The Z4-Series Seismic Frame® Cabinet System features an industry-leading 1500 lb (680 kg) seismic equipment load with an additional 100 lb (45 kg) top load for cabling. It is UL Listed for its 3000 lb (1360 kg) static load and integrated grounding and bonding features.
Improving on CPI’s original Seismic Frame Cabinet, which was introduced in 2001, the Z4-Series Seismic Frame Cabinet delivers a higher load rating, an increased range of cabinet sizes to support deeper equipment and more unobstructed interior space along the sides for thermal and cable management accessories.
The Z4-Series Seismic Frame Cabinet was tested by a Telecommunications Carrier Group and ISO 17025 certified Independent Testing Laboratory (ITL) to meet Telcordia Technologies GR-63-CORE, Issue 4, April 2012, Sections 4.4 per Zone 4 requirements. GR-63-CORE seismic testing includes a series of physical shaker table tests during which a loaded cabinet is placed through simulated earthquake conditions. Zone 4 testing includes the most severe test conditions. The Seismic Frame Cabinet displayed limited movement and survived the test without permanent structural or mechanical damage, ensuring the internal equipment is not damaged.
