2-12 BOP HIPWR 111315NOTE REGARDLESS OF OUTPUT CONFIGURATION, EITHER LOCAL OR REMOTE OUT-PUT SENSE LINES MUST BE CONNECTED FOR OPERATION.1. OBSERVE POLARITIES: The OUT S sensing wire must be connected to the OUT-PUT load wire, and the COM S sensing wire must be connected to the COMMON loadwire.2. IF LOCAL SENSING IS USED, INSTALL LINKS (see Figure 2-3).CAUTION: The safety features incorporated into the BOP to handle energy from Activeloads are unable to protect the power supply or the load if input power to theBOP is lost or if the BOP malfunctions. It is recommended that the user mon-itor “Power OK” flag pins 3 and 4 of the external Protect Port (see Table 2-4)and implement a fast-acting means of disconnecting capacitive loads orcrowbarring inductive loads to prevent damage to both the BOP and the loadin the event of input power loss.2.5.6 LOAD CONNECTION USING LOCAL SENSINGFigure 2-3 shows a typical configuration using local sensing and a grounded load; for localsensing with an isolated (“floating”) load, do not install the ground connection (see Figure 2-3,Note 2).2.5.7 LOAD CONNECTION USING REMOTE SENSINGFigure 2-4 shows a typical configuration using remote sensing and a grounded load; for remotesensing with an isolated (“floating”) load, do not install the ground connection (see Figure. 2-4,Note 2). Use #22 AWG wire, twisted pair for remote sense connections.2.6 COOLINGThe power devices used within the power supply are maintained within their operating tempera-ture range by means of internal heat sink assemblies and by two cooling fans. Periodic cleaningof the power supply interior is recommended. If the power supply is located within a confinedspace, take care that the ambient temperature, which is the temperature of the air immediatelysurrounding the power supply, does not rise above the specified limits (see Table 1-2).2.7 SETTING UP THE UNITThe following paragraphs describe the connections and initial BOP setup needed to operate inthe desired mode.2.7.1 CONSIDER THE LOAD TYPEThe BOP can be configured to respond differently to the Output OFF command, depending onwhether the load is defined as Active, Resistive or Battery. Refer to PAR. 3.3.6 to configure thissetting.
