Switches On The Control Board - HP E1135C Operating And Service Manual

PRODUCT DESCRIPTION

Switches on the Control Board

The Voltage Selector Switch (S1) sets the operating voltage of the power supply on the
Control Board. It does NOT set the PDU for the mains configuration; that is done by the mains
connection and a jumper on the input terminals on the Mains Disconnect Switch.
If S1 is incorrectly set to the 115V position and high mains voltage is applied, the Control
Board will interpret it as a high-line condition and light the Line/EMO Error Indicator. If S1 is
incorrectly set to the 230V position and low mains voltage is applied, the Control Board will
interpret it as a low-line condition and light the Line/EMO Error Indicator. In both cases, there
will be no damage to the PDU, and the outputs of the PDU cannot be turned on (enabled).
The Main/Branch Switch (S2) sets the PDU to be either a "main" PDU or a "branch" PDU.
These functions are described on page 18.
