Liebert AccuGuide®

High-PerformanceInterconnect Assemblies for

Systems with Parallel Surge Protection Devices

Interconnect made of conventional wire in conduit distributes line power, but reduces the performance of surge suppressors. The patented Liebert AccuGuide interconnect allows you

to get the most from your SPD by significantly reducing clamping voltages.

Liebert AccuGuide interconnect assemblies can maximize performance by transmitting transients generated by lightning and switching with minimal voltage drops. Each Liebert AccuGuide unit is an assembly of patented coaxial cables. (One Liebert AccuGuide coaxial cable is required for each protected mode.) Each cable minimizes inductance (through reduced coaxial aspect ratios), and features an extremely low impedance (2-10)unattainable in conventional interconnect. As a result, the assembly

delivers practically the entire surge to the Surge Protection Device (SPD). Clamping voltages are greatly reduced and system performance is improved.

Liebert AccuGuide is designed to aid any installation. This accessory is especially valuable in cases where the SPD cannot be installed close to the point of protection (greater than five feet). In conventional interconnect,

voltage loss increases with length — in excess of 16V/ft/kA for an ANSI/IEEE, C62.41 combinations wave. In contrast, Liebert AccuGuide losses are under 4.2V/ft/kA for an improvement of 400%.
