    2.3 Inspecting and unpacking the UPS cabinet The UPS cabinet is palleted separately for shipping. The cabinet is shipped bolted to a wooden pallet and protected with outer protective packaging material (see Figure 3-8). CAUTION The UPS cabinet is heavy (see Table 2-1 on page 11). If unpacking instructions are not closely followed, the cabinet may tip and cause serious injury. Carefully inspect the outer packaging for evidence of damage during transit. CAUTION Do not install a damaged cabinet. Report any damage to the carrier and contact your service representative immediately.

    3 UPS system installation 3.1 Preliminary installation information WARNING Installation should be performed only by qualified personnel. Refer to the following while installing the UPS system: • Chapter 2 for cabinet dimensions, equipment weight, wiring and terminal data, and installation notes. • Do not tilt the cabinet more than ±10° during installation. • The landing plates are to be removed to add holes as required.
  • Page 22 CAUTION • Do not tilt cabinets more than 10° from vertical. • Lift the cabinet only with a forklift or damage may occur. NOTE For the following steps, verify that the forklift or pallet jack is rated to handle the weight of the cabinet (see Table 2-1 on page 11 for cabinet weight). If not already accomplished, use a forklift or pallet jack to move the cabinet to the installation area, or as close as possible, before unloading from the pallet. Insert the forklift or pallet jack forks from the right side of the cabinet, between the supports on the bottom of the pallet (see Figure 2-6 on page 13 for the UPS cabinet center of gravity measurements).

    3.4 Installing UPS external and battery power wiring NOTE The UPS cabinet is shipped with a debris shield covering the ventilation grill on top of the unit. Do not remove the debris shield until installation is complete. However, remove the shield before operating the UPS. Once the debris shield is removed, do not place objects on the ventilation grill. NOTE Remove the UPS cabinet top or bottom conduit landing plate to drill or punch conduit holes (see Figure 3-3). NOTE If the load requires a neutral, a bypass source neutral must be provided. If the load does not require a neutral and there is no neutral conductor connected at the bypass input, a neutral to ground bonding jumper must be installed. DO NOT install both a source neutral and a bonding jumper. See Table 2-4 on page 15 for neutral bonding jumper wire sizes. Bonding jumper must be copper wire. Use the procedures in the following paragraphs to connect the external and battery power wiring. 3.4.1 External power wiring installation To install wiring to connections: Remove one top screw and two bottom screws securing the UPS left front panel (see Figure 3-1).

  • Page 40: Understanding Ups Operation

    4 Understanding UPS operation 4.1 Looking inside the UPS system The Powerware 9395 UPS is a continuous-duty, solid-state, transformerless (at 400 Vac), three- phase, true online system that provides conditioned and uninterruptible AC power to the UPS system’s output and critical load. The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel, integrated communication server, and digital.

  • Page 41: Modes

    4.2 Modes The Powerware 9395 UPS supports a critical load in three different modes of operation. The UPS can automatically use all three modes, as required. The standard operation modes are: • In Normal mode, the critical load is supplied by the inverter, which derives its power from rectified utility AC power.

  • Page 42: Bypass Mode

    The inverter produces a three-phase AC output to a customer’s load without the use of a transformer. The inverter derives regulated DC from the rectifier and uses IGBT devices and pulse-width modulation (PWM) to produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output through the output contactor K3.

  • Page 43: Battery Mode

    In bypass mode, the output of the system is provided with three-phase AC power directly from the system input. While in this mode, the output of the system is not protected from voltage or frequency fluctuations or power outages from the source. Some power line filtering and spike protection is provided to the load but no active power conditioning or battery support is available to the output of the system in the bypass mode of operation.

  • Page 46 NOTE If installing, as part of the UPS system, a maintenance bypass without a rectifier input breaker, a minimum of two separate feeds with upstream feeder breakers, or one feed with two upstream feeder breakers, must be provided: one for the UPS and one for the maintenance bypass input. DO NOT use one feed or a single-feeder breaker to supply both the UPS and the maintenance bypass.

  • Page 47: Ups Operating Instructions

    5 UPS operating instructions This section describes how to operate the UPS. NOTE Before starting the UPS, ensure all installation tasks are complete and a preliminary startup has been performed by authorized service personnel. The preliminary startup verifies all electrical interconnections to ensure the installation was successful and the system operates properly. NOTE Read this section of the manual and have thorough knowledge of UPS operation before attempting to operate any of the controls. NOTE The UPS displays two minutes of battery runtime at the initial startup. After a 24-hour charging period, the UPS automatically runs a battery test and the correct battery runtime displays. 1027212 Revision B UPS 225 - 275 kVA User’s and Installation Guide...
