Lectro CPR® Operator’s Manual 2.2 Operation CPR UPS STARTUP AND INVERTER TEST 2.2.1 Verify that all connections to the CPR have been made correctly as described in Section 2.1. 2.2.2 Verify that the desired output voltage has been selected (48V, 60V, 75V, or 87V) via the connection at the left side of the CPR module. Check to see that the AC input cord and Battery power cables are plugged in. 2.2.
Lectro CPR® Operator’s Manual 2.2.6 Check the front panel test points with a true RMS voltmeter. CABLE AC OUT should read within 3-5% (maximum range is tap dependent) of the configured output voltage (48, 60, 75, or 87 V). BATTERY should read between 45 and 56 Vdc, depending on the age, temperature, and state-of charge of the batteries. 2.2.7 Verify that the external LEDs on the CPR outdoor cabinet are functioning. In normal operation, the green external LED will be ON solid, (not flashing).
Lectro CPR® Operator’s Manual 2.3.2 Open the cabinet. Check tightness of all battery, internal ground, and output connections. Observe condition of batteries. If the cabinet shows signs of excessive dust or moisture, check for lost vent screens. Repair as required, and note any unusual conditions for future reference. 2.3.3 Inspect the input surge suppressor (if installed) for obvious damage. If it appears intact, check its operation with a megger or a similar device to ensure that it is functioning.

Lectro CPR® Operator’s Manual 3.1 Safety CAUTION: Short circuit danger: Do not rest tools or equipment on top of batteries. Do not allow batteries to become shorted as an explosion may occur causing severe injury. Do not open or mutilate batteries. Released electrolyte is extremely harmful to skin and eyes. Do not dispose of batteries in fire as an explosion may occur. CAUTION: Government regulations may require that batteries be recycled.
Lectro CPR® Operator’s Manual 3.2.2 3.2.3 3.2.4 3.2.5 3.2.6 Connect the red battery cable which comes from the gray connector on the CPR module to the positive (+) terminal of the left battery. Refer to Figure 3.3-1 for details. Torque all connections to 60 inch-pounds (6.8 Newton-meters). Connect the three (3) battery interconnection jumpers as shown in Figure 3.3-1. Torque all connections to 60 inch-pounds (6.8 Newton-meters). Confirm that the CPR DC circuit breaker is off (down).
Lectro CPR® Operator’s Manual 3.4 Additional Battery String Tools required: 10mm Metric socket Inch-pound torque wrench Multimeter NOTE: This procedure assumes that the additional battery string is being installed in a Lectro brand cabinet. 3.4.1 Confirm that the CPR DC circuit breaker is off (down). 3.4.2 Place the batteries in the bottom of the cabinet with the negative terminals (-) at the rear of the cabinet. Refer to Figure 3.4-1 for details 3.4.
Lectro CPR® Operator’s Manual RED BLACK Upper Shelf Lower Shelf FRONT OF CABINET Figure 3.4-1: Battery Connections – Parallel Strings 3.5 Maintenance 3.5.1 WHILE IN STORAGE Always make sure a battery is fully charged before placing it into storage. Never charge batteries in a gas-tight container. Always store batteries in a cool, dry location. Optimum temperature is 25°C (77°F). Always monitor battery, open-circuit voltage at least once every 12 months.
Lectro CPR® Operator’s Manual A different state of charge condition likely exists if the open circuit voltage for any battery in a string deviates from its neighbor by more than ± 0.25 volts. Never leave a battery in a discharged state for any length of time. 3.5.3 PERIODIC MAINTENANCE Never forget to periodically check batteries for proper terminal attachment torque every 12 months.
Lectro CPR® Operator’s Manual 4: Status Monitor 4.1 Installation The communication module installs in the same basic manner for all three levels of status monitoring. The external connections will be different as defined in Section 4.3. 4.1.1 4.1.2 4.1.3 4.1.4 4.1.5 Turn off the CPR Unit, and remove AC Power. Remove the communication module cover plate (if applicable). Locate and pull out the ribbon cable with the connector, inside of the CPR Communicator module slot.
Lectro CPR® Operator’s Manual 4.2 Operation The operation of the status monitor is automatic and carries out its functions without the direct intervention of the operator. The purpose of the status monitor is to indicate the operating conditions of the CPR power supply. There are three levels of status monitoring: LEVEL ONE is used to indicate locally (at the power supply) only (see Figure 4.3-1). This can be a combination of the external cabinet LED indicators and/or the LED’s on the CPR power supply.
