The indoor case has six 7/8" diameter knockouts for
3/4" conduit fittings. Three are located on the bottom of
the case and three on the back of the case. The three you
use will depend on whether you panel or wall mount the
enclosure.
To reduce the chance of noise on the signal input wires,
the input wires should be routed in separate conduit from
the power wiring.
Local regulations for proper grounding and connection
of the power to the recorder should be strictly followed.
The power wires are connected to the terminals located
on the inside back of the recorder. The AC voltage which
the recorder has been setup will be clearly marked near
the terminal strip.
Verify that you are connecting the proper
voltage to the recorder.
The terminal labeled H is the High
(black) wire, the terminal labeled N is the Neutral (white)
wire and the terminal labeled G is the Ground (green)
wire. The power wires from the terminal strip to the
circuit board are prewired at the factory.
The terminal blocks on the circuit board have snap on
connectors. To connect the input and output wires, pull
off the connectors from the terminal strips. Route the
signal wires through the flexible wiring raceway between
the back case and front door. Loosen the screws on the
connectors. Strip off about 1/4 inch of insulation from the
wires. Insert the wire into the proper connector and
tighten the screw securely. After connecting all of the
wires to the connector, snap the connector back on the
terminal strip.
The following section describes the proper connections
for the various transmitters that may be used with this
recorder and the connections for the relay outputs and the
4-20 mADC output.
There are three analog input channels and one
frequency input channel. The analog inputs will be setup
for a standard 4-20 mADC input signal unless otherwise
stated on the Data Sheet supplied with the manual. Three
different analog inputs can be connected to the three
analog input channels, but only the selected analog
channel can be recorded on the recorder.

The above wiring diagram shows the wiring
connections for current or voltage input signals. The Data
Sheet furnished in the front of this manual will indicate
the type of analog input for which your recorder was
setup. If this is different from the output of your
transmitter, contact the factory for corrective action.
