Grounding - Panasonic ELC500 User Manual

3.2.3

Grounding

■In case of excess noise
Under normal conditions, the inherent noise resistance is sufficient. However, in case of that it is used
under the excess noise, ground the unit to increase noise suppression.
■Exclusive grounding
・When supplying 24V DC directly to ELC500, ground the function earth (green).
・For grounding purposes, use wire with the cross section of 1.25mm
less than 100Ω.
・The grounding point should be as close to ELC1 as possible. And the grounding wire should be as
short as possible.
・If the ground point shares with the other device, it may occur an adverse effect. Always use an
exclusive ground for each device.
