Product Usage Instructions
Installation
When installing the EB3C-N Relay Barrier, ensure it conforms to the provided
drawings and descriptions as well as all relevant requirements.
Location
The Barrier must be placed in a safe area (non-hazardous area). Intrinsically
safe apparatus can be located in the hazardous area.
Maintenance
Defective Barriers should be returned to the factory for repair. Avoid
unauthorized repairs or component substitutions.
Connection
The Signal input terminal (Pn-Nn) should only be connected to intrinsically
safe circuits with proper isolation to the hazardous area.
Mounting
Mount the Barrier on a 35mm track or directly on a panel surface using screws.
Ensure all fastening means are properly tightened and secured.
Certification Information
Certified Barrier types are classified based on output, channels, signal type,
power supply, and connection type.
Type EB3C-N Relay Barrier
For Intrinsically Safe System II(1)G [Ex ia Ga]IIC, II(1)D [Ex ia Da]IIIC
INTRODUCTION
When installing an IDEC Type EB3C-N Relay Barrier (thereafter, called
Barrier), make sure it conforms to the following drawings and descriptions as
well as all applicable requirements.
EN IEC 60079-0:2018, EN 60079-11:2012, EN 60079-25:2010, EN 60079-14:2014
All intrinsically safe systems must have “EB3C-N” in the part number. Barrier
must be located in a safe area (non-hazardous area).
The intrinsically safe apparatus, such as the Contact certificated, approved
or considered to be a “simple apparatus” such as the Switch specified by
standard, may be located in the hazardous area.
- Servicing – Replacement and Repairs: Inspection and replacement of Barrier shall not be made until power is disconnected and shall not be connected again until all replacement Barrier are properly re-assembled. All electrical components, including the interconnecting wiring, shall be kept in safe condition. Defective Barrier should be returned to the factory for repair.
Warning ! Substitution of components or unauthorized repair may impair
intrinsic safety of apparatus.
To maintain intrinsic safety, the Signal input terminal (Pn-Nn) may only be
connected to intrinsically safe circuits where both the wiring and the
connected equipment maintain 500 V isolation to the hazardous area
earthing/bonding connections.
Mounting: All bolts, nuts, screws, and other means of fastening, including the unused wiring screws, shall be fastened in place,properly tightened and secured. Mount Barrier on a 35mm track or directly mount on a panel surface using screws.

Rating and Parameters of I.S
Ta= 60C, Um= 250V, Uo=13.2V, Io= 14.2mA, Po= 46.9mW at each channel Pn-Nn, Io=227.2mA, Po= 750mW at max 16 channels Pn-Nn
Typical Installation
Install Barrier must be according to the above Ratings and Parameters of I.S. and descriptions.
To avoid electrical shock, install Barrier in a tool-accessible enclosure. Layout and wiring must be done to prevent the inductive or capacitive induction to the intrinsically safe circuit. For example, separate intrinsically safe circuits from non-intrinsically safe circuits, by a minimum space of 50mm or using a full height metal separator. If color-coding is required use for the intrinsic safe components and terminals, use only cables and terminals with light blue markings. Interconnection between the Barriers to setting Common Wiring: connect two independent wires in parallel at each two “ N “ terminals between adjacent the Barrier inside the panel. Maintain at least 3 mm clearance between the external connection terminals and the grounded metal part.
Dielectric Strength: Between intrinsically safe circuit and non- intrinsically safe circuit 1526.4V AC.
Example of connections: The marks indicate the samples of single intrinsic safe circuits, and marks indicate IS apparatus.
Common Wiring (e.g. Io=227.2mA with 16 channels)
Separate Wiring (e.g. Io=14.2mA with 1 channel)
