You must read this manual before installation, use or work on the product.
This product contains dangerous voltage that when touched can cause electric shock, burns
or death.
The product must be installed by qualified personnel and according to the installation
instructions. Service may only be performed by authorised service personnel. The equipment
may only be opened by qualified personnel. Work in addition to replacing the rectifier modules
may only be carried out when all power has been cut to the equipment and when the mains
breaker has been closed for at least five minutes. The protective covers and contact safety
devices inside the equipment may only be removed by authorised service personnel.
The power must always be disconnected in a safe way before starting any
service/maintenance.
WARNING! Multiple power sources. Dangerous voltage is possible even with mains power
shut off. The panel mains power switch does not give a dead condition.

  • Page 5: Presentation

    PRESENTATION PRX is a family of charging rectifiers in single phase configuration with integrated monitoring that are designed for wall mounting. The charging rectifier is constructed using plug-in rectifier modules for simple maintenance and high flexibility and availability. Its compact design allows it to be used even in confined spaces.

  • Page 9: Functional Description

    FUNCTIONAL DESCRIPTION GENERAL PRX is a complete rectifier with integrated monitoring. Most functions are handled by the monitoring unit and are described in the Manual for monitoring unit PCM2. Only the functions that feature at a general rectifier level are described here.

  • Page 10: I/O Unit

    I/O UNIT The I/O unit contains an adapter for the external connections required for the monitoring unit. It is fitted directly on the back plate together with the terminal blocks for AC input and DC output. FUNCTIONS 4.5.1 General Only the most important functions are specified here. For more information, see the Manual for monitoring unit PCM2.

  • Page 11: Operation

    OPERATION GENERAL The bulk of the operation is associated to the monitoring unit. This is described in the Manual for monitoring unit PCM2. Other operation is detailed in this section. MAINS FEED The mains breaker handles the mains feed to the rectifier modules. Note that the breaker only cuts the mains feed to the rectifier modules.

  • Page 12: Voltmeter Terminals

    The modules are of the “plug-in” type and can in principle be replaced during operation. For more information, see the INSTALLATION INSTRUCTIONS section. VOLTMETER TERMINALS When measuring the battery voltage you should avoid measuring directly at the battery terminals due to the risk of arcing in the event of a possible short circuit. Use the short-circuit protected voltmeter terminal on the front panel instead.

  • Page 13: Installation Instructions

    INSTALLATION INSTRUCTIONS SAFETY INSTRUCTIONS WARNING! This product contains dangerous voltage that when touched can cause electric shock, burns or death. Protective earth must always be connected in a reliable way to avoid the risk of live parts in the equipment in the event of faults. No live parts are permitted during installation. The product must be installed by qualified personnel (see 2 SAFETY INSTRUCTIONS) section.

  • Page 14: Electrical Installation

    ELECTRICAL INSTALLATION 6.5.1 General The equipment is designed for permanent installation. Protective earth must be connected before any other installation. For cable inlets there are six “knock-out” holes of which two has a diameter of 32.5 mm designed for fitting type M32 and five with a diameter of 20.5 mm designed for fitting type M20.

  • Page 15: Rectifier Modules

    Ensure that there is an external fuse to the battery. 6.5.5 Rectifier modules The rectifier modules are normally packed separately and are to be put in place during the installation. The rack module slots should be equipped with modules starting from the leftmost position and with spare slots to the right.

  • Page 16: Battery Temperature Measurement (Option)

    6.5.9 Battery temperature measurement (option) Measurement of the battery temperature is done via an enclosed Pt-1000 sensor. It is used both to monitor the temperature level and for temperature control of the float charging voltage. As the sensor is a Pt-1000 model, bipolar measurement is sufficient, as opposed to the more common Pt-100 which often needs four-pole measurement to ensure that conductor resistance does not impact negatively on the measurement results.

  • Page 17: Commissioning

    COMMISSIONING SAFETY INSTRUCTIONS WARNING! This product contains dangerous voltage that when touched can cause electric shock, burns or death. All contact safety devices must be fitted during operation. PREPERATORY INSPECTION Check that the equipment is free from damage, correctly fitted and that all the ventilation openings are free from obstacles.

  • Page 18: Check Of Charging Voltage

    initial equalizing charge. Always follow the recommendations given by the battery manufacturer. CHECK OF CHARGING VOLTAGE Check the settings of the monitoring units to ensure the voltage level for float charging and equalizing charging conform to the battery manufacturer's specifications, see Manual for monitoring unit PCM2.

  • Page 19: Maintenance

    MAINTENANCE ANNUAL INSPECTION 8.1.1 General In addition to these instructions, you must observe the instructions for maintenance in the Manual for monitoring unit PCM2 and the battery manufacturer's maintenance instructions. 8.1.2 Check of charging voltage Connect a measuring instrument to the voltmeter terminal (see section 5.5 VOLTMETER TERMINAL).
