Surge Protection
For Business-Critical Continuity™
Liebert ® LM Series Surge Protective Device
Continuous Protection For Your Business
The Liebert LM Series:
The Most Advanced, Cost-Effective Product Line In The Industry
Standard Liebert LM Series (SPD)
The Liebert LM is a surge protective
device (SPD) that offers continuous
protection from damaging transients
and electrical line noise. The Liebert 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 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.
