2.3 Frame Ground Connection
It is very important that the frame of the iPECS-MG System should be grounded:
1. Turn the grounding screw counter clockwise to loosen, as shown in Figure 2.3.
2. Insert the grounding wire and tighten the screw.
3. Then connect the grounding wire to an appropriate ground source (refer to Caution).
Figure 2.3 Grounding the KSU
CAUTION : 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).
2.4 External Backup Battery Installation
In case of power failure, the external backup batteries automatically maintain uninterrupted power for the iPECS-MG
System. The external batteries must provide 24V DC; this is generally accomplished by connecting two 12V batteries
in a series arrangement as shown:
Figure 2.4 External Backup Battery Installation
1. Connect the backup battery cable with 2 identical batteries (12V DC X 2).
2. Connect the external back up battery cable to the battery connector of the PSU.
3. After connecting the external backup battery cable, turn on the battery switch.
NOTE: The cable used to connect the battery is supplied with the KSU from the manufacturer.
