4/17 Opening the Front Cover Open the Cord cover and turn the screws counter-clockwise to loosen as shown in Figure Lift the front cover in the direction of the arrow as shown

5/17 Before installation, assure that the AC plug is not connected to an AC outlet. The PSU is located at the left in the KSU and is pre-installed in the ipLDK-60 KSU. The PSU provides three DC voltage power sources to MBU through the 7-pin connector, CN7. Mains input: 100 ~230Vac Power Supply Unit Installation

6/17 Place the PSU cover on the PSU as shown in Figure. Then secure the PSU cover by tightening the screws (clockwise turn). Power Supply Unit Installation

7/17 Frame Ground Connection It is very important that the frame of the ipLDK-60 System is grounded: Turn the grounding screw counter clockwise to loosen, as shown in Figure. Insert the grounding wire and tighten the screw. Then connect the grounding wire to an appropriate ground source (refer to Caution). CAUTION The equipment should be connected to a socket-outlet with a protective ground connection. For ground wire, green-and-yellow insulation is required and the cross-sectional area of the conductor must be more than UL 1015 AWG#18 (1.0mm)). It is recommended that the ground wire is shorter than 1m (3.28ft). Proper grounding is very important to protect the ipLDK-60 from external noise or to reduce the risk of electrocution in the event of lightning strike. Be sure to comply with applicable local regulations.

8/17 The external batteries must provide 24V DC; this is generally accomplished by connecting two 12V batteries in a series arrangement as shown. External Backup Battery Installation NOTE The cable used to connect the battery is supplied with the KSU. CAUTION It is recommended to use an external backup battery fuse between the battery and the System. Recommended battery capacity is 24V/20AH MF; Carefully check the battery polarity with cable colors Red(+) and Blue(-) when connecting the battery to the System. Make sure that you do not short out the external batteries and cables. There is a danger of explosion if external batteries are incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer.

9/17 Expansion KSU to Basic KSU Connection Remove the dummy of each KSU. Use the link cable to connect the Basic KSU to the Expansion KSU. To fix the link cable securely, turn the screw clockwise to tighten and then tie the link cable with tie cable.
