 INSTALLATION

CONTENTS OF THE BOX Inside the box you should find:

• 1x Apex MCS Microgrid controller
• 1x Connection diagram

1. TOOLS REQUIRED

   • Appropriate tool for your choice of fastener to secure the MCS to the selected surface.
   • Flat screwdriver no wider than 2mm.
   • Laptop and network cable for troubleshooting.

2. PLANNING THE INSTALLATION

   • LOCATION
     The Apex MCS may only be installed indoors and must be protected from moisture, excessive dust, corrosion and humidity. It should never be installed in any location where a potential water leak could occur.

   • MOUNTING THE MCS
     The MCS enclosure provides four mounting tabs with holes of 4mm diameter for your choice of mounting screws or bolts. The MCS should be fixed onto a firm surface.

   • WIRING OF THE MCS
     Each side of the MCS has a row of connectors. These are used for connecting both the measurement signals and the communications, as follows:

   •   METERING:
     A full onboard power meter is included. The meter can measure 3 currents using 5A secondary CTs and can measure 3 mains AC voltages.

   • DEVICE POWER:
     The MCS is powered from 230V via the “Voltage L1” and “Neutral” terminals on the right side of the device (see image above). Commonly available 1.5mm² is recommended.

   • CAN BUS:
     The device is fitted with 1 CAN interface and is designed to communicate with compatible sub components in the system via CAN bus. It can be terminated by bridging the CAN H and TERM pins.

   • NETWORK:
     The device can connect to a standard 100 base-T Ethernet network for communication with MODBUS TCP equipped slave devices and for remote system monitoring, using a standard RJ45 connector.
     For remote monitoring, the network requires transparent internet connectivity and a DHCP server.

   • RS485:
     For field equipment requiring Modbus RS485 communications, the MCS is equipped with 1 RS485 interface. This port is terminated using an onboard jumper, so the device should be installed at the end of the bus. If a different configuration cannot be avoided, please contact support to guide you through removal of the jumper.

   • I/O:
     Terminals on the left side of the device provide programmable I/O interfaces. These interfaces are used where binary input or output signals are required. 5 inputs and 4 volt-free relay contacts are provided as outputs.

   • COMMUNICATIONS WIRING:
     RS485 and CAN connections must be done with a high quality shielded twisted pair communications cable.

Please follow this diagram to ensure that your RS485 and CAN busses are correctly laid out and terminated.

COMMISSIONING AND OPERATION

• POWERING UP FOR THE FIRST TIME
  • Check your work.
  • Ensure the device is connected to internet via ethernet.
  • Check that all DIP switches are set to 0, except DIP switch 1 must be set to 1.
  • Apply power.

STARTUP SEQUENCE
On first start-up, you should see the following sequence on the MCS screen. Wait for it to complete. MLT logo appears.
The system logs in automatically.

UI loads.

The MCS requires our engineers to configure the device for you, once it has been connected into your site and has a transparent internet connection. With this in place, you may now proceed to commission with remote support from Rubicon. When ready, please contact the Rubicon engineer assigned to your project.

CLEANING AND MAINTENANCE

• Cleaning and maintenance should only be carried out with the Apex MCS disconnected from any supplies.
• Before taking any action, make sure that the system has been correctly isolated by opening the electrical isolators. To clean the MCS, wipe the exterior surface with a damp (not wet) soft, non-abrasive cloth. Pay attention to the cooling slots and any dust build-up thereon which may affect the ability of the MCS to dissipate heat generated.
• Do not try to repair the device yourself in case of any malfunction. If the need arises, contact Apex customer service. The system does not require any special maintenance, except for standard physical cleaning to ensure good air flow and the maintenance required by any electrical device connected with terminals that need to be tightened.
