Sure, here are the some tips for proper installation of the MultiPlus-II:
-
Location: Install it in a dry, well-ventilated area, close to the batteries, ensuring at least 10 cm of clear space around for cooling.
-
Ambient Temperature: Be mindful of the ambient temperature. High temperatures can reduce service life, charging current, and peak capacity, or even cause the inverter to shut down.
-
Positioning: Avoid positioning the unit directly above lead acid batteries to prevent damage from corrosive gasses. Wall mounting is recommended on a solid surface like concrete or masonry.
-
Accessibility: Ensure the interior of the product remains accessible after installation for maintenance or inspection.
-
Cable Voltage Losses: Minimize the distance between the product and the battery to reduce cable voltage losses.
-
Heat-Resistant Environment: Install in an environment resistant to heat and away from chemicals, synthetic materials, curtains, or textiles.
-
Disconnecting Mechanism: The system must have a way to disconnect both AC and DC circuits. Use circuit breakers or fuses as appropriate, and ensure that disconnect switches are in place if fuses are used.
-
Battery Compatibility: Only charge Lead Acid or LIFEPO4 type rechargeable batteries. Avoid charging non-rechargeable batteries.
-
Safety Around Batteries: Exercise caution when working near lead-acid batteries due to explosive gasses and the risk of acid contact. Wear protective clothing and eye protection, and ensure proper ventilation.
-
Marine Unit Location: If installed in a marine environment, keep the unit away from the battery in a separate, ventilated compartment.
-
DC Connection Precautions: Connect and disconnect DC output connections only after switching off any marine unit switches and disconnecting the AC cord.
-
Compliance with Regulations: If in the USA, ensure that all external connections to the charger comply with the United States Coast Guard Electrical Regulations (33CFR183, SUB PART I).
-
Grounding Instructions: The unit should be connected to a grounded, metal, permanent wiring system or an equipment-grounding conductor.
Dedicated DC System: It’s not suitable for direct connection to a vehicle’s electrical system. Instead, it should be connected to a dedicated DC system with appropriate fusing and DC wiring gauge.
