IDEC EB3L Relay Barrier (alias Lamp Barrier) Installation
Type EB3L-N Relay Barrier (alias Lamp Barrier)
For Intrinsically Safe System II(1)G [Exia]IIC, II(1)D [Exia]IIIC
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 60079-0, EN 60079-11, EN 60079-25, EN 60079-14
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 the 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. The defective Barrier should be returned to the factory for repair.
Warning! Substitution of components or unauthorized repair may impair the intrinsic safety of apparatus. -
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.

*: Therefore, the values are allowable only at Li < 1%Lo and Ci < 1%Co of the intrinsic safe apparatus.
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.
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)
