1 PRODUCT DESCRIPTION 1.1 GETTING STARTED
The following procedure describes how to unpack and setup the DGP.
1. Unpack and examine the DGP Digital Generator Protection relay. Ensure each module is properly seated
in the relay prior to applying power.
2. Apply rated DC power to the relay at the power supply input terminals. Refer to the appropriate elementary
diagram in Section 1.5: ELEMENTARY DIAGRAMS on page 1–23 for the location of these terminals. The
rated DC value (Vps) for the relay is found on the nameplate located inside the front cover on the right
side.
3. The DGP settings and control functions are protected by passwords on both MMI and remote access. The
relay is shipped with the factory default passwords that must be changed before any setting change or
control command can be executed (GE Modem Version only). The default passwords are listed below:
MODE
MMI - SETTING
MMI - MASTER
REMOTE LINK - VIEW
REMOTE LINK - SETTING
REMOTE LINK - CONTROL
Note that the characters "." and "!" are part of the default passwords.
4. Instructions on how to use the keypad to change settings and put the relay into test mode can be found in
Section 4.3.2: SETTING CHANGES on page 4–3. Complete instructions on how to operate the keypad are
found in Section 8.3: KEYPAD on page 8–3.
5. To communicate with the relay from a PC, connect the relay to a serial port of an IBM compatible computer
with a DGP null-modem cable. Connection can be made either to the 25 pin D-connector on the back of
the relay (PL-1) or the 9 pin D-connector on the front (COM).
6. Refer to Figure 9–1: DGP COMMUNICATIONS WIRING on page 9–3 for the internal wiring of the cable.

Power Management Products CD or available from the GE Power Management web site at www.ge.com/
indsys/pm. Follow instructions in 10.1.3: INSTALLATION on page 10–1 to load GE-Link onto the PC.
