (MCB) must be installed close to the inlet; the manual names the LAE 205 for this purpose.
Installation notes
- Work on low-voltage AC 230 V/50 Hz system components may only be carried out by authorised qualified electricians.
- Make all connections to the shore power unit carefully and in accordance with the technical regulations (DIN EN ISO 13297).
- The installation manual is part of the component delivery. Keep it in a safe place for later maintenance work and pass it on to any subsequent owners.

Frequently asked questions
What cable cross-section does the LAE 220 need?
According to the manual, the connection needs at least 3 × 2.5 mm²; the wiring diagram shows all conductors as 2.5 mm². Phase (L) and neutral (N) go directly to the RCBo, the protective earth (PE) to a terminal strip in the housing. Work on the 230 V system may only be carried out by authorised qualified electricians.
Do I need an additional miniature circuit breaker?
Yes, if the LAE 220 is installed more than 3 m from the shore power inlet plug. In that case the manual requires an additional miniature circuit breaker (MCB) close to the inlet; it names the LAE 205 for this purpose. Indicator light H1 is connected at the input, in parallel with the AC cables.
May I install the LAE 220 outdoors?
No. The manual expressly specifies the LAE 220 for use inside the boat, not outdoors. The housing has protection rating IP 65. The unit protects the onboard AC 230 V system with an RCBo 16 A, 30 mA residual current/miniature circuit breaker, and the mains indicator light shows the shore power connection.
What power rating is the LAE 220 designed for?
The input is designed for a shore connection of up to a maximum of 3.6 kW (16 A) at AC 230 V and 50 Hz. The main protection is an RCBo (RCD/MCB) with 16 A and 30 mA. The dimensions are 80 × 150 × 97 mm (W × H × D), and the protection rating is IP 65.
