WIRING INSTRUCTIONS
PRECAUTIONS
• Do not run the temperature sensor wiring in any
conduit with line voltage (24/120/230 VAC) if
utilizing resistance temperature signal.
• Remove power before wiring. Never connect or
disconnect wiring with power applied.
• When using a shielded cable, ground the shield only
at the controller end. Grounding both ends can
cause a ground loop.
• It is recommended you use an isolated UL-listed
class 2 transformer when powering the unit with 24
VAC. Failure to wire the devices with the correct
polarity when sharing transformers may result in damage to any device powered by the shared transformer.
• If the 24 VDC or 24VAC power is shared with devices that have coils such as relays, solenoids, or other inductors,
each coil must have an MOV, DC/AC Transorb, Transient Voltage Suppressor (ACI Part: 142583), or diode placed
across the coil or inductor. The cathode, or banded side of the DC Transorb or diode, connects to the positive side
of the power supply. Without these snubbers, coils produce very large voltage spikes when de-energizing that
can cause malfunction or destruction of electronic circuits.
RELATIVE HUMIDITY WIRING INSTRUCTIONS
Open the cover of the enclosure. ACI recommends 16 to 26 AWG twisted pair wires or shielded cable for all transmitters. Twisted
pair may be used for 2-wire current output transmitters or 3-wire for voltage output. Refer to
FIGURE 5
(p. 3) for wiring diagrams.
TEMPERATURE WIRING INSTRUCTIONS
ACI recommends 16 to 26 AWG twisted pair wires or shielded cable for all temperature sensors. ACI recommends a separate
cable be pulled for Temperature signal only. Temperature Signal wiring must be run separate from low and high voltage
wires (24/120/230VAC). All ACI thermistors and RTD temperature sensors are both non-polarity and non-position sensitive.
All thermistor type units are supplied with (2) flying lead wires, and all RTD’s are supplied with (2) or (3) flying lead wires –
see
FIGURE 6
(p. 3). The number of wires needed depends on the application. Connect thermistor/RTD wire leads to control-
ler analog input wires using wire nuts, terminal blocks, or crimp style connectors. All wiring must comply with local and
National Electric Codes. After wiring, attach the cover to the enclosure.
