Introduction
This section contains general installation instructions for the Load Sharing Module. Environmental precautions and location considerations are included to determine the best location for the Load Sharing Module. Additional information includes unpacking instructions, electrical connections, and an installation checkout procedure.Unpacking
Before handling the Load Sharing Module, read page 4, Electrostatic Discharge Awareness. Be careful when unpacking the Load Sharing Module. Check the unit for signs of damage such as bent or dented panels, scratches, and loose or broken parts. Notify the shipper of any damage.Location Considerations
Consider these requirements when selecting the mounting location:* Adequate ventilation for cooling* Space for servicing and repair* Protection from direct exposure to water or to condensation-prone environment* Protection from high-voltage or high-current devices, or devices which produce electromagnetic interference* Protection from excessive vibration* An ambient operating temperature range of -40 to +70°C (-40 to +158°F)* All wiring to/from the Load Sharing Module should be limited to 30 m (98 ft) in length Do not mount the Load Sharing Module on the engine.Figure 1-2 is an outline drawing of the Load Sharing Module. Install the unit near the electromagnetic engine control. It may be installed in any position.To maintain compliance with CE marking requirements, the European Union Low Voltage Directive requires that the Load Sharing Module (LSM) be mounted in an IP43 enclosure as defined in EN60529. Access to the Load Sharing Module must be restricted to qualified personnel.General Wiring Requirements
The circled ground symbol identifies the Protective Earth Terminal. This terminal must be connected directly to protective earth using a grounding conductor at least as large as those used on terminals 1 through 9. The insulation of the grounding conductor must be of green and yellow color.
This symbol identifies functional or EMC earth. This terminal is to be used for cable shield connections only. It is not to be used as a protective earth terminal.External wiring connections and shielding requirements for a typical installation are shown in the plant wiring diagram. Figure 1-3. These wiring connections and shielding requirements are explained in more detail in this chapter.To maintain compliance with CE marking requirements, the Low Voltage Directive requires that the Load Sharing Module must only be connected to Class III equipment.Wiring for the Load Sharing Module must be suitable for at least 90°C (194°F) and also be suitable for the maximum installed operating temperature.The Load Sharing Module must be permanently connected and employ fuses or circuit breaker in each of the PT lines to limit current to LSM PT inputs to no more than 5 A. In addition, a 2 A fast-acting fuse or circuit breaker must be provided in the 24 Vdc power supply line.All terminal block screws must be tightened to 0.56 to 0.79 N m (5.0 to 7.0 lb-in).To maintain compliance with CE marking requirements, the EMC Directive requires that all shields be connected to the terminals provided per the plant wiring diagram, Figure 1-3.Wiring for the Load Sharing Module should not exceed 30 m (98 ft) in length.
