- Series 700HS 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 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. To
ensure accurate regulation, users should run two separate wires (twisted from the desired regulation points to
the remote sense terminals. Even if the load current is low, users should still connect +Vo to +S and –Vo to –S.
