WARNING
There is a risk of electric shock. Before you make electrical connections, disconnect the power supply.
CAUTION
Before you connect the supply power to the controller, complete the wiring and check all wiring connections. Short circuits or incorrectly connected wires can damage the controller and void any warranty.
CAUTION
Do not exceed the controller electrical ratings. If you exceed controller electrical ratings, it can result in permanent damage to the controller and void any warranty.
Important: Use copper conductors only. Wire in accordance with local, national, and regional regulations.
CAUTION
Electrostatic discharge can damage controller components. To avoid damaging the controller, use proper electrostatic discharge precautions during installation, setup, and servicing.
