Voltage Inputs: Connect the positive voltage input to contact #20; the
negative input to contact #19.
Current Inputs: Connect the positive current input to contact #20; the
negative input to contact #19.
Figure 7. Process and Linear Input Wiring
The Series C power supply accepts 100 to 250 Vac and 100 to 250
Vdc line power without any switch settings or polarity considerations.
All connections should be made in accordance with the National
Electrical Code and local regulations, using only NEC Class 1 wiring
for all power terminals.
It is advisable, but not necessary, to fuse one leg of the incoming
power line, contact #9 or #10, with a 2AG, 0.5 amp rated fuse. It is
recommended that only instrument power is fused - not power to the
load.
