5. g polarity on the load terminals Never connect loads in this situation REMARK Keep in mind the recommendations of your battery manufacturer We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the battery wiring The fuse type must be in accordance with the charge controller s nominal current CA06 CAO8 2 1 20A CA10 2 1 CA14 1 1 30A 17 Connect the wires leading to the solar array with correct polarity To avoid any voltage on the wires first connect the controller then the solar array Keep in mind the recommended wire size CA06 2 1 min 2 5mm CA08 2 1 min 4mm CA10 2 1 min 6mm CA14 1 1 min 10mm REMARK place positive and negative wires leading to the solar generator close to each other to minimize electromagnetic effects REMARK Solar panels provide voltage as soon as exposed to sun light Keep in mind the solar panel manufacturers recommendations in any case Connect the wires leading to the loads with correct polarity To avoid any voltage on the wires first connect the wire to the load then to the controller Keep in mind the recommended wire size CA06 2 1 min 2 5mm CA08 2 1 min 4mm CA10 2 1 min 6mm CA14 1 1 min 10mm 18 Grounding the Solar System Be aware that the positive terminals of the controller are connected internally and therefore have the same electrical potential If any
6. nstall it in humid rooms like bathrooms The controller measures the ambient temperature to determine the charging voltage Controller and battery must be installed in the same room The controller warms up during operation and should therefore be installed on a non flammable surface only REMARK Connect the controller by following the steps described below to avoid installation faults T When mounting the controller with screws make sure to use screws that suit the attachment material use screws with 4 mm shaft and max 8 mm head diameter no counter sink Keep in mind that the screws also have to carry the force applied by the wiring Make sure that the ventilator slits on the sides are unobstructed 16 A DIN Rail mounting plate is available as an accessory CX DR2 This allows mounting the controller on a standard 35mm DIN rail Place the controller on the mounting plate and use the screws supplied with the mounting plate to fix it to the controller Connect the wires leading to the battery with correct polarity To avoid any voltage on the wires first connect the controller then the battery Keep in mind the recommended wire length min 30 to max approx 100 cm and the wire size CA06 2 1 min 2 5mm CA08 2 1 min 4mm E CA10 2 1 min 6mm CA14 1 1 min 10mm WARNING If the battery is connected with reverse polarity the charge controller will also give the wron
