1 Safety instructions 1.1 Symbols on the UPS and accessories The following are examples of symbols used on the UPS or accessories to alert you to important information: RISK OF ELECTRIC SHOCK - Indicates that a risk of electric shock is present and the associated warning should be observed. DANGER CAUTION: REFER TO OPERATOR’S MANUAL Refer to your operator’s manual for additional information, such as important operating and maintenance instructions.
1.2 Conventions used in this manual This manual uses these type conventions: • Bold type highlights important concepts in discussions, key terms in procedures, and menu options, or represents a command or option that you type or enter at a prompt. • Italic type highlights notes and new terms where they are defined. Icon Description Information notes call attention to important features or instructions. NOTE 1.3 General The battery cabinet contains components that carry high currents and voltages.
WARNING • To reduce the risk of fire or electric shock, install this battery cabinet in a temperature and humidity controlled, indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40 °C (104 °F). Do not operate near water or excessive humidity (95 % maximum). The system is not intended for outdoor use. • Ensure all power sources are disconnected before performing installation or service. Power may come from multiple sources.
• The operating environment should be maintained within the parameters stated in this manual. • Keep surroundings uncluttered, clean, and free from excess moisture. • Observe all DANGER, CAUTION, and WARNING notices affixed to the outside of the equipment. 1.4 Audience The intended audience of this manual is people who plan the installation, install, and use the UPS. This manual provides guidelines for checking the delivery, installing, and operating of the battery cabinet.
1.7 Environment The battery cabinet must be installed and operated according to the recommendations in this manual. Environmental specifications are in chapter 4.3. Ensure proper ventilation. Ensure there are no flammable gases present. Excessive amount of dust in the operating environment of the battery cabinet may cause damage or lead to malfunction. The battery cabinet should always be protected from the outside weather and sunshine.
2 Installation The battery system provides emergency short-term backup power to safeguard operation during brownouts, blackouts, and other power interruptions. By default, 93PM and 93E UPSs are configured to use valve-regulated lead-acid (VRLA) batteries. For the battery specification, see UPS User’s and Installation Guide. Should there be a need to connect other type of batteries or other energy storage means, a certified service technician should be consulted prior to proceeding with installation.
Cable entry to the 93PM UPS is always on the rear or the bottom of the cabinet. In 30-150 kW UPS models the entry is also located on the bottom of the right side panel. Cable entry to the 93E UPS is on the rear or the bottom of the UPS cabinet. For the 80-120 kVA models the bottom cable entry is in the front section of the bottom plate and for the 160-200 kVA models the entry is in the rear section of the bottom plate.
Figure 2 -2: 93P/E battery cabinet (Large Battery Cabinet) A DC-rated circuit breaker within each cabinet provides protection and service isolation. The battery cabinets use convection cooling to regulate internal component temperature. Air inlets are at the bottom and in Large Battery Cabinet also in the front of the cabinet and outlets are on the rear of the cabinet. Clearance must be allowed in front and rear of each cabinet for proper air circulation.
3. Carefully slide the battery cabinet off the pallet. Now the battery cabinet is ready to be placed aside the UPS. Notes of installation location with 93PM UPS: Both sides can be used for battery cabinet placement but for easier service access to UPS, on the 93PM 30-150 kW UPS right side is preferred, and on the 93PM 160-200 kW left side is preferred. The battery cabinet must be located on the right side of 93PM 30-50 kW UPS cabinet if wiring through cabinet side panels.
2.2 Preparing the Large Battery Cabinet installation NOTE The battery cabinet is heavy. If unpacking instructions are not closely followed, the cabinet may tip and cause serious injury. 1. If not already accomplished, use a forklift or other material handling equipment to move the cabinet to the installation area, or as close as possible, before unloading from the pallet. Insert the forklift jacks between the skids on the bottom of the unit. 2.
5. Select the cable routing out of different options and route the cables to the dedicated connectors inside UPS cabinet. Terminals are located under the circuit breaker and are marked with +, - and a protecting earth designators. 6. Apply cable glands and/or plastic pass-through collars accordingly. WARNING Make sure all power sources are disconnected before next steps. 7. Connect the power cables and signal wires to the UPS. No signal wires are connected to 93E UPS. 8.
Cable connection to battery poles is to be done as follows: Figure 2 -5: Cable connection on b attery poles 9. If multiple cabinets are to be used, repeat the steps for the rest of the cabinets and in 93PM system be sure to daisy chain the signal wire harnesses in the next cabinet. 93E system does not use signal wiring. Signal wires are daisy chained by cutting the multiple connector and extra length of the cables and connecting them to TB2 terminals 5-8. Look at the Figure 2-6.
2.3 Installation with other than 93PM or 93E UPS Other UPSs may not be fully compatible with 93P/E External Battery Cabinet. Check UPS manual for the requirements for the external battery supply.
3 Maintenance The components inside the cabinet are secured to a sturdy metal frame. All repairable parts and assemblies are located for easy removal, with very little disassembly. This design allows authorized service personnel to perform routine maintenance and servicing quickly. You must schedule periodic performance checks of your UPS system to keep it running properly. Regular routine checks of operation and system parameters enable your system to function efficiently for many trouble-free years. 3.
When replacing batteries, use the same number of sealed, lead-acid batteries. Proper disposal of batteries is required. Refer to your local codes for disposal requirements. 3.2 Performing preventive maintenance The battery cabinets require very little preventive maintenance.
These symbols indicate on a product Figure 3 -1: WEEE symbol Use proper local collecting centers meeting local legislation when handling waste of electrical and electronic equipment. DANGER HAZARDOUS MATERIALS. Batteries may contain HIGH VOLTAGES, and CAUSTIC, TOXIC and FLAMMABLE substances. Batteries can injure or kill people and damage equipment if used improperly. DO NOT DISCARD unwanted batteries or battery material in the public waste disposal system.
