2.4 GROUNDING THE KSU (Figure 2-2)

DCS-816 comes equipped ready to use with the third wire AC ground provided through the power

cord. This ground will be adequate for most applications. However, if it is suspected that there is

a problem with the ground provided at the 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 grounding lug on the KSU must be connected to a ground rod or metal cold water

pipe using #10 AWG (approximately 2.6 mm in diameter) solid copper wire. (See Figure 2-2.)

Failure to provide an adequate ground may cause unpredictable operation or even circuit 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.

2.5 MDF CABLING (Figure 2-3)

All connections to the DCS-816 system are made via a customer–provided main distribution frame

(MDF) and the cables can be routed into the KSU cabinet from below.

A 25-pair male champ connector and a 4-pair modular jack (RJ-45) on the base board are

prepared for external connections. The connections for SLTs are made through the RJ-45

modular jack and other connections are made through the champ connector. The detailed pin

assignments are as follows. (Note that the colour of wires may be differently specified in some

countries.)
