Installation Guidelines (Field Engineer Notes)

Power Selection: Activate SW1 external to use an external 24V DC power supply. If backplane power is sufficient, use backplane power instead of external supply.

Wiring: Use 14 AWG maximum wire size. Limit to 2 wires per terminal. Use shielded cable for analog signals. Ground shield at the module end only.

Slot Selection: Install away from AC or high DC voltage sources. Install away from system power supply. Preferred chassis is nearest to enclosure bottom for thermal considerations.

Load Connection: Maximum load reactance is 1 µF. Maximum load current is 10 mA. Verify load compatibility before connection.

Power Removal: Do not remove module under power. Electrical arcs may damage electronic circuitry.
