Important Notice:
- It is important to have a backup system in case of a system failure.
- Low-voltage and high-voltage wires must be passed through different conduits at
least 1 foot (30 cm) apart. If low-voltage and high-voltage conduits must be
crossed, the crossing must be at a 90-degree angle.
- All wiring must be made by a certified electrician and conform to local electrical
regulations.
