AC mains connection

• The Hub must be connected to an isolation device and current interruption device rated at no greater than 6A
  • This connection must only be made by a competent person and must comply with the relevant national and local electrical codes
  • This connection must be made to the AC mains connection terminals (Figure 1 and Figure 2). Do not connect AC mains to any other terminals
• All other terminals and wiring inside the enclosure are safety extra low voltage (SELV) and the AC wiring must be kept physically separated from them. The AC wiring must not share an enclosure aperture with any other wiring. If not using a conduit, fit a cable gland to the selected aperture to secure the AC wiring in place and protect it from damage
• The Hub enclosure must be connected to mains earth using the terminal block provided
• For compliance with electrical codes, the cable must use conductors of minimum 2.5mm2 or, if using a a non-flexible metal conduit, the conductors must be a minimum of 1.5mm2

Battery connection

Optional backup power can be provided using a 12V sealed lead acid battery. Only use a 12V battery approved to IEC 60896 and rated for a charging current up to 1.7A and a load current up to 8A

<aside> 💡

Accessia recommends using Yuasa model NP12-12G which has a rated capacity of 12Ah

Connect the battery to the Hub using the labeled terminals and the wires supplied

• The red wire is positive and the black wire is negative
• The supplied wires include a thermistor for monitoring the battery temperature
• Make sure to place the battery securely in the base of the enclosure with the terminals facing upwards
