SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in this
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired. Do not use this unit to directly
command motors, valves, or other actuators not equipped with safeguards. To do
so can be potentially harmful to persons or equipment in the event of a fault to
the unit.
METER INSTALLATION
The PAX2A meets NEMA 4X/IP65 requirements when properly installed.
The unit is intended to be mounted into an enclosed panel. Prepare the panel
cutout to the dimensions shown. Remove the panel latch from the unit. Slide the
panel gasket over the rear of the unit to the back of the bezel. The unit should
be installed fully assembled. Insert the unit into the panel cutout.
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel latch
should be engaged in the farthest forward slot possible. To achieve a proper seal,
tighten the latch screws evenly until the unit is snug in the panel (Torque to
approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.
Installation Environment
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
SETTING THE JUMPERS
The PAX2A controller has four jumpers that must be checked and/or changed
prior to applying power. The following Jumper Selection Figures show an
enlargement of the jumper area.
To access the jumpers, remove the meter base from the case by firmly
squeezing and pulling back on the side rear finger tabs. This should lower the
latch below the case slot (which is located just in front of the finger tabs). It is
recommended to release the latch on one side, then start the other side latch.
Warning: Exposed line voltage exists on the circuit boards. Remove all
power to the meter and load circuits before accessing inside of the
meter.
INPUT RANGE JUMPERS
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
CAUTION:
Risk of electric shock.

POWER WIRING
The power supplied to the meter shall employ a 15 Amp UL
approved circuit breaker for AC input and a 1 Amp, 250 V UL
approved fuse for DC input. It shall be easily accessible and
marked as a disconnecting device to the installed unit. This device
is not directly intended for connection to the mains without a
reliable means to reduce transient over-voltages to 1500 V.

CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the controller application, the sensor input
common must be suitably isolated from hazardous live earth referenced voltages; or input common must be at protective earth ground potential. If not,
hazardous live voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the
potential of the user input common with respect to earth common; and the common of the isolated plug-in cards with respect to input common.

If not using User Inputs, then skip this section. User Input terminal does not need to be wired in order to
remain in the inactive state.
Sourcing Logic
(UACt Hi)
When the UACt parameter is programmed
to Hi, the user inputs of the controller are
internally pulled down to 0 V with 20
KWresistance. The input is active when
a voltage greater than 2.2 VDC is
applied.
