2.0 Safety and Preparation for Use

The configuration for the DC connector, if available, is as follows:
Pin 1 NC
Pin 2 NC
Pin 3 NC
Pin 4 +12 to +36 VDC power return
Pin 5 +12 to +36 VDC power
Pin 6 Chassis GND /Earth GND
Verify that the connector of the external DC power supply providing voltage to the unit has
the same pin configuration mentioned above. Do not apply AC voltage to the DC power
connector. Failure to follow these directions may cause injury or death to personnel, cause
irreparable damage to the instrument and voids all warranties.
Please note that the power return (pin 4) is NOT connected to the instrument case ground
internally, however both ground connections (pin 4 and pin 6) are available at the DC
power connector and may be connected together at this point.
The following specifications should be used to ensure optimum performance:
DC Supply voltage
+12 to +36 VDC, 2 Amps
Line regulation
+/- 0.05% for a 10% line change
Load regulation
+/- 0.05% for a 50% load change
Output ripple
< 5 mV peak-to-peak
Detaching the DC power cord is the only option of disconnecting the unit from the DC
mains supply. Make sure you have access to the rear panel or provide an external
accessible DC disconnect means for your PPS-2RM-B.
