PRIOR TO INSTALLATION
1. Read these installation instructions and manual prior
to beginning installation.
2. Install this device only if you are a qualified electrician
trained to perform such work.
3. Before beginning installation, lay out the system
components, the heat trace cable and the
temperature probe in their approximate locations to
visualize the system and evaluate exact component
and junction box placement, as well as required
cable and conduit lengths.
INSTALLATION
The GPT 230 Automatic Heat–Trace Control should be
installed by a qualified , licensed electrician . Installation
must conform to all applicable local and national
electrical codes and laws . The unit ’s NEMA 4X IP66
enclosure allows for indoor or outdoor applications.
The GPT 230 controller has an ambient operating
temperature range of −40 °F to 131 °F (−40 °C to 55 °C).
To avoid potential internal condensation mount the unit
out of direct sunlight.
Install the GPT on a fixed, flat, vertical surface using
the unit’s mounting flanges. The mounting flanges
accommodate 1/4” or 6.3 mm fasteners.
The GPT 230’s nonmetallic enclosure has one 1.046” hole
for conduit entry; this can hold both power and load wiring
.
Use only Listed Type 4X IP66 liquid–tight conduit hubs
or cable glands. Connect the hub to the conduit system
before connecting the hub to the enclosure.
The unit comes with two installed liquid–tight cable
glands. One of these fittings is for the temperature sensor
cable, and the other is for the alarm relay cable.
The cable glands can accommodate cable diameters
0.08” to 0.24” (2 mm to 6 mm). The temperature sensor
may be located up to 2,000’ (610m) from the GPT.
There is a removable electrical insulation divider that
must be in place when there is power applied to the unit.
All leads should be terminated; no unsecured leads
should be left inside the wiring compartment.
