Please observe the following wiring notes while performing wiring.
Wiring Notes
 To prevent electric shock, do not change wiring when the power is connected and has not
been turned off.
 Because there is no power switch on the HMI, ensure that an interrupter switch is attached on
its power cable.
 Please use shielded twisted-pair cables for wiring.
Recommended wiring is in the table below:

General Inspection

Periodically inspect the screws of the connection between the HMI and
device. Tighten screws as necessary as they may loosen due to vibration
and varying temperatures.
 Ensure that oil, water, metallic particles or any foreign objects do not fall
inside the HMI, control panel or ventilation slots and holes. As these will
cause damage.
 Ensure the correct installation and the control panel. It should be free
from airborne dust, harmful gases or liquids.
Inspection before
operation (power is
not applied)

Ensure that all wiring terminals are correctly insulated.
 Ensure that all wiring is correct or damage and or malfunction may result.
 Visually check to ensure that there are not any unused screws, metal
strips, any conductive or inflammable materials inside HMI.
 Ensure to lower electromagnetic interference when devices are influenced
by it.
 Ensure that the external applied voltage to HMI is correct and matched to
the controller.
Inspection before
operation (power is
applied)

Check if power LED lights.
 Check if the communication among devices is normal.
 Please contact our local distributors or Delta sales representative if there
are any abnormal conditions.
