Mounting
Mount controller into 92 mm (3-5/8") square cutout (1/4-DIN). See Figure 1 for cutout and case dimensions.
The plug-in controller does not have to be removed from its housing for mounting.
Measurements

reduced if the controller is to be mounted in an extra thick panel. If the controller has been unplugged from
its housing, the top of the housing can be determined by the serial number tag.

Power Wiring
Circuits
When properly installed through a NEMA enclosure, the integrity of the enclosure will be maintained and will remain "Watertight."
IMPORTANT: All electrical wiring connections should be made only by trained personnel, and in strict
accordance with the National Electrical Code and local regulations.
The Series 2000 controller has built-in circuitry to reduce the effects of electrical noise (RFI) from various
sources. However, power and signal wires should always be kept separate. We recommend separating
connecting wires into bundles: power; signal; alarms; and outputs. These bundles should then be routed
through individual conduits. Shielded sensor cables should always be terminated at one end only.
If additional RFI attenuation is required, noise suppression devices such as an R.C. snubber at the external
noise source may be used. If you wish, you may order this suppressor directly from Athena, part number
235Z005U01.
Consult serial tag on the unit and select power wiring diagram for the model specified. All wires are connect-
ed to the terminals on the back of the case. Screw terminals are provided. Make appropriate connections
using proper size wire for rated controller load power circuits. (On -B output model, use AWG #14 wire; for
-F, -S and -T outputs use #14, 16, or 18 wire.) The unit can be supplied with 120 V or 240 Vac, 50/60 Hz.
Select proper terminal for the voltage used.
