NEW BATTERY INSTALLATION

1. SCOPE

1.1. This specification covers the procedures to be followed when installing new stationary lead-acid storage batteries.

2. RECEIVING

2.1. Immediately upon delivery of the battery, examine for possible damage caused in transit.

Damaged cartons or packing material stained from leaking acid would be an indication of rough handling and should be noted on delivery of receipt.

2.2. Damaged or stained cartons should be opened immediately and contents inspected. If cell damage is found request an inspection by the carrier, file a damage claim, and notify the department responsible for purchasing the battery.

3. UNPACKING

3.1. Support the cells from the bottom when handling and unpacking. Never lift cells by their posts.

At all times exercise care when handling cells to prevent scratching of plastic jars and covers which could result in stressing and rupturing of the jar.

3.2. At the first opportunity, check the electrolyte level in each cell. Electrolyte levels may range from the high level line to slightly below the low level line. If the plates are covered but the level is below the low level mark, make no water additions until cells have been on float charge for one week. If the electrolyte level is below the top of the plates with less than 1/2" of the plate exposed, contact the manufacturer immediately for the purpose of adding sulphuric acid. If the level is 1/2" or more below the top of the plates, file a claim for concealed damage against the carrier and order a new cell.

3.3. Make certain that all accessories (intercell connectors, bolts, nuts, washers, terminal plates, cables, and flame arresters) have been received. If parts are missing contact the manufacturer.

4. STORAGE

4.1. The battery should be installed and given its initial charge as soon after receipt as possible.

4.2. The storage interval from date of shipment to date of initial charge should not exceed six (6) months for lead-calcium type batteries, with boost charges repeated at each additional six (6) month storage interval.

4.3. Connect the cells with temporary jumpers so that the initial boost or charge can be given to individual cells, group of cells, or preferably to the entire battery. Lead-calcium cells should be charged at 2.33 volts per cell (1.5 volts per cell if Nickel Cadmium) for approximately 144 hours (six days). This time period is for cell temperatures of 70°F to 90°F.

5. RACKS

5.1. Assemble racks in accordance with manufacturer's instructions. To provide sufficient stability, two and three tier racks must be securely anchored to either the floor or wall.

5.2. Metal racks shall be connected solidly to the station grounding system.

6. PLACEMENT OF CELLS

6.1. Determine beforehand the proper location of the positive and negative terminal of the battery so correct positioning of the initial cell on each rack row can be established.

6.2. Mark the center of the rack, determine the number of cells to be placed in each row, and proceed to place the first cell at the center working out to the two ends.

6.3. The standard spacing between cells is 1/2" at the top of the jars.

6.4. Cells shall be installed with the plates perpendicular to rack length.

6.5. Check so that the positive (+) terminal of each cell adjoins the negative (-) terminal of the next cell.

7. CONNECTING CELLS

7.1. The cell posts have been coated with corrosive resistant grease at the factory. Remove this grease from the contact surface with a dry cloth, neutralize the area with a bicarbonate and water solution and dry thoroughly. Clean the post contact surface with a plastic or fiber bristle brush or "scotch brite" scouring pad to provide a bright, shiny finish. Immediately coat with NO-OX-ID grease. Use care so as not to remove the lead plating and expose any bare copper.

7.2. The contact surface of the lead plated intercell connectors should be gently brushed the same as the posts until a bright, shiny surface is obtained and then apply a thin coat of NO-OX-ID grease to the contact surface of the intercell connector. If required, heat the NO-OX-ID grease to a cream-like consistency on an electric hot plate (160°F to 185°F) using extreme care not to overheat.

7.3. Install intercell connectors, adjust them to a level position and finger tighten hardware. Tighten the connections using two insulated wrenches in which one of them is a torque wrench (inch -pounds). Initially, torque the connections within each row to five inch-pounds below the manufacturer's recommended value.

7.4. After all the calls within the row have been connected, re-torque the connections to the manufacturer's recommended value.

7.5. Complete connecting of cells by installing necessary inter-row, inter-tier or inter-rack cable connectors. Do not connect battery to charger or bus at this time.

7.6. Before connecting the main terminals and charger leads to the battery, re-check to be certain that the cells are connected positive (+) to negative (-) throughout the battery string and then measure the total voltage of the cells in the battery. The measurement should be equal to the voltage of one of the cells (2.05 volts) times the number of cells. If the reading is less than this value, one or more of the cells are installed backwards.

7.7. Do not cutover battery and charger to station load via disconnect switch (if applicable) until

C-1504 C-1504 PAGE 3 of 4 PAGE 3 of 4

COMMONWEALTH EDISON COMPANY

SYSTEM STANDARD

sections 8.0 thru 10.0 are completed.

8. COMPLETING INSTALLATION

8.1. Remove cell vent caps and install the flame arresters.

8.2. Install plastic cell numbers and battery terminal polarity labels to cell jars. The positive terminal cell is usually designated as cell #1 in the series string. NOTE: Do not cover up cell electrolyte level line area with labels.

8.3. Mount hydrometer holder on wall close to battery.

8.4. "No Smoking" signs should be posted in the battery area.

8.5. Do not cutover battery and charger to station load via disconnect switch (if applicable) until sections 9.0 thru 10.0 are completed.

9. INITIAL CHARGE

9.1. As soon as possible after installation, the battery should be given an initial charge of 2.33 volts per cell for a lead-calcium battery (135.1 volts for a 58 cell battery) or 1.5 volts per cell for a Nickel Cadmium battery (54.0 volts for a 36 cell battery) for approximately 144 hours (six days).

If 144 hours is not feasible,72 hours is acceptable.

NOTE: Manufacturer’s recommended initial charge requirements may be followed in lieu of 9.1, but do not exceed 2.5 VPC (lead-calcium) at a maximum of 36 hours (cell temperatures between 60°F to 90°F) or when manufacturer recommended charge completion criteria is met.

9.2. On completion of this charge, a voltage and specific gravity reading of each cell should be taken and recorded.

9.3. Do not cutover battery and charger to station load via disconnect switch (if applicable) until section 10.0 is completed.

10. FINAL TEST AND INSPECTION

After the initial charge of the battery, at a minimum perform the following:

10.1. Measure and record overall battery float and equalize voltage at the terminals. Acceptable battery terminal voltages are as follows:
