INSTALLATION INSTRUCTIONS

The Liebert Surge Protective Devices (SPDs) are high quality, high energy surge current diversion systems 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 ﬁ le 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.

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 ﬁ nal 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% (non-condensing).

The unit is provided in an industrial use enclosure, which is dust-tight and drip-tight and should not be installed in areas with excessive dust, corrosive vapors, ﬂ ammable materials or explosive atmospheres.

Audible Noise — The audible noise of the unit is less than 40 dB at 5 feet, which allows its placement within almost any room if desired.

Service Clearances — Service clearance is needed for units with hinged doors on the front that are capable of being opened. Thirty-six inches (36 in/914 mm) minimum is recommended.

Surge Suppression Systems

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 SPD system should only be performed by qualiﬁ ed personnel.

EQUIPMENT PERFORMANCE!!

To maximize system performance locate unit as close as possible to protected circuit and keep inter connecting wiring less than 5 ft.

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 individual instruction sheet or unit submittal drawings for typical mounting dimensions and weight.

ELECTRICAL CONNECTIONS

Surge Suppression Systems

All electrical connections should be installed by a qualiﬁ ed (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 and Power Source Conﬁ gurations

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 the chart on page 4 for voltage rating applications with typical power source conﬁ gurations.

Parallel Connection (see Figures on page 5)

EQUIPMENT PERFORMANCE!!

For maximum system performance, the unit must be located as close to the protected circuit as practical to minimize interconnecting wiring length.

To reduce the wiring impedance to surge currents, it is recommended that the phase, neutral (if required), and ground conductors are 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. For suggested wire size refer to individual product sheet.

NEC Article 285-21(B) requires surge suppressor 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 following is from the National Electric Code 2002 Edition.

285.21 Connection. Where a TVSS is installed, it shall be connected as follows:

(A) Location.

(1) Service Supplied Building or Structure. The transient

voltage surge suppressor shall be connected on the load side of a service disconnect overcurrent device required in 230.91.

(2) Feeder Supplied Building or Structure. The transient

voltage surge suppressor shall be connected on the load side of the ﬁ rst overcurrent device at the building or structure.

Exception to (1) and (2): Where the TVSS is also listed as a surge arrestor, the connection shall be as permitted by Article 280.

(3) Separately Derived System. The TVSS shall be

connected on the load side of the ﬁ rst overcurrent device in a separately derived system.

Disconnect Switch (If Provided) — All SPD units must still be connected to the load side of the main service disconnect, or load side of a protected circuit’s disconnecting means.

Surge Voltage Ratings — To obtain the suppression voltage ratings (SVRs), as obtained by Underwriters Laboratory, Incorporated, in accordance with the Standard for Safety, Transient Voltage Surge Suppressors (TVSS), Standard 1449, Second Edition, dated August 15, 1996, marked on this product, the wire size listed for each product must be utilized to connect the unit to your facilities’ power grid. Connections made with conductors other than the wire size listed may result in different SVRs.

Circuit Ampacity Limitations — Representative samples of these products have been investigated by Underwriters Laboratories, Incorporated to withstand, without exposing live circuits or components at system voltages and fault currents ranging from 14,000 AIC up to 200,000 AIC, as described in the Standard for Safety, Transient Voltage Surge Suppressor (TVSS), Standard 1449, Second Edition, dated August 15, 1996. Verify each products fault current rating on the individual installation pages that follow.

System Grounding and Bonding

The performance and safety of any SPD system is dependent on proper grounding and bonding. Grounding is required for safety. Correct implementation also enhances equipment performance. Incorrect grounding can reduce or impede the SPD’s operation.

All electrical circuits to the SPD must include an equipmentgrounding conductor as required by the NEC and local codes.

An insulated grounding conductor is required in addition to any metallic raceway, which may be used as a grounding conductor. For parallel-connected SPDs, the grounding conductor should be the same wire size as the associated power conductors. Grounding conductors must be routed with the associated power conductors in the same raceway (conduit).

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 — 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 that 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.

Surge Suppression Systems

FOR PROPER AND SAFE OPERATION, THE NEUTRAL, (IF PROVIDED), MUST BE RELIABLY CONNECTED TO THE NEUTRAL OF THE SOURCE. FAILURE TO PROVIDE A RELIABLE NEUTRAL CONNECTION MAY RESULT IN MODULE FAILURE!

SPD Monitoring External Status Indicators — These indicators provide a

summary of the status of the surge SPD module. For normal conditions, the green “OK” LED is illuminated and the red “Service” LED is extinguished. If the surge SPD module requires replacement, the green “OK” LED is turned off and the red “Service” LED illuminated.

Summary Alarm Contact (if applicable) — Summary alarm Form C (1 N.O. and 1 N.C.) relay contacts may be provided for remote indication of the failed surge SPD module.

Contacts are rated 5 amps at 250 VAC maximum with a power factor of 1.0. For units with Summary Alarm Contacts, access to the contacts are typically provided via contact terminals located on the printed circuit board mounted on the inside of the unit’s cover.

Transient Counter (if applicable) – Transient counters are provided for transient voltage surge monitoring. The counter totalizes surges monitored since the last counter reset.

The transient counter monitors line transient voltages. The circuit counts all surges that deviate from the line sine wave. The factory setting is 30% over nominal line voltage. Other settings include 50%, 70%, and 100%.

Swell Counter (if applicable) — The swell counter monitors line to line & line to neutral voltages. It is factory set to record whenever the peak voltage on any normal mode exceeds the nominal voltage of the TVSS for more than 10ms. This counter records temporary line over voltages that may result from utility switching, line regulation problems, etc.

Audible Alarm (if applicable) — If the surge SPD module 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 activating the “Test” switch on the system monitor panel. For information on the AccuVar Series Alarm, see page 16.

Troubleshooting / Servicing / Maintenance

Troubleshooting

If status failure indication occurs or Form C relay has changed states, a qualiﬁ ed electrician shall ﬁ rst determine if the systems voltage and proper phasing exists.

If the SPD remains in an alarm condition once the electrician is satisﬁ ed that the electrical system and its connections are normal, the unit should be repaired. At this point consult the factory, having available the following information:

• Unit identiﬁ cation number – (refers to the model and serial numbers detailed on the data label and is located on the front or upper left [hinge] side of the enclosure.)

• Nature of problem – (including status of all status indicators and alarms).

Servicing

ONLY QUALIFIED PERSONNEL SHOULD PERFORM MAINTENANCE ON THE SYSTEM.

HAZARDOUS VOLTAGES ARE PRESENT INSIDE THE UNIT DURING NORMAL OPERATIONS.

ELECTRICAL SAFETY PRE-CAUTIONS MUST BE FOLLOWED WHEN SERVICING THIS UNIT.

TO PREVENT RISK OF ELECTRICAL SHOCK, TURN OFF AND LOCK OUT ALL POWER SOURCES TO THE UNIT BEFORE SERVICING UNIT.

(For servicing assistance, contact your local Liebert Sales Representative or Liebert at 800-288-6169 or 607-724-2484.)

Corrective Maintenance

The Liebert SPD is designed for years of trouble-free operation. However, even the most reliable equipment may fail under abnormal conditions.

Diagnostic indicators are provided to indicate when the unit needs replacement (see individual SPD operation of this manual for details). To ensure continuity of surge protection, failed units should be replaced at the earliest convenient service opportunity.

When replacing surge modules, other components should be inspected for damage and replaced if necessary. Standard electrical troubleshooting procedures should be used to isolate problems other than failed surge current diverter modules.

When replacing components, for continued proper operation and safety, replace only with identically rated components. Please contact factory for information on replacement parts.

Preventative Maintenance (Inspection and Cleaning)

Periodic system inspections, cleaning, and connection checks are recommended to ensure reliable system performance and continued surge transient protection.

It is difﬁ cult to establish a schedule for preventative maintenance since conditions vary from site to site. Inspections for failed surge modules using available diagnostics should be done routinely (weekly or monthly).
