Considerations; Grounding The Device - Advantech EKI-7712 Series User Manual

2.7.2

Considerations

Take into consideration the following guidelines before wiring the device:
The Terminal Block (CN1) is suitable for 12-24 AWG (3.31 - 0.205 mm

value 7 lb-in.
The cross sectional area of the earthing conductors shall be at least 3.31 mm

Calculate the maximum possible current for each power and common wire.

Make sure the power draw is within limits of local electrical code regulations.
For best practices, route wiring for power and devices on separate paths.

Do not bundle together wiring with similar electrical characteristics.

Make sure to separate input and output wiring.

Label all wiring and cabling to the various devices for more effective manage-

ment and servicing.
Note!
Routing communications and power wiring through the same conduit
may cause signal interference. To avoid interference and signal degra-
dation, route power and communications wires through separate con-
duits.
2.7.3

Grounding the Device

Caution! Do not disconnect modules or cabling unless the power is first switched
off.
The device only supports the voltage outlined in the type plate. Do not
use any other power components except those specifically designated
for the switch device.
Caution! Before connecting the device properly ground the device. Lack of a
proper grounding setup may result in a safety risk and could be hazard-
ous.
Caution! Do not service equipment or cables during periods of lightning activity.
Caution! Do not service any components unless qualified and authorized to do
so.
