Prior to mounting the Series C in your panel, make sure that the cutout opening is of the right size, 1.771” x 1.771” (45 mm x 45 mm),
and deburred to enable a smooth fit. A minimum of 4” (100 mm) of depth behind the panel is required.
Unpacking and Inspection
1. Inspect shipping carton for obvious signs of mishandling.
2. After removing the controller from the shipping carton, inspect it carefully for damage. Never attempt to install and use a damaged
unit.
3. Verify that the ordering code number indicated on the side of the controller matches what was ordered.

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 C 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.
Figure 4. Contact Identification
Make sure that you are using the appropriate thermocouple and extension wire. Connect the negative lead
(generally colored red in ISA-type thermocouples) to contact #9; connect the positive lead to contact #10.
Extension wires must be the same polarity as the thermocouple.
Figure 5. Thermocouple Input Wiring
Note: For 2-Wire RTD
Jumper 8 & 10
The Series C accepts input from 2- or 3-wire, 100 ohm platinum resistance temperaure detectors (RTDs).
Connect 2-wire RTDs to contacts #9 and #10, with a jumper across contacts #8 and #10. Keep leads short and
use heavy gauge copper extension wire, if necessary, to minimize lead resistance. For long runs, 3-wire RTDs
should be used.
Figure 6. RTD Wiring

Voltage Inputs: Connect the positive voltage input to contact #10; the negative
input to contact #9.
Current Inputs: Connect the positive current input to contact #10; the negative
input to contact #9.
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 #11,
with a 2AG, 0.5 amp rated fuse. It is recommended that instrument power and load power
be fused independently.
