CSA Hazardous Area Approvals Fisher™ FIELDVUE™ DLC3020f Digital Level Controller for FOUNDATION™ Fieldbus
Hazardous Area Classifications and Special Instructions for “Safe Use” and Installations in Hazardous Locations Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may override, the standard installation procedures. Special instructions are listed by approval.
Note This information supplements the nameplate markings affixed to the product and the DLC3020f quick start guide (D103470X012) and instruction manual (D103434X012), available from your Emerson sales office or Fisher.com. Always refer to the nameplate itself to identify the appropriate certification.
WARNING Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion, or area re‐classification.

Frequently Asked Questions
What risk should be considered if I fail to follow the 'safe use' conditions?
Failure could result in personal injury or property damage from fire, explosion, or area re‐classification.
What are the required electrical parameters for interconnection using the Entity Concept?
The originating apparatus’s voltage (V_max), current (I_max), and power (P_max) must be equal to or greater than those defined by the associated apparatus, along with specific capacitance/inductance limits.
What codes mandate adherence during DLC3020f installation?
Installation must comply with the Canadian Electrical Code (CEC) Part 1 and ANSI/ISA RP12.6.
What are the electrical details for the RTD terminals in a hazardous location setting?
The specified parameters are V_oc = 6.6 VDC, V_max = 24 VDC, I_sc = 29.5 mA, I_max = 380 mA, and Po = 49 mW.
