8 Electrics
• Heating system power supply: from the boat’s service battery (not the starter batteries for the
driving engine because of the risk of discharge).
• Electrical connection: see device-specific installation instructions.
• Note: all data and safety instructions.
• Fit an operating indication that is clearly visible for the operator that shows whether
the heating is switched on or off.
Note:
• Route all cables and electrical components in dry and protected areas.
• If there are battery isolation switches in the boat: connect the plus lead from the heating system
directly to the positive pole of the service battery. This makes it possible for the heating system
to always be switched off afterwards.
• Power supply cables: keep them as short as possible. If necessary, shorten cables.
• Connecting cable diameter: ≥ 4.0 mm². If supply cable > 7.5 m” ≥ 6.0 mm²
• When extending cables, make sure to use an adequate diameter and insulation type.
• Distance of main fuse from battery positive terminal: ≤ 1 m.
• If highly sensitive electronic devices are on board: note any special electrical screening needed.
