observe the following precautions:
 Install the product in a clean and dry location free from corrosive and inflammable gases or liquids.
 Ensure that all wiring instructions and recommendations are followed.
 Ensure that HMI is correctly connected to a ground. The grounding method must comply with the
electrical standard of the country (Please refer to NFPA 70: National Electrical Code, 2005 Ed.).
 Do not disassemble HMI, modify or remove wiring when power is applied to HMI.
 Do not touch the power supply during operation. Otherwise, it may cause electric shock.
If you have any questions during operation, please contact our local distributors or Delta sales
representatives.

(2) Safety Precautions

Carefully note and observe the following safety precautions when receiving, inspecting, installing,
operating, maintaining and troubleshooting. The following words, DANGER, WARNING and STOP are
used to mark safety precautions when using the Delta's HMI product. Failure to observe these
precautions may void the warranty!
Installation
Comply with quick start for installation. Otherwise it may cause equipment damage.

 Do not install the product in a location that is outside the stated specification for the HMI.
Failure to observe this caution may result in electric shock, fire, or explosion.
Do not install the product in a location where temperatures will exceed specification for

the HMI. Failure to observe this caution may result in abnormal operation or damage the
product.
Please note that this equipment has obtained EMC registration for commercial use. In the

event that it has been mistakenly sold or purchased, please exchange it for equipment
certified for home use.
Do not use this product as an alarm device for disaster early warning that may result in

personal injury, equipment damage, or system emergency stop.
Wiring
Connect the ground terminals to a class-3 ground (Ground resistance should not exceed

100Ω). Improper grounding may result in communication error, electric shock or fire.
Operation
The users should use Delta editing software, DOPSoft to perform editing in Delta's HMI

product. To perform editing and confirming HMI programs without using Delta editing
software, DOPSoft in Delta's HMI product may result in abnormal operation.
To prevent the personal injury and equipment damage, when designing HMI programs,

please ensure that a communication error occurred between Delta's HMI product and the
connecting controller or equipment will not result in system failure or malfunction.
Please be sure to backup the screen data and HMI programs in case they are lost,

accidentally deleted or worse.
Do not modify wiring during operation. Otherwise it may result in electric shock or

personal injury.
 Never use a hard or pointed object to hit or strike the screen as doing this may damage
the screen and let the screen has not respond at all, and then cause HMI to work
abnormally.
Maintenance and Inspection
 Do not touch any internal or exposed parts of the HMI as electrical shock may result.
Do not remove operation panel while power is on. Otherwise electrical shock may result.

Wait at least 10 minutes after power has been removed before touching any HMI

terminals or performing any wiring and/or inspection as an electrical charge may still
remain in the HMI with hazardous voltages even after power has been removed.
Turn the power off before changing backup battery and check system settings after

finishing change. (all data will be cleared after changing battery).
Be sure the ventilation holes are not obstructed during operation. Otherwise malfunction

may result due to bad ventilation or overheating troubles.
Wiring Method
 Do not use a voltage that will exceed specification for the HMI. Failure to observe this
caution may result in electric shock or fire.
Remove the terminal block from the HMI before wiring.

 Insert only one wire into one terminal on the terminal block.
If the wiring is in error, perform the wiring again with proper tools. Never use force to

remove the terminals or wires. Otherwise, it may result in malfunction or damage.

Communication Wiring

Comply with communication wiring specification for wiring.

 Wiring length should comply with the stated specification for the HMI.
Proper grounding to avoid bad communication quality.

To avoid noise and interference, the communication cable, all power cables, and motor

power cable should be placed in separate conduits.
