Receiving and Inspection Notes
Before accepting the shipment from the freight carrier, inspect the exterior surfaces of all shipping containers or packaging used, and the equipment, for damage that may have occurred during transit. If the shipping containers or equipment shows evidence of damage, note the damage on the receiving document (bill of lading) prior to signing for receipt of equipment.
ALL CLAIMS FOR SHIPPING DAMAGE MUST BE FILED DIRECTLY WITH THE CARRIER. Replacements for damaged components should be ordered through MGE UPS SYSTEMS.
Check by thorough inspection if any electrical connections have become loose because of vibration during shipment. Remove top and side panels (Not applicable on 225kVA and larger).
Check the nameplate to be sure that the voltage and frequency match the available power supply. Under no circumstance should the unit be connected to a power source which does not conform to the nameplate rating.
1.3.1
Location and Storage
The unit has been completely inspected and extensively tested under various load conditions prior to shipment.
Care to install it at a proper location will assure long trouble free operation. The unit is forced air cooled with the air intake at the bottom, front or sides and exhausts out at the top or rear. Therefore, it should be installed in a clean, dry place with enough clearance to allow a free flow of air.
Allow at least 4 inches of space between the unit and the wall or other equipment for portable units.
Allow enough space for maintenance as indicated on the cabinet outlines. See Section 2.0, Figures 2-1 thru 2-4. If the equipment is to be stored prior to installation, it should be stored in a cool, dry, well-ventilated location that is protected from rain, splashing water, chemical agents, etc. The equipment should be covered with a tarpaulin or plastic wrapper to protect it against dust, dirt, paint, or other foreign materials.
General Description
The Power-Sure™ 700 is a continuous duty power conditioner designed to supply reliable, clean regulated power to critical loads. An efficient design with state of the art micro-processor controlled solid state devices provide immunity to all line disturbances. The cabinet is a heavy gauge industrial steel throughout. Metal is anti-corrosive phosphate treated prior to paint. Paint is a baked finish.
The basic design consists of a three phase triple shielded isolation transformer with seven separate voltage taps per phase. Output regulation is achieved by monitoring the input and automatically switching taps anytime the input line sags or surges. The use of a triple shielded isolation transformer provides superior common mode and transverse mode noise attenuation. Automatic switching occurs during current zero allowing noise free switches for both leading and lagging power factor loads that are connected to the Power-Sure™ 700.
The Power-Sure™ 700 Power Conditioner is operated by simply turning on the main AC input circuit breaker. As an option, units may have a bypass switch. This is a no load switch and MUST only be operated when the unit is OFF.
The bypass switch should be in the “NORMAL” position unless a problem occurs with the system. If a problem occurs, turn OFF the main AC circuit breaker and turn the bypass switch to the “BYPASS” position. Re-energize the system by turning on the AC circuit breaker and contact the Customer Care Center for repairs.
Any ‘ALERT” condition requires the main AC input breaker to be turned off in order to reset the “ALERT” light.

Input Breaker
Main input molded case circuit breaker, rated at 125% of full load input current.
Monitoring the Power-Sure™ 700
Monitoring of the Power-Sure™ 700 is simple, clean, and effective. Three green light indicators are utilized to display “POWER ON” (output line to neutral for each phase) and one red light indicator to display “ALERT”. The
“POWER ON” display is connected directly to the output that indicates the Power-Sure™ 700 is operating properly with just a quick glance. The “ALERT” display represents an overtemp problem or output voltage loss (optional) when illuminated, and will shut down the output, but cooling fans remain on. Overtemp thermal sensors are strategically located at critical points on the regulator assemblies and transformer. The main AC input circuit breaker must be turned off in order to reset the “ALERT” light.
Protection for the Power-Sure™ 700
Protection is accomplished very effectively to minimize failures and the cost of repairs by the four major methods listed below:
1.
The input is protected with a integrally mounted AC circuit breaker for abnormal current overloads and provides a convenient means of disconnecting utility power.
As an option, the input breaker may be equipped with a shunt trip device that is interfaced with a REMOTE
EMERGENCY POWER OFF PUSH BUTTON. By pressing this button, the input breaker will trip and disable the Power-Sure™ 700 completely. The input breaker must be physically reset before unit will turn on again.
2.
The electronic regulating devices are protected with fast acting semi-conductor fuses. These fuses are designed to clear before damage occurs to the more expensive SCR regulating devices. The main transformer is protected by fuse links connecting the SCR regulators together, and are designed to clear in the event that two or more SCRs should fail. This will prevent a transformer tap short and the possibility of transformer failure.
3. When provided with the optional Under/Over Voltage Shutdown Card (UOV2020), the output of the
Power-Sure™ 700 is constantly monitored for extreme over and under voltage conditions. This card monitors each output phase and will electronically disable the Power-Sure™ 700 when any phase exceeds +10% or
-10% of nominal output voltage.
4.
Overtemp sensing devices are mounted at critical points on the SCR regulating assembly and the main transformer. When an overtemp condition exists the “ALERT” light will illuminate and hold until the overtemp is corrected. There are no automatic shutoff circuits for the “ALERT” condition. The main AC input breaker must be turned off in order to reset the “ALERT” light.

General Operation Notes
The Power-Sure™ 700 Power Conditioners provides the triple function of isolation, noise attenuation and voltage regulation. The first two functions are provided by the power transformer, where as the third function of voltage regulation is achieved through solid state thyristors (SCRs) connected to taps on the power transformer. A micro-processor monitors and controls the overall function of regulating the system.
The power transformer is manufactured with a unique method of shielding which produces very low capacitive coupling between the primary and secondary. This low coupling provides excellent attenuation of the common-mode noise. In addition, special care is taken in the design of the transformer to attenuate transverse-mode noise above
1000 Hz. The power transformer has taps to which solid state switches (SCRs) are connected.
The voltage regulator incorporated in the Power-Sure™ 700 Power Conditioners is microprocessor controlled to achieve optimum correction time of input voltage sags and surges. The response time is typically one (1/2) cycle for
100% correction, therefore, a very smooth switch takes place undetected by computer equipment.
86-108814-00 B01 Installation and Operation 2 — 5
Power-Sure™ 700 — Three Phase Power Conditioners
2.5
As the input voltage (building power) varies, the voltage available at each tap of the transformer will also change.
The amount of variation is dependent upon the input sag or surge, turns ratio and transformer losses.
By selecting a particular tap voltage, the output can be kept within a tight range. The way in which this is accomplished is that an electronic control card using a micro-processor continually monitors the input voltage. When a voltage fluctuation occurs, which exceeds the limit of rated regulation (typically ± 3%), the output is switched to another tap, that is within the required range. This switch will be made at the next current zero crossing to allow for both leading and lagging power loads to be connected to the conditioner.
Power-Sure™ 700 Cable Connections
2.5.1
Input Wire Size, Grounding, and Output Wiring
◗ Conduit should be used for both input and output wiring.
◗ Minimum ground wire size is based on 1990 Nation Electric Code Table 250-95.
◗ Input wire size is based on 1990 NEC Table 310-16 specifying not more than 3 conductors in a raceway based on ambient of 30 degrees Celsius, and wire rated at 75 degrees Celsius.
◗
Output neutral to ground is already bonded during manufacturing of Power Conditioner.
◗ Output requires 4 (5 including ground wire) conductors in a raceway assuming neutral as a current carrying conductor. This requires conductors to be derated by using a multiplier of .8, reference 1990 NEC
Article 310 Section 8A.
Example:
1.
Assume #10 wire max current = 25 Amps.
2.
Multiply 25 x .8 = 20.
3.
20 Amps is max current for #10 wire in a raceway with 4 conductors.
NOTE: Installation is subject to local codes – verify with a local electrical inspector.

WARNING: HIGH VOLTAGE DANGER OF ELECTRICAL SHOCK, TURN OFF ALL POWER
SUPPLING THIS EQUIPMENT PRIOR TO MAINTENANCE. ONLY QUALIFIED
ELECTRICIANS SHOULD PERFORM MAINTENANCE OR TROUBLE SHOOTING.
3.1
Preventive Maintenance
To ensure longer component life and trouble free operation, minor preventive maintenance procedures should be performed at regular intervals, recommended once every year. More frequent inspection intervals would be needed for more severe operation conditions and and larger number of hours of continuous operation.
At each service inspection, remove any dust, dirt or foreign particles. Thoroughly inspect and tighten any loose electrical connections. A slight tug should be used to test if there are any loose electrical connections. Make sure all cooling fans are running.
A.
At each service inspection, remove top and side panels and carefully remove any accumulated dust, dirt, or foreign particles. Special care should be exercised in cleaning the thyristors, heat sinks, and the control assembly.
B.
Inverse Parallel Silicon Rectifiers (SCRs) or Thyristors.
The silicon controlled rectifiers (SCRs) usually fail in the shorted mode. When this happens, normally the fusible link within the SCR will be blown open to clear the short and prevent damage to the transformers. The individual
SCR can be checked with an ohmmeter. Refer to Section 3.4 for resistance checking procedures.
C. A simple performance checklist has been developed for use in maintenance, on pages 3-2 and 3-3. Check off items 1-8.
D. After items 1-8 have been checked on the performance checklist, the next step is to check the operation of the system.
E.
Replace top and side panels. Turn unit on with no load. Check item 9 on the performance checklist.
F.
Turn on loads and check items 10-13 of the performance checklist.
NOTE: Preventive Maintenance plans are available. Please contact the Customer Care

3.
Remove the top and side covers to the conditioner.
3.3.2
Step 2. Electrical Connections, Fuses
Refer to Sections 3.7 and 3.8 for component locations.
1.
Inspect the unit for proper tightness of all electrical connections, burnt, frayed, broken or loose connections, and components in these areas.
2.
Input and output connections, SCR assembly, SCR snubber, output filter assembly, MOVs (metal oxide varistors), circuit boards, bypass switch, and transformer connections need to be checked.
3.
Correct and tighten any loose connections. Replace any physically burned or broken components.
4.
Check all fuses in system (see NOTE). Also check time delay fuses, semi-conductor fuses, fan fuses, circuit board fuses, and SCR fusible link wire.
NOTE: Remove fuses from circuit when checking to avoid false readings.
3.4
Checking the Power Modules (SCR)
Refer to Section 3.8 Figures for specific 10-30kVA SCR, 45-50kVA SCR, 75-150kVA SCR, and 225-300kVA for SCR assemblies.
1.
Unplug the connections to the control cards Part #49120/407415 labeled TB1, TB2, and TB3.
2.
Disconnect any cooling fans in the unit so your SCR resistance checks are not interfered with by fan motor coils.

86-108814-00 B01 Maintenance 3 —5
Power-Sure™ 700 — Three Phase Power Conditioners
NOTE: When checking the power module assembly, if more than one defective power module is present it will appear as if all the power modules are defective.
The individual power module must be isolated from the power transformer:
◗ K1-1 to K2-1 thru K1-7 to K2-7 = High resistance, 1 Meg Ohm.
◗ K1-1 to G1-1 thru K1-7 to G1-7 = 10 to 90 Ohms.
◗
K1-1 to G2-1 thru K1-7 to G2-7 = 1 Meg Ohm.
◗ K2-1 to G2-2 thru K2-7 to G2-7 = 10 to 90 Ohms.
◗ K2-1 to G1-1 thru K2-7 to G1-7 = 1 Meg Ohm.
◗ G1-1 to G2-1 thru G1-7 to G2-7 = 1 Meg Ohm.
4.
Replace any defective power modules. This may require removing the shunt and loosening the K1 bus from all the power modules to get the defective power module out. Use only equivalent hardware and heat sink grease when replacing power modules.
5.
If a resistance measure is questionable, a more thorough test will assure an SCR is good or bad.
Test procedure:
◗
Completely isolate SCR under test by removing all connections to the device.
◗ Hook up the following test circuit to each individual SCR.
◗ Plug in SCR tester. With Switch #1, open light bulb should be off. If not, replace SCR.
◗ Close Switch #1. Light bulb should illuminate to about 3/4 brilliance. If not, replace SCR.
Figure 3-2: Test Wire Diagram.

6.
Reassemble the power module assembly, making sure all connections are tight.
DO NOT CONNECT THE SEMI-CONDUCTOR FUSE, WIRES OR FAN WIRES AT THIS POINT.
Check SCR Snubber Card
Three components make up the SCR snubber: Resistors, MOVs and Capacitors.
◗ Check for open resistors.
◗ Check MOVs for shorts, they should read high resistance when ohm meter is placed across them.
◗ Resistance check each capacitor. The DC resistance across the snubber capacitor should look capacitive, that is high resistance after the meter charges the capacitor.
◗ If it measures open or shorted, replace the snubber card.

DO NOT CONNECT TB1, TB2, and TB3 CONNECTORS FROM THE CONTROL CARDS #49120/407415 YET!
3.5.1
Check Control Card and Filter Card
1.
Verify input to the conditioner matches the units specification. Also verify correct control board #49120 / 407415 jumper setup. See Figure 3-11, Page 3-16.
2.
Disable the over/under voltage shutdown card #35867 (optional card) by removing connectors K1 and K2 on the card.
3.
Turn on AC input breaker to unit.
IMPORTANT: Extreme caution must be taken when measuring voltages on Molex connectors.
Do not press meter leads into connectors or bend connectors back.
4.
Measure the following voltages on wires feeding the TB1 Molex connector to the control card on all 3 phases.
Pins 1 & 3 = 4-6 VAC.
Pins 7 & 8 = 120 VAC
NOTE: When the connector is plugged in, this voltage is around 3 VAC.
If this voltage is incorrect or not present, then check the fuses associated with the filter card or replace filter card and re-check voltages.
5.
Turn main AC circuit breaker off. Plug in connectors TB1 and TB3 ONLY on the control card #49120/407415 on all 3 phases.
6.
Turn main AC on. With DC voltmeter on the millivolt scale check between TP1 and TP GND of the control card and adjust pot P2 so meter reads “0” millivolts or close as possible.
NOTE: This step does not apply to Control Board #407415.
7.
Use the following formula to calculate the next adjustments. You must calculate each input phase for each control card or a total of 3 calculations.
◗ For phase 1, control card measures AC input at Line 1 to Line 2.
◗ For phase 2, control card measures AC input at Line 2 to Line 3.
◗ For phase 3, control card measures AC input at Line 1 to Line 3.

NOTE: If adjustments in Steps 6 and 7 are not possible, replace control card
#49120/407415 and repeat Steps 6 and 8.
Be sure to turn power off when replacing circuit boards.
Be sure AC input is stable when making this adjustment. If the input changes, you must re-calculate.
Output voltage correction is a “stepped correction”. Adjusting P1 will not cause a smooth change in output voltage as it is adjusted.
9.
Turn the unit off. Plug in TB2 Molex connectors to all the control cards #49120/407415.
10.
Replace connectors K1 and K2 on over/under detect #35867.
NOTE: P1 pot turned clockwise = decrease in output voltage and counter-clockwise = increase in output voltage. By changing this adjustment on phase1 you may see the output voltage change from line to neutral on two phases. It is best to use procedures in Steps 1 – 9 of Section 3.6.
3.6
Final Testing and Adjustments
1.
Connect AC voltmeter to output of system with proper meter scale selected.
NOTE: On 3 phase systems, connect your AC voltmeter across the output phase to neutral.
2.
Disconnect customers loads.
3.
Energize system.
4.
Verify the output is within specifications. If not, adjust P1 on control board, for the appropriate phase. See
Section 3.9.2, Control Card Adjustment Procedure, page 3-16.
NOTE: On 3 phase systems, be sure and check all 3 phases.
If the main AC breaker trips or there is no output voltage, disable the over/under detect circuit #35867 by disconnecting K1 and K2 connectors and then calibrate the control boards if the output voltage is out of spec.

Power-Sure™ 700 Control Card #49120/407415
WARNING: ALL SERVICE TO THIS PIECE OF EQUIPMENT MUST BY PERFORMED BY
QUALIFIED PERSONNEL.
86-108814-00 B01 Maintenance 3 —15
Power-Sure™ 700 — Three Phase Power Conditioners
CAUTION: THE CONTROL BOARD (#49120/407415) IS ELECTRICALLY REFERENCED TO
HIGH VOLTAGE, NOT EARTH OR CHASSIS GROUND. EXTREME CARE MUST BE
USED WHEN TAKING MEASUREMENTS ON THE CONTROL BOARD. ANY AC
POWERED INSTRUMENTS MUST BE GROUND ISOLATED PRIOR TO TAKING
MEASUREMENTS. A GROUND ISOLATED INSTRUMENT CASE WILL BE AT THE
HIGH VOLTAGE LINE POTENTIAL.
3.9.2 Control Card Adjustment Procedure
1.
Prior to attempting any adjustment, measure the incoming voltage to the unit. Assure the voltage level is within the specified input range of the unit.
2.
Turn off power to unit.
3.
Remove all loads from the output of unit under adjustment.
4.
Remove both TB2 connectors on all control boards #49120/407415. Turn power on.
5.
With DC voltmeter on the millivolt scale check between TP1 and TP GND and adjust P2 so meter reads “0” millivolts or as close as possible.

6.
Use Formula X below to calculate the next adjustments. You must calculate each input phase for each control card or a total of 3 calculations:
◗ For phase 1 control card, measure AC input at Line 1 to Line 2.
◗ For phase 2 control card, measure AC input at Line 2 to Line 3.
◗ For phase 3 control card, measure AC input at Line 1 to Line 3.
3 —16 Maintenance 86-108814-00 B01
Installation and User Manual
Example:
FORMULA X
AC Input x 2.47
= Volts DC at TP2
480 (Nominal)
475 Volts AC Input x 2.47 = 2.44 Volts DC at TP2
480 (Nominal)
NOTE: Be sure AC input is stable when making this adjustment. If the input changes, you must re-calculate.
7.
After calculations are complete, place DC voltmeter on 20 volt scale and check between TP2 and TP GND on control card. Adjust pot P1 so meter reads DC level calculated in Step 6 for all 3 phases.
NOTE: Output voltage correction is a “stepped correction”, adjusting P1 will not cause a smooth change in output voltage as it is adjusted.
8.
Turn unit off and reconnect TB2 connectors on all control boards.
9.
Turn unit on and verify output is correct by monitoring the output from each line to neutral.
If output is not correct, make sure input power is stable and repeat adjustment procedure.
NOTE: P1 Pot turned clockwise = decrease in output voltage and counter-clockwise = increase in output voltage. By changing this adjustment on 1 phase you may see the output voltage change from line to neutral on 2 phases. It is best to use procedures in Steps 1-9 when adjusting.
3.9.3
Over/Under Voltage Detection Board #35867
NOTE: Adjustments are referenced from the units output.
3.9.3.1 Undervoltage Adjustment
1.
The under voltage adjustment can be adjusted from -1% (118.5 VAC) to -20% (95 VAC) The standard setpoint is -10% (108 VAC).
2.
P2 will adjust the undervoltage set point. One turn on P2 will change the voltage level approximately
1 volt.
Clockwise = Increase in sensitivity.
Counter-clockwise = Decrease in sensitivity.
3.9.3.2 Overvoltage Adjustment
1.
The over voltage adjustment can be adjusted from +1% (121 VAC) to +20% (145 VAC).
The standard set point is +10% (132 VAC).
86-108814-00 B01 Maintenance 3 —17
Power-Sure™ 700 — Three Phase Power Conditioners
2.
P1 will adjust the overvoltage set point. One turn on P1 will change the voltage level approximately 1 volt.
Clockwise = Decrease Sensitivity.
Counter-clockwise = Increase Sensitivity.
3.9.3.3 Delay Adjustment
1.
The delay adjustment can be adjusted for a minimum of 5 cycles to a maximum of 15 seconds.
The standard set point is 6 seconds.
2.
P3 adjusts the delay.
◗ All the way counter-clockwise = 5 cycles.
◗ All the way clockwise = 15 seconds.
After two turns clockwise from the full counter-clockwise position, each turn equals approximately
1/2 second.
3.10
Manual Bypass Switch Option
The manual bypass switch is a break before make switch located on the Power-Sure™ 700. The manual bypass switch is used to bypass all power electronics in case of failure.
NOTE: This switch may be added in the field.
3.10.1 Normal Mode
With the switch in the normal position, the Power-Sure™ 700 will provide clean and regulated power to the critical loads. The Power-Sure™ 700 should have the switch in the normal position unless a failure has occurred.
3.10.2 Bypass Mode
With the switch in the bypass position, the Power-Sure™ 700 will provide clean power to the critical loads. In the bypass position, the unit will not regulate the incoming voltage. The Power-Sure™ 700 should be placed in the bypass position when a failure of the system has occurred. This provides the user with some protection until a service technician arrives.
CAUTION: PRIOR TO SWITCHING FROM ONE POSITION TO ANOTHER, TURN OFF THE
AC INPUT BREAKER. SOME SYSTEMS ARE EQUIPPED WITH PUSH-TO-TURN
SWITCHES. WITH THESE SWITCHES THE SWITCH WILL SHUNT TRIP THE
INPUT BREAKER WHEN PRESSED IN.
3.10.3 Remote Emergency Power OFF (REPO) (Optional)
The REPO is operated by a remote push button that when depressed will shunt trip the Power-Sure™ 700 input breaker and disable the unit. This option may be added to units in the field. Contact the Customer Care Center if you wish to add these options.

MGE Warranty & Proprietary Rights Statement for Three Phase Products
(Applicable within the United States, Canada and Mexico)
MGE Standard Three Phase Warranty
MGE UPS SYSTEMS, INC. (“MGE”) warrants three phase products it manufactures to be free from defects in materials and workmanship for a period of three hundred sixty five (365) days counting from the date of purchase by or for the first end user (“Purchaser”), or, if applicable, the date of MGE’s completion of initial startup of the subject product, provided however said warranty shall not exceed eighteen (18) months from the date of delivery of the subject product to Purchaser (the
“Warranty Period”). MGE’s liability hereunder is limited to replacing or repairing at MGE’s factory or on the job site, at
MGE’s option, any part or parts that are defective and reported to MGE during the Warranty Period. MGE shall have the sole right to determine if the parts are to be repaired at the job site or whether they are to be returned to the factory for repair or replacement. All items returned to MGE for repair or replacement must be sent freight prepaid to its factory.
Purchaser must obtain MGE’s Return Goods Authorization (“RGA”) prior to returning items. The conditions stated herein must be met for MGE’s warranty to be valid. MGE will not be liable for any damage caused by or resulting from unauthorized repair work, unauthorized replacement parts, from any unintended application of the Three Phase Product, for damage due to accident, abuse, or act of God (such as earthquake, flood, inclement weather, rain or fire), or relating to Purchaser’s failure to provide proper environmental conditions for the product.
In no event shall MGE be liable for loss, damage, or expense directly or indirectly arising from the use of or any defects in the subject product, or from any other cause, except as expressly stated in this warranty. EXCEPT AS EXPRESSLY STAT-
ED IN THIS WARRANTY, MGE MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY AS TO
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR USE OR NON-INFRINGEMENT. MGE is not liable for and Purchaser waives any right of action it has or may have against MGE for any consequential or special damages arising out of any breach of warranty, and for any damages Purchaser may claim for damage to any property or injury or death to any person arising out of its purchase or the use, operation or maintenance of the subject product. The warranty stated herein includes parts and labor; however, MGE will not be liable for any labor subcontracted or performed by Purchaser for preparation of the warranted item for return to MGE’s factory or for preparation work for field repair or replacement, and
MGE will not be responsible to pay any invoice therefore.
This warranty shall be exclusive of any and all other warranties express or implied and may be modified only by a writing signed by an authorized officer of MGE. This warranty shall extend to the Purchaser but to no one else. Accessories supplied by MGE, but manufactured by others, carry any warranty the manufacturers have made to MGE, and which can be passed on to the Purchaser.
MGE makes no warranty with respect to whether the products sold hereunder infringe any patent, U.S. or foreign, and
Purchaser represents that any specially ordered products do not infringe any patent. Purchaser agrees to indemnify and hold MGE harmless from any liability by virtue of any patent claims where Purchaser has ordered a product design based on the Purchaser’s specifications, or conforming to Purchaser’s specific design.
Purchaser has not relied and shall not rely on any oral representation regarding any products sold hereunder and any oral representation shall not bind MGE and shall not be part of this or any other any warranty. There are no warranties which extend beyond the description on the face hereof. In no event shall MGE UPS SYSTEMS, INC. be responsible for consequential damages or for any other damages except as expressly stated herein.
