When installing an IDEC Type EB3L-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 “EB3L-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 output 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.
• Certified Barrier: Type EB3L-abcdeN “EB3L-…N”= Series type

a = Output          S: for Supper LED   b = channels    01, 02, 03, 05, 06, 08, 08C, 10, 16C ( C: common wiring only)
c = Signal type    K: Sink, S: Source    d = Power supply    A: 100~240Vac, D: 24Vdc    e = connection   Blank: Terminal, -C: Connector

• Rating and Parameters of I.S.

Ta= 60°C, 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)
