HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

· Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E.

· This equipment must only be installed and serviced by qualified electrical personnel.

· Turn off all power supplying this equipment before working on or inside equipment.

· Always use a properly rated voltage sensing device to confirm power is off.

· Replace all devices, doors and covers before turning on power to this equipment.

Failure to follow these instructions will result in death or serious injury.

CAUTION

LOSS OF BRANCH CIRCUIT POWER AND SURGE PROTECTION

In the event that the surge protective elements of the SPD have been damaged (i.e. excessive surge energy, power system anomaly, etc.), the surge protective elements can lose their ability to block power system voltage and attempt to draw excessive current from the line. This SPD is equipped with overcurrent and overtemperature protection that will automatically disconnect the surge protective elements from the mains should the surge protective elements be damaged.

The effects of damaged surge protective elements and the subsequent operation of the automatic overcurrent and overtemperature protection must be considered when applying a SPD, particularly when critical loads requiring continuity of power or continuity of surge protection are present on the power system. The following items should be considered when applying a SPD:

· Tripping of the branch circuit breaker feeding the SPD can occur when the surge protective elements are damaged. Do not connect the SPD to a branch circuit feeding a load requiring continuity of power (i.e. central computer or control systems, safety-critical equipment, critical processes or systems, etc.) unless the branch circuit breaker trip characteristic has been coordinated with the overcurrent protection inside the SPD.

· Periodic inspection of the state of the status indicator lights on the SPD should be made as part of the preventive maintenance schedule. The SPD should be promptly serviced when an alarm state exists.

· For unmanned, inaccessible, or critical installations, the dry contacts should be used to signal an alarm state to the central supervisory system.

· In addition to the preceding items, the use of multiple SPDs to achieve redundancy should be considered for critical applications.

Failure to follow these instructions can result in loss of power or loss of surge protection that can cause injury or equipment damage.

WARNING S

CAUTION

LOSS OF SURGE PROTECTION

· During installation into an electrical system, SPDs must not be energized until the electrical system is completely installed, inspected, and tested. All conductors must be connected and functional, including the neutral. The voltage rating of the device and system must always be verified before energizing the surge protective device.

· Any factory or on-site testing of power distribution equipment that exceeds the normal operating voltage, such as high-potential insulation testing, or any other tests where the suppression components will be subjected to voltages higher than their rated turn-on voltage must be performed with the suppressor disconnected from the power source. The neutral connection at the SPD must also be disconnected prior to performing high-potential testing and then reconnected upon completion of the test.

Failure to follow these instructions can result in equipment damage.

Equipment Performance

English versions of all safety labels (danger, warning, caution) are provided.

The device is designed to operate in an ambient temperature range of 0 to +50 °C (+32 to +122 °F) with a relative humidity of 0 to 95% noncondensing. Refer to the product catalog for further details on enclosures. All SPDs operate normally without reduction in performance when subjected to shock and vibrations described in IEC 60721-3-3, Class 3M4.

The device background noise is negligible and does not restrict the location of the installation.

This device is designed to be surface or flush mounted. Refer to the device submittal drawings or the product catalog for typical mounting dimensions and weight. Install the Hubbell Modular Panel SPD in a restricted access area.

The service clearance should meet all applicable code requirements.

To obtain the maximum system performance, locate the device as close as possible to the circuit breaker to minimize the interconnecting wiring length. For every foot in length of wire, approximately 175 volts per foot (6 kV/ 3 kA, 8/20 microsecond) is added to the suppressed voltage. The suppressed voltage rating is located on the device nameplate and is measured 6 inches

from the device terminals, according to UL

1449 Second Edition.

Voltage Rating

Terminals, Wire Size and

Installation Torque

Prior to mounting the SPD, verify that the device has the same voltage rating as the power distribution system in which it is installed by comparing the nameplate voltage or model number on the SPD with the nameplate of the electrical distribution equipment.

The specifier or user of the device should be familiar with the configuration and arrangement of the power distribution system in which any SPD is to be installed. The system configuration of any power distribution system is based strictly on how the secondary windings of the transformer supplying the service entrance main or load are configured. This includes whether or not the transformer windings are referenced to earth via a grounding conductor. The system configuration is not based on how any specific load or equipment is connected to a particular power distribution system.

Terminals are provided for phase (line), neutral, and equipment ground connections. The SPD terminals accept a range of #12 to #2 AWG (34 mm2) copper wire for phase, neutral, and ground connectors. Torque connections to the following values.

Hubbell Modular Panel Surge Protective Device (SPD)

E LECTRIC A L

UNDERSIZED WIRING (USE ONLY CONDUCTORS RATED 30 A OR GREATER.)

· The Hubbell series SPD is designed for connection to a 30 A (or greater) circuit breaker.

· The circuit breaker is the intended disconnect means for the SPD without integral disconnect option and provides overcurrent protection for the connecting conductors.

· The circuit breaker maximum rating should not exceed the ampacity of the connecting conductors.

Failure to follow these instructions will result in death or serious injury.

Turn off all power supplying this equipment through the Panel Circuit Breaker or Primary Disconnect before working on or inside the equipment.

INTEGRAL SWITCH

LOCATION OF SPD

The integral switch is a second mechanical means for qualified maintenance personnel to isolate the entire surge suppressor to service the device’s components. The integral switch opens the phase and neutral connections to the SPD for additional protection.

Turn integral switch handle to the OFF position prior to opening the door of the unit. With the handle in the OFF position, the SPD will be disconnected from the circuit and the circuit will not be protected from surges. Maintenance may now be performed on the Hubbell module and associated parts. Upon completion of repairs, close the door of the unit and turn the handle to the ON position. Close the Panel Circuit Breaker or Primary Disconnect to power SPD.

Install SPDs on the load side of the main overcurrent protection to comply with UL 1449 and the NEC.

Locate the SPD as close as possible to the circuit breaker being protected to minimize the wire length and optimize SPD performance. Avoid long wire runs so that the device will perform as intended. To reduce the impedance that the wire displays to surge currents, the phase, neutral, and ground conductors must be routed within the same conduit and tightly bundled or twisted together to optimize device performance. Avoid sharp bends in the conductors. See Figure 2.

OPERATION AND

LED STATUS INDICATORS

The SPD display panel shows the status of the Hubbell module with diagnostically controlled green/red LEDs. If a unit is operating correctly, all the phase LEDs will be illuminated green. To test the integrity of the diagnostics for each phase, push the button below the phase LEDs on the diagnostic display. The green LED will turn red and the alarm will sound, if the alarm is enabled. Releasing the test button will complete the test; the red LED will turn green and the alarm will shut off.

If an inoperable condition occurs on any phase, the audible alarm sounds and the corresponding phase LED on the diagnostic display panel is illuminated red. This indicates that the device needs service by qualified electrical personnel. The audible alarm can be silenced, until a qualified person is able to evaluate and service the SPD by pressing the alarm enable/disable button. The alarm will silence and the green alarm LED will not be lit. The red phase LED will continue to be illuminated until the inoperative condition had been cleared.

On wye and split phase configuration SPD modules (see Figure 21), if the left green LED is not lit, it indicates a loss of suppression from line-toground for that phase. If the right green LED is not lit, it indicates a loss of suppression from line-to-neutral for that phase. If both green LEDs are not lit and the diagnostic display panel has power, then power has been lost to that phase or module is bad and should be replaced.

CONFIGURATIONS)

AUDIBLE ALARM

SURGE COUNTER

On a delta configured SPD, the module inside the panel does not contain any status LEDs. Instead, there is a blue status LED which is located on the panel backplane directly adjacent to the corresponding module. If the blue LED is not lit, it indicates a loss of suppression from line-to-line for that phase. If the blue LED is not lit and the diagnostic display panel has power, then power has been lost to that phase or the module is bad and should be replaced.

Push the alarm enable/disable button to enable or disable the alarm. If the green alarm LED is lit the alarm is enabled. If the green alarm LED is not lit, the alarm is disabled.

The surge counter displays the number of transient voltage surges since the counter was last reset. The counter is battery powered to retain memory in the event of a power loss to the diagnostic display panel.

To reset the surge counter remove all power and press the small switch located inside the unit on the underside of the diagnostic circuit board (near the communication connectors). This will reset the counter to zero.

(on diagnostic circuit board)

The Hubbell Hardwired series SPD is provided with dry contacts. The connection for the dry contacts is located on the back of the diagnostic display panel (lower right corner). The dry contacts are 3-position, Form “C” type with Normally Open, Normally Closed and Common connections. The unpowered state shall be closed between terminals NC and COM. This is also the alarm condition. The opposite state, closed between terminals NO and COM, indicates that power is on to the unit and that no alarm condition exists (See Table 3). These contacts can be used for remote indication of the SPD’s operating status to a computer interface board or emergency management system. Also, these contacts are designed to work with the SPD remote monitor option described below.

The contacts are designed for a Maximum voltage of 24 VDC and a maximum current of 2 A. Higher energy applications may require additional relay implementation outside the SPD. Damage to the SPD’s relay caused by use with energy levels in excess of those discussed in this instruction bulletin are not covered by warranty. For application questions, contact your Hubbell representative.

Page 19

OPERAT I O N

Hubbell Modular Panel Surge Protective Device (SPD)

Care must be taken in installing the dry contact wiring because the terminals are on a moving door. Avoid the door hinge, any disconnect switches, and the high voltage areas of the enclosure when routing the wiring. To avoid the door hinge, tie wrap any dry contact wiring to the existing cable harness which crosses the hinge. Once the dry contact wiring is secured on a non-moving point of the enclosure, it is the user’s responsibility to maintain separation between dry contact wiring and the power wiring in the enclosure.
