CAUTION:
a cable lug to the grounding and power cables that you supply. A cable with an
incorrectly attached lug can damage the device (for example, by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the device to earth ground before you connect
them to power. For installations that require a separate grounding conductor to the
device, use the protective earthing terminal on the device to connect to the earth
ground. For instructions on connecting earth ground, see
to an NFX350 Device" on page
NOTE:
Grounding is required for DC systems and recommended for AC systems. An AC-powered
device gets additional grounding when you plug the power supply in the device into a grounded
AC power outlet by using the AC power cord appropriate for your geographical location.
Ensure that you have the following parts and tools available:
DC power source cables (14 AWG) with ring lug (Molex 0190700067 or equivalent) (not provided)
attached to them by a licensed electrician
Phillips (+) screwdriver, number 2
