Initial Startup and Electrical Checks 7.0 INITIAL STARTUP AND ELECTRICAL CHECKS Initial Startup and the Configuration Program—The UPS ships with a default 120 VAC L-N setting. This is also the most robust setting in that it can operate with either input phase angle (120 or 180 degrees). Perform initial system checks first. If the UPS configuration needs to be modified for your application, then go to the next section to review use of the configuration program.
Initial Startup and Electrical Checks 7.1 L14-30P Plug-in Connections—Including the PD-001 Distribution Box ! WARNING Miswiring power to the input (L1-L2-N-G) or connecting to single phase voltages (L-N-G only) may damage the UPS. A qualified electrician should verify that the L14-30R is properly wired before attaching the UPS. If the configuration program has been used to set the L-N voltage at 100, 110 or 115, then the input phase angle is required to be 180 degrees.
Configuration Program 8.0 CONFIGURATION PROGRAM The final step of installation may require custom configuration of your UPS using the enclosed configuration program. Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put into full time service powering the critical load. For most users operating with 120 VAC L-N and with no external batteries, the factory default settings will be adequate.
Configuration Program 8.2 Configuration Program—Installation An easy-to-use installation program will streamline the installation of the configuration program. If you have a previous version of this configuration program installed, it is recommended that it be uninstalled using its Uninstall program before installing this updated version. 1. Use the Windows Explorer to find and open the Lbt_gxt2-1.6.exe installation program on the included software CD. 2. When you see this PreSetup window, select OK.
Configuration Program 8.3 Establishing Communication Link with the UPS Use only the serial communication cable supplied with the configuration program. If an accessory communication card has been installed in the UPS’s communication card slot, the option card must be removed while using the configuration program.
