3. Verify that the resistance of the ground path is less than 0.5 ohms.
Installing the SmartNode 4740
To prevent overheating and damaging the unit, proper ventilation
is required when placing the device; leave at least 2 inches (5
cm) to the left, right, front, and rear of the SmartNode device.
The device should be installed in a dry environment with suffi-
cient space to allow air circulation for cooling. Do not stack multi-
ple SmartNode devices directly on top of one another, and do not
place items on top of the device. If you will be installing equip-
ment above the SmartNode device, leave at least 2 inches (5
cm) of clearance between the devices.
Do not work on the system or connect or disconnect
cables during periods of lightning activity.
The Interconnecting cables shall be acceptable for external
use and shall be rated for the proper application with
respect to voltage, current, anticipated temperature, flam-
mability, and mechanical serviceability.
According to UL60950/IEC62368, a connection to earth
