Enclosure Mounting
Select a mounting location allowing unencumbered and convenient access to the controller. The controller should be mounted in
a location without direct exposure to sunlight. Loosen the four (4) large plastic cover screws and carefully remove the cover.
Unplug the interconnect wire harness from the Power/Relay circuit board located in the enclosure base. Allow the cover to hang
from the sensor wires while mounting the enclosure. Be careful not to damage the sealing edge of the enclosure walls. Mount
the controller to a flat vertical surface using four (4) suitable #8 stainless-steel screws (not supplied). Use the existing enclosure
mounting holes, which are external to the equipment cavity and located under the large cover screw threaded holes at each
corner.
Conduit Hubs and Fittings
The controller is supplied with hole suitable for a ½" conduit fitting. A conduit hub or fitting designated as type 4X "Liquid Tight"
must be utilized in order to maintain the watertight integrity of the enclosure. Conduit hubs must be connected to the conduit
before the hub is connected to the enclosure. Under no circumstances can low voltage (network/sensor) wiring and line voltage
control wiring be combined inside the same conduit.
Caution:
Use of grounding hubs and jumper wires is required.
Control Wiring
Loosen the four (4) large plastic cover screws and carefully remove the cover. If not done so already, unplug the interconnect
wire harness from the Power/Relay circuit board located in the enclosure base. Allow the cover to hang from the sensor wires
while the control wiring is being done. Be careful not to damage the sealing edge of the enclosure walls. All of the line voltage
wiring is done to the Power/Relay circuit board located in the enclosure base.
All wiring should be performed by a qualified electrician following the National Electric Code and local regulations. Use stranded
copper conductors only. The total electrical load must not exceed the rating of the controller (see specifications). Twenty (20)
ampere maximum branch circuit protection is required for both the controller power and relay contact circuits. The relay contact
circuit can be combined with or be independent of the controller power circuit. Multiple TC-2000 controllers may share power and
relay circuits.
This enclosure is non-metallic and does NOT provide a grounding means between conduit connections.
