    Safety instructions in this manual are supplementary to local safety instructions. Dale Power Solutions plc does not accept any liability caused as a result of failure to follow safety instructions. Please note the following: Do not use the UPS for any other purpose than the one for which it was designed.

  • Page 6: Conformity And Standards

    Conformity and standards This equipment complies with CE directives 73/23 & 93/68 (LV Safety) and 89/336 (EMC), and the following product standards for Uninterruptible Power System (UPS): IEC 62040-1-1 General and safety requirements for use in operator access area IEC 62040-2 EMC requirements; Class C3 compliant IEC 62040-3 Performance requirements and test methods Caution: Continued compliance requires installation in accordance with the instructions this manual and the use of manufacturer approved accessories only.

  • Page 8: System Block Diagram

    System block diagram The UPS is connected between the mains a.c. input source and the critical load to provide uninterruptible power free from disturbances on the mains supply such as voltage and frequency variations. This is achieved using high-frequency double-conversion pulse width modulation (PWM) and full digital signal processing (DSP) control.

  • Page 9: Battery Temperature Compensation

    Battery temperature compensation Using optional external battery temperature sensors the UPS is capable of optimising the battery charger output to enhance battery life and performance. This is a non-standard feature that must be purchased separately. Contact your distributor for details. Redundant control power supply board The UPS is equipped with two identical and fully redundant control power supply boards.

  • Page 10: Installation

    Installation Siting considerations Before unpacking and installing the unit, consider the following: DONOT expose the UPS to high temperatures, water ingress, flammable or corrosive gas, dust, direct sunlight or explosives. Locate the UPS indoors on a level surface as close as possible to the equipment it will be powering to minimise cable voltage drops.

  • Page 11: Units In Parallel

    Input Load MCCB (not MCB) Figure 2 Power cable wiring configuration for a single UPS Units in parallel A group of paralleled units behave as if it were one large UPS. To ensure units share the load equally and the system complies with relevant wiring regulations, follow these requirements: Use units of the same rating only and connect them to the same bypass source.

  • Page 12: Operation From A Generator

    Operation from a generator As a guide we recommend that the load capacity should be less than 30% of the generator capacity, and the generator rating should be 1.5 to 2 times the rating of the UPS, depending on the type of generator used.

    Mains breaker Power terminals Figure 3 E420, E430 and E440 internal layout Note: E460/E480 units are taller and the E480 is fitted with larger breakers and terminals in the lower part of the cabinet. Terminal and battery connections vary from those shown above.

  • Page 14: Wiring The Ups

    Wiring the UPS Before connecting the UPS, read the siting considerations above and check you have selected breakers and cables with the correct ratings. WARNING! BEFORE ATTEMPTING TO WIRE THE UPS ENSURE ALL BREAKERS ARE IN THE OFF POSITION AND WHERE POSSIBLE LOCKED OFF. Caution: DO NOT mix batteries from different manufacturers or mix different types of batteries.

  • Page 17: Wiring Units In Parallel

    Wiring units in parallel You can operate 2, 3 or 4 units in parallel. Caution: Each unit requires its own battery bank. You cannot use a common battery bank for more than one unit working in parallel mode. When operating units in parallel you must not use the built-in bypass as it is rated for one unit only.
  • Page 18 3. Below the black start switch on each UPS, remove the plate that covers the parallel connectors. 4. Connect the CAN bus, labelled Parallel Port 1 and Parallel Port 2, in a ring arrangement using the supplied cables as shown below. Make sure you wire all CAN bus connectors and secure them in place using their captive screw locks.

  • Page 19: Operation

    Operation Working modes The UPS has the following modes of operation: On-line mode Battery mode Auto-restart mode Bypass mode ECO mode Frequency converter mode Each operating mode is described below. On-Line mode This is the default mode of operation in which the load is supplied via the inverter when the a.c. input and load are within their normal ranges.

  • Page 20: Eco Mode

    ECO mode If specified, your UPS may be set to operate in ECO mode instead of on-line mode. In ECO mode the load is supplied via the bypass circuit and not the inverter, allowing the UPS to work at higher efficiency. The battery is trickle charged in this mode.

    5. Switch on the UPS main breaker. After a few seconds the Mains and Inverter LEDs are illuminated and the Bypass LED goes out (see Figure 9 on page 23). Note: If switching on into a transformer load, ensure the UPS is initially working in bypass mode before switching to on-line mode.

  • Page 30: Maintenance

    Maintenance At normal room ambient temperature the fans will operate continuously for 20,000 to 40,000 hours. Increased ambient temperatures will shorten this lifetime. Periodically ensure that air is blowing out of the rear of the unit. Battery We recommend the use of sealed lead acid, maintenance free batteries. Battery life depends on the ambient temperature and the number of discharge/charge cycles.
