Separation Wall to Provide Intrinsic Safety (Ex ic)

To generate Ex ic rated spur outputs for Pepperl+Fuchs Segment Protectors in combination
with Fieldbus Power Supplies, a separation wall must be positioned inside the Segment
Protector. The separation wall is available as accessory. The separation wall is a mandatory
prerequisite to ensure the required clearance of 50 mm between the trunk terminals and the
spur terminals.
Danger!
Risk of explosion through insufficient type of protection
Using outputs with the insufficient type of protection can cause sparks or other hazards for
potentially explosive atmospheres that can ignite the surrounding atmosphere.
For the Segment Protector to generate intrinsically safe (Ex ic) outputs according to
IEC/EN 60079-11, use the specified accessories.
Accessory: ACC–R2–SW.3
Mounting the Separation Wall
1. Remove the T-connector.
2. Press the separation wall (ACC-R2-SW.3) into the gap of the T-connector.
