POWER SUPPLY module MA

The power supply must be connected to Terminals 1 and 7. The characteristics of the power supply are shown on the side label.

WARNING.- If the power supply is dc voltage, be careful with the polarity indicated for each terminal.

Make sure the signal conditioner is correctly connected to a power supply of the correct voltage and frequency. Do not use any other power supply. Permanent damage may result to the signal conditioner.

PRECAUTIONS.- The installation must incorporate safety devices to protect the operator and the process when using the signal conditioner to control a machine or process where injury to personnel or damage to equipment or process, may occur as a result of failure of the signal conditioner.
