MultiPlus-II 2x120V 4.2. Vibration management CAUTION When integrating inverter/chargers with generators in a single enclosure (hybrid generators), using shock mounts is mandatory. They mitigate damage risk to the inverter/charger by absorbing the generator's operational energy, thus extending component lifespan. Key criteria for selecting shock mounts include: Selection is based on the specific generator vibration frequency ranges to be isolated. The shock mounts must bear the equipment's weight without impairing functionality. 4.3.
Connection of battery cables To fully utilize the product's capacity, ensure the use of batteries with adequate capacity, an appropriate DC fuse, and battery cables of sufficient cross-section. DC cables should be copper, with a 90єC (194єF) rating. Refer to the table below for sizing recommendations. In Canada, battery installation should be in accordance with the storage battery rules of the Canadian Electrical Code, Part I. * Follow local installation rules. ** Do not locate battery cables in a closed conduit *** “2x” means two positive and two negative cables. Connection procedure Use a torque wrench with an insulated box spanner in order to avoid shorting the battery.
Recommended torque: 12 Nm (M8 nut) Avoid shorting the battery cables. Proceed as follows to connect the battery cables: Undo the two screws at the bottom of the enclosure and remove the service panel Connect the battery cables: see A: Connection overview [28] . The connector goes on first, followed by the flat washer, lock washer, and nut. Tighten the nuts well for minimal contact resistance. Tighten the nuts well for minimal contact resistance. Internal resistance is an important factor when working with low-capacity batteries. Please consult your supplier or the relevant sections of our Energy Unlimited or Wiring Unlimited books. Both can be downloaded from our website.
