Instruction Sheet 
(1) General precautions 
Thank you for purchasing this product. This instruction sheet provides information about the DOP-100 
series HMI. Before using this product, please read through this instruction sheet carefully to ensure the 
correct use of the product. Please keep this sheet handy for quick reference whenever needed. Before 
finishing reading this sheet, please follow the instructions below: 
 Install the product in an indoor location, which is free of vapor, corrosive and inflammable gas and 
liquids. 
 Please refer to the wiring diagram when connecting the wires.  
 Ensure your HMI is correctly grounded. The grounding method must comply with the national 
electrical standard (please refer to NFPA 70: National Electrical Code, 2005 Ed.). 
 Do not disassemble the HMI or change the wiring when power is on.  
 Do not touch the power supply when power is on, or it may cause electric shock.  
 When the HMI displays a low power notification and requires a battery change, please contact 
your local distributor or Delta Customer Service Center for the replacement. Do not change the 
batteries by yourself. 
 This product can be used with other industrial automation equipment. Please read through this 
sheet carefully and install the product according to the instructions to avoid danger. 
 Cleaning method: please use a dry cloth to clean the product.  
 This product must be used at an altitude below 2,000 m.  
 If the equipment is used in a manner not specified by the manufacturer, the protection provided by 
the equipment may be impaired.

A Operation / display area 
Precautions: 
 Incorrect installation may result in malfunction.  
 To ensure the HMI is well ventilated, make sure there is sufficient space between the HMI and the 
adjacent objects or walls.  
 This product should be used on a case / platform which conforms to enclosure Type 4X standard (for 
indoor use only). 
 The maximum panel thickness for mounting must be no greater than 5 mm. 
Installation steps: 
Step 1: 
Put the waterproof gasket into the HMI and then 
insert the HMI into the panel cutout. 
Step 3: 
Tighten the screws with the torque less than  
0.5 N-M / 0.7 N-M to avoid damage to the plastic 
case.  
DOP-103BQ torque: 4.41 lb-inch (0.5 N-M) 
Step 2: 
Place the fasteners into the slots and tighten the 
screws until reaching the panel cutouts. 
Step 4: 
For heat dissipation, please keep a minimum 
clearance of 60 mm on the rear of the HMI.

Note: 
1. The half-life of the backlight is defined as the maximum luminance being reduced by 50% when the 
maximum drive current is supplied to the HMI. The life of LED backlight shown here is estimated at the 
room temperature of 25
2. The withstand voltage of the isolated power circuit is 1500V peak for 1 minute.  
3. The HMI power consumption is the power consumed when the HMI is not connecting with other 
peripheral devices. To ensure normal operation of the HMI, the recommended capacity of the power 
supply is 1.5 to 2 times of the specified power consumption. 
4. Isolated power supply is recommended.
