Input Power Connections -
Be certain to connect the pump to the proper supply voltage. Using the incorrect voltage will damage
the pump and may result in injury. The voltage requirement is printed on the pump serial label.
Jumper pins on the circuit board are factory preset for the correct voltage. See Fig. 4.4, page 7 for
details.
The A-100NV is supplied with a ground wire conductor and a grounding type attachment plug (power
cord). To reduce the risk of electric shock, be certain that the power cord is connected only to a properly
grounded, grounding type receptacle.
Note:
When in doubt regarding your electrical installation, contact a licensed electrician.

External Input Signal Connections -
The A-100NV will accept any one of three different types of external input signals; 4-20 mA, 0-10
VDC, or frequency. Two types of frequency inputs, AC sine waves (magnetic coils type outputs) and
Digital Square waves (Hall Effect signals, contact closures), are acceptable. A jumper plug located on
the circuit board is factory pre-set for AC sine wave signals, the jumper must be re-positioned when
digital square wave signals are being used. (See Fig. 4.4, page 7, “Hz input jumper settings”)
All wiring connections are to be made inside of the junction box located on the side of the A-100NV. A
liquid-tite connector is supplied and should be used for the external signal cable. The signal input wires
are color coded to the type of signal being used.
