supplied cable
• Only one earth ground connection is required on
the LIB-400 at either TB1 or TB2.
• Silkscreen markings on TB2 of the LIB400 vary from
the above illustration: twos instead of ones are used,
so the markings are +L2A, -L2A, +L2B, and -L2B.

Surge Suppression

There are three (3) primary surge protectors that are approved for use with this FACP.
• DTK-2LVLP-F
• SLCP-030

Note: For detailed information refer to the installation documentation that was supplied with the unit.
One primary surge protector must be used with each SLC wiring pair whenever SLC wiring runs outside the building.
• Install primary protection only as shown in this document.
• Refer to NEC Article 800 and local building code requirements.
Additional primary surge suppressors maybe added as required by the NEC. Add these additional
suppressors in series with the SLC wiring at the building entry/exit.
Wiring connected to the surge suppressor output must remain within the building while wiring connected to
the surge suppressor input may be routed outside the building as shown in "Building Entry/Exit Connections"
in Figure 4.2-3.

Suppressor Installation
