Chapter 5 - Installation
1.
If rack mounting, attach the mounting ears to both sides of the DS-100
using the enclosed screws. Unit will fit in either a 19" or 23" rack and can be
flush or center mounted.
2.
Position unit into rack, aligning mounting ear holes with rack holes.
Secure unit into place by affixing screws with corresponding washers.
3.
To power the modem (not ncluded) from the DS-100, insert the bayonet
end of the modem power cable into the modem. Assuming your modem
operates off 12 VDC, insert the ribbed or marked lead into the “+12V” termi-
nal. (You may want to test the polarity of the modem power leads before
connecting.) Insert the other lead into the ground terminal marked, “GND”.
Fiber optic isolators normally used the +12 VDC and -12 VDC connections.
*NOTE* The -12 VDC connection is NOT recommended for powering modem
installations.
4.
Connect the modem to the DS-100 by attaching a DB-25 male to DB-9
female RS- 232 cable, not included, to the DB-9 male Modem port on the
back of the unit.
5.
Attach an RJ-11 modular cable between the modem and the PSTN or
communications device. (i.e. SLSS, CIUS or phone line.)
6.
Connect a DB-9 male RS-232 cable, not included, into one of the User
ports. (Figure 6 depicts connections to User ports 1 and 2.) Connect the
other end of the cable’s DB-9 female connector to your IED. Connect the
remaining User ports to other IEDs in a similar fashion.
7.
Remove the yellow terminal block cover and apply power to the DS-100
by connecting the power cable from your substation power source (42-150
VDC or 90-120 VAC at 60 Hz) to the unit’s power terminals marked “+” and
“-”. When connecting to DC power, make sure you connect the “+” power
cable lead to the “+” terminal and the “-” power cable lead to the “-” terminal.
Next, connect the chassis ground marked “GND” as specified by local
practices. Replace terminal block cover when finished.
8.
If the user wants to utilize the Emergency Interrupt feature, connect wire
leads into the Emergency Interrupt terminals. Connect the other wire end to a
switched AC or DC power source. (The Teltone SLSS auxiliary relay may be
used for this application.)
9.
If the user wants to utilize the Remote Alarm feature, connect wire leads
to terminal connections marked “ALRMS”. The alarm contacts close during
an alarm.
10. Connect a terminal or PC, loaded with a communications software
program to the Local Maintenance port located on the front of the unit using
a DB-25F to DB-9M adapter (if required) and a DB-9F to DB-9M RS-232
cable (not included).
11. Open the communication software program. Set the communication port
to match the DS-100 Factory Default settings (unless you have changed
them.)
