Introduction
Thank you for purchasing an MDI Intrinsically Safe Modbus Network Display and Controller from APG. We
appreciate your business! Please take a few minutes to familiarize yourself with your MDI and this manual.
The MDI Intrinsically Safe Modbus Network Display and Controller provides a local display in a Class I, Zone
1 area that can monitor and control a sensor within a Class I, Zone 0 or Class I , Zone 1 hazardous area. The
MDI can supply power to the sensor it controls, creating a complete monitoring-and-control system within
the hazardous area. The MDI can also be connected to monitoring equipment outside the hazardous area
through an IS barrier, allowing readings from the sensor to be seen across a montioring or control network.
The MDI features a large 5-digit display, IP66-rated housing options, and user selectable units of measure.
Reading your label
Every APG instrument comes with a label that includes the instrument’s model number, part number, serial
number, and a wiring/pinout table. Please ensure that the part number and pinout table on your label
match your order. The following electrical ratings and approvals are also listed on the label. Please refer to
the Certicate of Compliance at the back of this manual for further details.

Chapter 2: Installation and Removal Procedures and Notes
Installing the MDI requires tools appropriate to the fasteners being used (screw driver, socket driver, etc.).
• Tools Needed
• Mounting Instructions
Specic mounting steps may vary based on mounting methods being used.
A general approach is as follows:
• Use fasteners through 7mm holes on either side of housing for surface mounting of MDI.
• For conduit mounting, make electrical connections (see Electrical Installation, below) prior to nal con-
duit connections.
The MDI should be installed in an area--indoors or outdoors--which meets the following conditions:
• Ambient temperature between -30°C and 85°C (-22°F to +185°F)
• Relative humidity up to 100%
• Altitude up to 2000 meters (6560 feet)
• IEC-664-1 Conductive Pollution Degree 1 or 2
• IEC 61010-1 Measurement Category II
• No chemicals corrosive to stainless steel (such as NH3, SO2, Cl2etc.) or aluminum
• Ample space for maintenance and inspection
• Physical Installation Notes
IMPORTANT: Your MDI MUST be installed according to drawing 9005447 (Intrinsical-
ly Safe Installation Drawing For Hazardous Locations) as indicated above to meet listed
approvals. Faulty installation will invalidate all safety approvals and ratings.
• Install per Document #9005447.
• Use only three-SAFT model LS14500 or three-Xeno model XL-060F battery cells.
• Do not replace batteries when an explosive atmosphere is present.
• The enclosure is manufactured from aluminum. In rare cases, ignition sources due to impact and
friction could occur. This shall be considered during installtion.
