1. Precautions Regarding Installation
When installing the equipment and performing the instrumentation work, take due care of the following
precautions.
1. When performing the grounding work, connect the ground wire to the ground terminal inside the panel.
Use wire with a diameter equal to or larger than the power supply wire (AWG-14).
2. Do not install an overcurrent circuit breaker in the grounding wire.
3. Install a ground fault circuit breaker with over-current protection or independent devices to protect against
short circuits, overloads, and grounds faults within 10 ft (3 m) of the node point in the low-voltage interior
wiring.

4. Use a power supply wire with insulation resistance of 0.1 MΩ or higher.
5. Use AWG-14 or larger diameter for the power line. Protect the wire in a conduit.
6. Use a 100 m (330 ft) or shorter Cat 5 cables to connect equipment
7. Install power supply wires and communication wires separately.
