SC300 System Controller
The SC300 system controller is an advanced control and monitoring solution which provides a full
suite of communications options, including built-in Ethernet interface, Web server, Modbus, and
SNMP agent.
Alarm notifications may be by Email, SNMP traps, SMS text messaging, dial-out to
PowerManagerII remote monitoring software, or relay contact closures.
1. Power on LED (green)
2. Minor alarm LED (yellow)
3. Critical/Major alarm LED (red)
4. Color LCD
5. Soft keys (2)
6. Navigation keys (4)
7. Micro USB type AB
connector
8. Retaining screw
9. Power and system
communications connector
10. RS-232 / RS-485 connector
(RS-485 some versions only)
11. Ethernet connector
(100baseT) and status LEDs
The SC300 is supplied pre-configured with either a default configuration file, or with one factory
customized for a particular application. Some configuration file changes can be made with the
keypad, or all settings can be changed via a PC connected to the SC300 through a network or the
USB interface (see details on page 23).
For connector pin-outs see details on page 137. See Troubleshooting on page 122 for details of
SC300 alarm LEDs.

Sensors: Current - 3, Bus voltage - 1, Temperature - 2, Battery Mid-point - 4
Input/Output: Digital inputs: 4 pre-defined system functions, 6 / 9 user-defined
Relay outputs: 6/8/10 (one also used as Monitor OK alarm)
LVD contactor outputs: 2 or 3
For input and output specifications see details on page 129. For connector pin-outs see details on
page 138.
IO Board options include:
IOBGP-00
Uncased, 2 x LVD, 6 x relay, 6 x user DI
IOBGP-01 Cased, 2 x LVD, 6 x relay, 6 x user DI
IOBGP-10 Uncased, 3 x LVD, 10 x relay, 9 x user DI

Changing a Configuration Setting using the Keypad
For the configuration settings that can be changed using the keypad, the keys have the following
functions.
Press to change the setting or activate a control process.
Press to change the value. Hold key to change at a faster rate.
Use these keys for values with multiple segments (for example an IP address).
Press to save the new value.
Or
Press to leave the value unchanged.
Keypad Access Security
This feature prevents accidental or unauthorized changes to settings from the SC300 keypad.
All access to change an SC300's settings will be lost if:
•All communications are disabled (see S3P Access on page 116 and HTTP/HTTPS
Access on page 117), and
•Keypad access is Read Only, or PIN Protected and the keypad access PIN is lost.
The SC300 will continue to function, but no configuration changes can be made.
Contact your Eaton dc product supplier or Eaton for advice (see Worldwide Support
on page 153).
►To use Web / DCTools to enable/disable keypad access
•In Web go to System > Interfaces > Front Panel.
•In DCTools, go to Configuration > Communications > Front Panel.
•Set Access to:
•Unprotected - keypad access is allowed to view and change parameters, or
•Read Only - keypad access is allowed to view parameters only, or
•PIN Protected - keypad access is allowed to view and change parameters if the
correct 4-digit number is typed in the Access PIN field. Otherwise, Read Only
access is allowed.
►To use the SC300 when access is set to PIN Protected
•At the Main Screen press Menu. The Logon screen appears.
•If the Access PIN is not known then press Skip to use the SC300 with Read Only access.
•If the Access PIN is known:
•Use the Left and Right keys to access each digit position. Use the Up and Down
keys to change the digits.
•When the correct digits are entered, press Logon.
Keypad access will return to PIN Protected mode when the display returns to the Main Screen.
