The Galvanic Isolator simply connects to EITHER end of your shore line. It can be connected either at the boat end or the shore end. Both options work equally well. - Page 3 Installation - Fixing the Isolator continued As a further measure to prevent water ingress, when fixed, apply a little sealant to the heads of the fixing screws. If the lid has been disconnected, re-connect the terminals, ensuring that they are pushed fully home. Re-fix the isolator lid.
- Page 4 Model Gi-120/BK only The LED's on your isolator inform you about any faults with your boats Earthing arrangement. Illuminated LED's NEVER indicate a faulty isolator. Both Lights OFF: Normal operation. No action required – just check back occasionally to ensure that all’s well.
- Page 5 Occasionally, when you fit a Status Monitored galvanic isolator, both of the warning lights may glow straight away. If both lights are illuminated on your galvanic isolator, you have AC earth leakage. You do NOT have a faulty isolator. In fact, your isolator is alerting you to a potentially dangerous situation that you may not previously have been aware of.
- Page 6 Model Gi-120/BK only hen you have traced the fault to a single appliance or circuit, it must then be checked for earth leakage by a competent person. Imprinted Leakage Imprinted Leakage typically occurs when equipment using a Switched Mode Power Supply Unit, (SMPSU), is connected to your system.
