• Be trained in rendering first aid. For further information on workplace safety visit www.osha.gov. 2.4 Factory Authorized Personnel Factory authorized personnel have been factory trained and certified to install, service, and repair the UPS. Contact the Toshiba Customer Support Center for assistance in locating the factory authorized personnel nearest you.
4 Safety Precautions The Toshiba products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances, etc.). These Toshiba products are neither intended nor warranted for use in equipment that, if a malfunction or failure occurs, may result in loss of human life or bodily injury (collectively referred to as “Unintended Usage”).
4.2 General Maintenance warning DO NOT remove the rear/side panels, or any sheet metla not designed to be removed. Removing rear/side panels may result in electric shock, burns, personal injuries or UPS failure. Keep the area arround the UPS clean. Use a vacuum cleaner to clean the UPS. Only factory authorized personnel sould perform internal general maintenance on the UPS.
caution DO NOT transport, move, store, or place the UPS on its side. Forces due to heavy components inside may damage the UPS. Avoid vibration or shock exceeding 0.5G. Failing to observe this precaution may cause damage to the UPS. DO NOT allow the UPS to suffer shock or impact when unpacking. Tools used to remove packaging materials may cause damage to the UPS. DO NOT push or pull on the sides of the packaging.or the UPS to move it.
4.4 Inspection/Storage Inspection Upon receipt of the UPS, an inspection for shipping damage should be performed. Use caution when removing the unit from the pallet. Refer to labels or documentation attached to packing material. Unpacking Check the unit for loose, broken, bent or otherwise damaged parts. If damage has occurred during shipping, keep all original crating and packing materials for return to the shipping agent.
5 Installation Precautions caution Install the UPS in a controlled environment. Improper storage and installation environment may deteriorate insulation, shorten component life and cause malfunctions. See Table 5.1 - UPS Installation Environment Standards DO NOT tilt the UPS more than 10° from upright position. Tilting the UPS more than 10° may cause crushing, trapping or other personal injuries and cause physical damage to internal components. warning Keep the SPECIFIED CLEARANCE around the UPS.
DO NOT block air vents. Blocking the vents will increase the internal temperatures and may result in UPS failure or fire. DO NOT install the UPS where water may fall on it. Water may cause electrical shock, personal injury or UPS failure. DO NOT use floor wax that contains silicon in the UPS storage area and/or nearby rooms. Floor wax that contains silicon may cause static electricity. warning The UPS should be installed per local and/or national electric codes by qualified personnel.
TABLE 5.1 - UPS INSTALLATION ENVIRONMENT STANDARDS Item Environment standard Installation Location Indoors Minimum operating temperature: 32 °F (0 °C). Maximum operating temperature: 86 °F (30 °C) at 1.0 PF (UPS with/without battery system). Ambient Temperature Maximum operating temperature: 90 °F (32 °C) at 0.8 PF (UPS with battery system). Maximum operating temperature: 104 °F (40 °C) at 0.8 PF (UPS only). Average 24-hour operating temperature: 86 °F (30 °C) at 1.0 PF and 41 – 95 °F (5 – 35 °C) at 0.
7) The UPS generates and can radiate radio-frequency energy during operation. Although RFI noise filters are installed inside of the unit, there is no guarantee that the UPS will not influence some sensitive devices that are operating near by. If such interference is experienced, the UPS should be installed further away from the affected equipment and/or powered from a different source than that of the installed equipment.
5.1 Wiring/Connection WARNING Perform wiring and connections with correct polarity. Be careful when connecting the UPS to the battery system. A wrong connection may cause damage to the UPS, battery, or charger. Connect ONLY one (1) ground wire to the earth ground terminal. A missing ground wire may cause an electrical shock hazard. Connecting to more than one ground may cause a ground loop. See Chapter 8 - UPS Wiring DO NOT force, bend, or pull wires. DO NOT damage wire insulation.
6 Warning Labels Below are representative warning labels and their location on the UPS. Exterior Handling labels shown in section 4.3, Transporting/Unpacking, are in the manual packet, and attached to the UPS shipping covering and shipping pallet. ATTENTION Make sure all the warning labels are installed in the appropriate locations. If a label is missing or illegible, contact Toshiba Customer Support Center or an authorized representative.

8.2 Transporting By Forklift Refer to Chapter 7 - Weight and Dimensions. Verify forklift maximum load capacity and ensure that the forks are long enough to properly support the UPS. Insert the forks into the space shown in Figure 8.6. Spaces for the forks are provided underneath the UPS. DO NOT swing or tilt UPS when lifting and/or transporting. Minimize the impact when lowering the UPS to the floor.
9 Storage/Operating Environment Observe the following when storing the UPS. • • • • • • • • • Store UPS indoors. Maximum storage time for the UPS between powered operation cycles is three years. If the UPS has been stored for a period exceeding 36 months, contact your factory authorized represnetative of guidance in starting the unit. Temperature fluctuations should be minimized. The optimal storage temperature range is 68 – 77 °F (20 – 25° C).
3) The UPS should not be used with a load that has a rated input that is greater than the rated output of the UPS. 4) If using the UPS to provide power to motors that require high starting current or with motors that require a long starting time, call Toshiba support for guidance in over sizing the UPS for lock rotor current. 5) DO NOT insert metal objects or combustible materials in the ventilation slots of the UPS. 6) DO NOT place, hang, or paste any objects on the exterior surfaces of the UPS.
9.2 Maintenance Precautions All internal maintenance sould be performed by factory authorized personnel. 1) Turn off, lockout, and tagout ALL power sources before connecting the power wiring to the equipment or when performing maintenance. 2) Hardwire type UPS units are not equipped with an over-current protection device, nor do they have an output disconnect for the AC output. A user-installed circuit breaker should be provided between the UPS output and the load input.
Caution DO NOT dispose of the batteries in a fire. The batteries may explode. DO NOT open or mutilate the batteries. Released electrolyte is harmful to the eyes and skin and could also be toxic. danger A battery can present a risk of electrical shock and high short circuit current. 9.3 Disposal Please contact your local or state environmental agency for details on disposal of electrical components and packaging in your particular area.
10 Installation warning Keep the SPECIFIED CLEARANCE around the UPS. Inadequate space around the UPS makes it difficult to perform maintenance/inspections, lead to insufficient ventilation, and/or will cause malfunctions. See Figure 10.1 - UPS Clearance DO NOT tilt the UPS more than 10° from upright position. Tilting the UPS more than 10° may cause crushing, trapping or other personal injuries. Install anchor bolts to secure the UPS to the installation floor.
10.1 Unpacking Unpack the UPS indoors on a paved floor. The UPS should be as close as possible to its final storage location. Overhead traveling cranes should be used to unpack any G8000 Series UPS. If an overhead traveling crane is not available, allow enough space for forklift operations to unpack the UPS crate. Then remove the crate. Points to observe 10.2 • Retain all small articles during unpacking and installation.
