INSTALLATION INSTRUCTIONS FOR THE
LIEBERT LM SERIES SURGE PROTECTIVE DEVICE
The Liebert LM Series Surge Protective Device is a high
quality, high energy surge current diversion system designed
to protect sensitive equipment from damaging transient
voltage surges. Proper installation is required for maximum
system performance.
UNPACKING AND INSTALLATION
Unpacking and Preliminary Inspection
1. Inspect the shipping crate(s) for damage or signs of
mishandling before unpacking the unit.
2. Remove any securing bands and cardboard packing
and inspect the unit for any obvious shipping damages.
3. If any damage as a result of shipping is observed,
immediately file a claim with the shipping agency and
forward a copy to your local Liebert Sales
Representative.
Handling Considerations
Larger units are bolted to a shipping pallet to facilitate
handling by forklift or pallet jack. Check the size and
weight. Refer to the cabinet data furnished with the unit.
Typical size and weights are referred to in Figure 1.
Storage
The unit should be stored in a clean, dry environment.
Storage temperature range is -55ºC (-67ºF) to +85ºC
(+185ºF). Care should be taken to avoid condensation. All
packing and shipping materials should be left intact until the
unit is ready for final installation. If the unit has been stored
for an extended period of time, the unit should be cleaned
and carefully inspected before placing into service.
Location Considerations
Environment – The unit is designed for operation indoors in
ambient temperatures of -40ºC (-40ºF) to +60ºC
(+140ºF) with a relative humidity of 0% to 95% (noncondensing).
The unit is provided in a metallic industrial enclosure,
which should not be installed in areas with excessive
dust, corrosive vapors, flammable materials or explosive
atmospheres.
The installer should perform the following steps to assure a
quality installation. The entire installation manual should be
read before starting installation. These instructions do not
replace national or local electrical codes. Check applicable
electrical codes to ensure compliance. Installation of the
Liebert LM Series Surge Protective Device should only be
performed by qualified personnel.
Audible Noise – The audible noise of the unit is less that 40
dBA at 5 feet, which allows its placement within almost
any room if desired.
Service Clearances – Service clearance is needed only at the
front of the unit. Thirty-six inches (36in / 914mm)
minimum is recommended.
Equipment Performance – For maximum system
performance, the unit must be located as close to the
protected circuit as practical to minimize interconnecting
wiring length.
For optimum transient surge protection, coordinated
surge suppression should be applied at the service
entrance and all other electrical connections to the
building (telephone, CATV, etc.), at known surge
generating loads within the building (large motors, arc
welders, switched capacitors, etc.), as well as at sensitive
electronic loads (such as computers, electronic
appliances, solid state motor drives, etc.). For
interconnected electronic loads (such as by way of data
cabling), transient surge suppression should also be
applied to the interconnecting wiring (data cables).
Mounting – Unit is intended to be wall mounted. Refer to
Figure 1 or unit submittal drawings for typical mounting
dimensions and weight.
Door Closing Adjustments
Single Door (Wall Mounted) – If the surface on which the
enclosure is mounted is not flat, the door may not open
and close properly. Also, if heavy equipment is
mounted on a large door, the door may sag slightly. If
the top of the door strikes the lip which extends around
the body opening, place metal shims behind the
mounting foot which is located at the bottom of the
enclosure and closest to the door hinge. Place the shims
between the mounting foot and the wall or mounting
surface. Be sure all mounting screws are tightened
securely.

ELECTRICAL CONNECTIONS
Suppression
Systems
All electrical connections should be installed by a qualified
(licensed) electrician only. All wiring must comply with the
National Electrical Code (NEC) and applicable local codes.
VERIFY THAT ALL POWER
CIRCUITS ARE DE-ENERGIZED AND
LOCKED OUT BEFORE MAKING
ELECTRICAL CONNECTIONS.
Voltage Ratings &
Power Source Configurations
Before making connections to the unit, verify that the unit
model number and nameplate voltage rating are appropriate
for connection to the intended power source. See Figure 2
for voltage rating applications with typical power source
configurations.
Surge Voltage Ratings – To obtain the suppression voltage
ratings (SVRs), as obtained by Underwriters Laboratory,
Incorporated, in accordance with the Standard for
Safety, Surge Protective Devices (SPDs), Standard 1449,
Second Edition, dated August 15, 1996, marked on this
product, #8 AWG wire must be utilized to connect the
LM series to your facilities’ power grid. Connections
made with conductors other that #8 AWG may result in
different SVRs.
Circuit Ampacity Limitations – This device has been
investigated by Underwriters Laboratories, Incorporated
to withstand, without exposing live circuits or
components on power sources, a voltage of two times
(2x) the device ratings, and fault currents of up to
300,000 AIC, as described in the Standard for Safety,
Surge Protective Devices (SPDs), Standard 1449,
Second Edition, dated August 15, 1996.
Parallel Connection (see Figures 3 and 4)
With parallel connection, the length of the wiring to the
surge protective device (SPD) unit must be minimized for
best performance. Wire lengths longer that 10 feet must be
avoided.
To reduce the wiring impedance to surge currents, the phase,
neutral (if required), and ground conductors are
recommended to be twisted together and routed in the same
raceway (conduit). Avoid any sharp bends in the conductors.
Wire Sizing – With parallel connection, the size of the
wiring to the SPD unit is independent of the protected
circuit’s ampacity. Suggested wire size of the product is
a number 8 gauge conductor minimum. Please reference
Figure 1. NEC Articles 280-21 and 22 require surge
arrestor connecting conductors to be at least #14 copper
or #12 aluminum.
Overcurrent Protection – The SPD unit conducts
practically no current under normal operation and only
conducts very short duration transient surge currents.
The Liebert SPD units contain UL approved internal
fusing to protect against device failure.
External overcurrent protection is not specifically
required by NEC Article 280 nor is it desired since it
impedes the performance of the surge protective device.
If fusing is required, please consult factory for
recommendations.
Disconnect Switch – SPD units must be connected to the
load side of the service disconnect, or load side of a
protected circuit’s disconnecting means. For best
performance, the SPD unit must be located very close to
the circuit to be protected and minimum interconnecting
wiring used.
A disconnect switch is sometimes used to facilitate
servicing the SPD unit. However, use of a disconnect
switch for the SPD unit impedes the transient surge
suppressing performance of the unit. For maximum
transient surge suppressor performance, no disconnect
switch is recommended. If a disconnect switch is used,
the location and wiring of the switch and SPD unit
should minimize the interconnecting wiring (see Figure
4).
Installation, Operation - 5 - LM Series
and Maintenance Manual Rev 0, 5/99
Models with a “R” suffix are equipped with an internal
disconnect switch, which can be used to de-energize the
unit’s transient surge suppressing components for
servicing.

System Grounding & Bonding
The performance and safety of any SPD system is dependent
on proper grounding and bonding. Grounding is required
primarily for safety. Correct implementation also enhances
equipment performance. Incorrect grounding can reduce or
impede the SPD’s operation.
All electrical circuits to or from the SPD must include an
equipment grounding conductor as required by the NEC and
local codes.
An insulated grounding conductor is recommended in
addition to any metallic raceway, which may be used as a
grounding conductor. For parallel-connected SPD, the
grounding conductor should be the same wire size as the
associated power conductors.
When metallic raceways are used, adequate electrical
continuity must be maintained at all raceway connections,
particularly raceway terminations to the electrical enclosures.
The use of isolating bushings or other means to interrupt
a metallic conduit run is a potential safety hazard and is
not recommended.
Grounding Electrode – Contrary to popular belief, surge
protective devices do not discharge all surges to ground
(earth). Surge protective devices divert the surge current
back to its source to complete the electrical circuit.
In the case of lightning whose potential is developed
with respect to the earth, the SPD diverts the surge
current to the grounding electrode (earth connection).
However, for most transient surges which are developed
by switching loads, the SPD diverts the surge current
back to its source without involving the grounding
electrode.
For proper SPD performance, the service entrance
grounding electrode system must comply with the
NEC by having all available electrodes (building
steel, metal water pipe, driven rods, concrete encased
electrodes, etc.) properly bonded together and
connected to the power system grounding.
The use of a separate grounding electrode to ground the
SPD defeats the effectiveness of the SPD, is a potential
safety hazard, may cause equipment damage, is an NEC
violation (reference NEC 250-51 and 250-54), and is not
recommended.

Liebert SPD Systems require little or no operator
intervention after installation.
The units are provided with diagnostic indicators and alarms
(optional) which assist in determining when the unit needs
service (see Troubleshooting/Repair/Maintenance Section).
Each active surge current diverter module is equipped with a
green and red LED. If the unit is energized and the green
LED is off (and/or the red LED is on), the surge current
diverter module is not fully functional and requires
replacement. See the maintenance section of this manual for
additional information.
System Monitor Panel – The unit may be equipped with
one or more of the following status indicators or alarms:
Summary Alarm Contact – Summary alarm Form C (1
N.O. and 1 N.C.) relay contacts are provided for remote
indication of each failed surge current diverter module/s.
For standard units (LED only), access to the summary
alarm contacts are provided via connection to the orange
and yellow 18 gauge conductors, located on the inside of
the panel (see Figure 1). For units with optional
accessories, access to the summary alarm contacts are
provided via contact terminals located on the printed
circuit board mounted on the inside of the unit’s door
(see Figure 1). Contacts are rated for 5 amps at 277
VAC maximum.
Transient Counter (optional) – A single transient counter is
provided for transient voltage surge monitoring. The
counter totalizes surges monitored since the last counter
reset.
The transient counter monitors line to ground transient
voltages. The circuit totalizes all surges that deviate
from the line sine wave envelope by more that 125 volts.
The counter is AC coupled and rejects transients longer
than 100 µs.

is luminated and the red “Service” LED is extinguished.
If one or more of the surge current diverter modules
requires replacement, the green “OK” LED is turned off
and the red “Service” LED illuminated.
Front Panel Counter Reset Disable / Enable Button
(provided on units with Transient Counters only) –
The counter is resettable from the counter reset switch.
The front reset may be disabled internally to provide
protection against tampering. To disable the front reset
follow the procedure below:
1) Remove power from the unit, lock out and tag the
disconnect or circuit breaker.
2) Open door and verify power is off with a voltmeter.
3) Throw SWXI on the power supply board to the
disable position.
Audible Alarm (optional) – If one or more of the surge
current diverter modules requires replacement, an
audible alarm is activated to draw attention to the fact
that repair service is required to restore the system to
normal operation. An audible alarm disable is provided
to silence the alarm. The system will automatically reset
itself after repair. The audible alarm switch and
“Service” LED can be tested by depressing the “Test”
switch on the system monitor panel.

Remote Monitor Panel (optional) – A remote monitor
panel is available to provide unit status and alarm
information at a location up to 500 feet away from the
LM Series Surge Protection System. Operation of the
Remote Monitor Panel is similar to the unit system
monitor panel. The “Enable” position of the switch is
the normal position, which allows audible alarm
operation. The “Disable” switch position silences the
audible alarm. The “Test” position tests the audible
alarm and indicator lights.
The remote monitor panel requires and external source
of power. Standard units are furnished with a six-foot
power cord with a NEMA 5-15 plug for connection to a
120 VAC source. Control connections are required from
the remote monitor panel to the power supply board in
the LM Series Surge Protection System. Connections
are made by way of two-conductor control cable fitted
with “RCA” plugs on one end (see Figure 5), which is
not furnished with the remote monitor panel.

status indication. If there are wires connected to this
terminal block, note each wires position so that they may
be correctly replaced on new power supply board.
Periodic system inspections, cleaning, and connection checks
are recommended to ensure reliable system performance and
continued surge transient protection.
It is difficult to establish a schedule for preventative
maintenance since conditions vary from site to site.
Inspections for failed surge current diverter modules using
available diagnostics should be done routinely (weekly or
monthly).

FIVE YEAR LIMITED WARRANTY AGAINST DEFECTS IN MATERIAL AND WORKMANSHIP

Terms of Warranty:
As provided herein, the Control Concepts product is warranted to be free of defects in material and workmanship for a period of five (5) years from the date of

that part.
Warranty Extends to First Purchaser for Use, Non-Transferable:
This Warranty is extended to the first person, firm, association or corporation for whom the Control Concepts product specified herein is originally installed for
use in the United States (the "User"). This Warranty is not transferable or assignable without the prior written permission of Control Concepts.
Assignment of Warranties:
Control Concepts assigns to User any warranties which are made by manufacturers and suppliers of components of the Control Concepts product and which are
assignable, but Control Concepts makes NO REPRESENTATIONS as to the effectiveness or extent of such warranties, assumes NO RESPONSIBILITY for any
matters which may be warranted by such manufacturers or suppliers and extends no coverage under this warranty to such components.
Descriptions:
Control Concepts warrants for the period and on the terms of the Warranty set forth herein that the Control Concepts product will conform to the descriptions
contained in Control Concepts' final invoices, orders and Control Concepts' product brochures. Control Concepts does not control the installation and use of any
Control Concepts product. Accordingly, it is understood that the Descriptions are NOT WARRANTIES OF PERFORMANCE and NOT WARRANTIES OF

Obtaining Performance Under This Warranty:
Within a reasonable time, but in no case to exceed thirty (30) days, after User's discovery of a defect, User shall contact Control Concepts and request a return
authorization number. User shall ship the product, with proof of purchase, to Control Concepts freight prepaid. Control Concepts products shipped to Control
Concepts without a return authorization number will be refused and returned freight collect to User at User's expense. Control Concepts products shipped by User

treatment or use which would void the coverage of this Warranty.
