The LM utilizes patented circuitry to monitor the status of all protection modes, including neutral to ground. Should protection be unavailable in any mode, the green LED will be extinguished, and the red LED will be illuminated. In addition, high isolation form C dry contacts provide for remote monitoring of suppression system failure, under voltage, and phase and power loss. LM patented suppression integrity monitoring indicates failure for both shorted or opened suppression components. Standard LM Series SPD The LM Series can be a facility-wide product family and may be installed from service entrances to distribution panels to branch panels. ¦ Commercial buildings ¦ Institutional facilities ¦ Industrial plants ¦ Any facility that has an environment with electronics-based equipment At A Glance ¦ Modular design allows for flexibility ¦ Surge suppression range up to 500 kA per phase ¦ Industry’s highest surge current repeatability ¦ Internal/external monitoring, including neutral to ground ¦ UL rated 200k AIC with component level fusing for safe operation ¦ All modes of protection standard, any combination optional ¦ Sine wave tracking, EMI/RFI filtering ¦ UL 1449 (second edition), UL1283 and CUL listed ¦ ANSI/IEEE C62.11, C62.41, C62.45 categories A, B, and C3 tested ¦ Tested to NEMA LS1 ¦ NEMA 12 enclosure with 3R, 4, and 4X options available ¦ 5-year warranty ¦ 2 sets of Form C dry contacts ¦ Audible alarm ¦ Choice of options ¦ Disconnect ¦ Transient counter ¦ Remote monitor panel ¦ Test set 2 Standard Features Optional Features Unit Status Indicators The unit has an integral status circuit that monitors the operational status of all modes of protection, including Line to Neutral, Line to Ground, and Neutral to Ground. In the unlikely event that protection is reduced, the green LED will go out and the red LED will be lit. LED indication shall be provided internal and external to the product. Enclosure The unit is housed in a heavy duty, steel, NEMA 12 dust-tight, drip-tight enclosure. Undervoltage Detection System monitoring will indicate an undervoltage at 70% of nominal. Phase and Power Loss Monitoring System monitoring will indicate a loss of any phase or loss of power. Noise Attentuation The filter provides insertion loss up to 60 dB from 100 kHz to 100 MHz per 50 Ohm Insertion Loss Methodology from MIL Std. 220A. Overcurrent Protection All components are individually fused and unit is UL rated for 200k AIC for safe operation. Audible Alarm The system is equipped with an audible alarm activated when summary alarm contacts are activated. An ON/OFF button is provided to silence the alarm, and an alarm push-to-test button to test the alarm function. A visible LED confirms whether alarm is on or disabled. Both buttons and the audible alarm are located on the panel’s front cover. Agency Listing The specified unit is UL 1449 (Second Edition) Listed, UL 1283 Listed, and CUL Listed. Control Concepts/Liebert is also company certified ISO 9001 for manufacturing, design, and service. Warranty A full five-year parts warranty. Form C Dry Contacts Two sets of electronically isolated form C dry contacts are provided, (two normally open, two normally closed) for remote monitoring. Life Cycle Testing The system is life cycle tested to survive multiple 10kA, 20KV, IEEE C62.41 Category C3 transients with less than 5% degradation of clamping voltage. The minimum numbers of surges the unit shall be able to protect against are 8,000 per phase. Integral Fused Disconnect A 200k AIC integral disconnect switch located within the system enclosure with an external manual operator. Transient Counter The system can be equipped with a transient counter which totals transient surges that deviate from the sine wave envelop by more than 125 volts. The counter is located on the unit's front cover and features an 8 digit LCD, lithium batteries (with 10-year life), and reset switches. Remote Monitor Panel A self contained, UL Listed monitoring panel. Input power to the monitoring panel is equipped with a 6-foot power cord with a 3 NEMA 5-15 plug. The monitor has an audible alarm, red and green LEDs silence switch, and a test switch. 3 Specifications LM Series Surge Suppression Life Cycle Surge Testing 10kA, 20kV, IEEE, Cat.
