WARNINGS & INSTALLATION

Call us for more information on [phone]
ENVIRONMENT
This product should be installed in a heat-resistant, dry, habitable environment.
Prevent the presence of chemicals, synthetic components, curtains or other textiles, etc., in the immediate
vicinity.
WARNING: Do not install within damp or dank indoor or outdoor environments as dampness and even
insects can cause electrical shorting of main board and components which is not covered by the product
warranty. Do not install the batteries directly below the inverter.
CONNECTION OF THE AC CABLING
WARNING: Ensure that the Inverter/Charger is switched to the OFF position via the ON/OFF switch at the
bottom on the unit before connecting cables
WARNING
This is a Safety Class I product (supplied with a protective grounding terminal). Uninterrupted
protective grounding must be provided at the AC input and/or output terminals and/or chassis
grounding point located externally on the product.
The Inverter/Charger is provided with a ground relay that automatically connects the Neutral output to
the chassis if no external AC supply is available. If an external AC supply is provided, the ground relay
H will open before the input safety relay closes. This ensures the correct operation of an earth leakage
circuit breaker that is connected to the output. An uninterrupted grounding can also be secured by
means of the grounding wire of the AC input. Otherwise the casing must be grounded.
NOTE: PROTECTION OF AC-OUT WHEN CONNECTED TO CONTROL PANEL
When the control panel and pumping system are operating normally using mains 230 VAC power,
the electrical circuit is protected by the RCBO on the consumer-board, which will trip if the there is an
electrical fault/defect on the control panel or pump.
During mains power outage, the control panel and pumping system are connected to an independent
power source in the form of the Victron Inverter/Charge which does not have protection built-in to the
unit. Protection of the 230 VAC connection between the Inverter/Charger and the connected electrical
device should be provided by tting the included 30mA RCD Fused Spur by Timeguard. https://www.
timeguard.com/products/safety/rcd-protection-sockets/valiance-rcd-protected-single-gang-white-fused-
connection-unit-passive
The included AV isolator switch should also be tted in-line between inverter/charger and AC device
(panel or pump).
INTERNAL DC FUSES
The Inverter/Charger units include DC fuses. If replacement fuses need to be tted, this should be carried
out by a qualied and competent person.
