DCS Compact II INSTALLATION MANUAL

2.6 Grounding

2.7 MDF Cabling

DCS Compact II comes equipped ready to use with a third wire AC ground
provided through the power cord. This third ground will be adequate for most
applications. However, if it is suspected that there is a problem with the ground
provided at AC outlet or local codes require a solid earth ground to be connected
to the KSU, the existing third wire ground must be disconnected before power is
applied. The existing third wire ground is disconnected by removing the holding
screw and tapping and storing the wire. After this wire has been disconnected,
the grounding lug on the PSU(Power Supply Unit) must be connected to a
ground rod or metal cold water pipe using #10 AWG solid copper wire.
Failure to provide an adequate ground may cause unpredictable operation or even
circuit card failure.
WARNING
Unplug the power cord from the AC outlet before attempting to connect the ground.
Hazardous voltage may cause death or injury. Observe extreme caution when working
with AC power.
All connections to the DCS Compact II system are made by way of a customer-
provided main distribution frame (MDF). The KSU and expansion kit are each
connected to the MDF using a 25 pair female amphenol-type cable . These cables
can be routed into the KSU cabinet from below. (See Figure 2-5 & 2-6)
Label each cable to correspond with the connector number. Label each 66
terminating block with the same connector number with which the cable is
labelled.
Use one pair twisted wire to cross-connect stations or lines to their associated
port.
