I Introduction After removing the unit from its packaging and ensuring that it has suffered no damage in shipment, it is important to read this manual and follow its instructions to ensure proper connection and mounting. 600HS Series models are fully isolated dc-dc converters capable of delivering up to 450 Watts in extreme ambient temperatures and adverse operating conditions. See specification sheets at the end of this manual for the ratings of a particular model. II Installation 2.
Figure 2 All dimensions are in inches III Regulation With Remote Sense Pin G +Vo + A HS DC-DC Converter +S Load C -S twisted pair Figure 3 I -Vo The HS Series provides regulated outputs at the output terminals. When there is a large current and/or the output cable is of some length, the voltage at the end of the cable may be noticeably lower than at the terminals. The converter can compensate up to 0.75V of voltage drop through remote sense terminals.
IV User Adjustments Series 600HS units are gasket-sealed. Changes or adjustments to the operating modes of any unit are accomplished internally: 1) To gain access, (Disconnect power from the unit before opening) remove the 5 outer black hexagonal head screws retaining the connector plate as shown in Figure #4. Then remove the 4 screws surrounding the connector. This will enable the removal of the front panel. Figure 4 2) After removing the screws, lift the panel to expose the internal components as shown.
D) Fuse Replacement: In the unlikely event that fuses F1,2 will open, disabling the unit, DO NOT CHANGE FUSES WITH THE POWER APPLIED. In order to restore normal operation, the user will need to ensure that the cause of the failure has been removed. Then the blown fuses need to be removed by gently prying them out of their clips and replacing them with ones of identical ratings. Notwithstanding the above the user should take every precaution to ensure that a reversed polarity input is avoided.
