PREPARATION AND SYSTEM SET-UP
With system circuit breaker off, install the power cable, heater cable, temperature
probe, alarm relay, and conduit. Refer to Figures 2, 3, and 4, as well as Table 1.
Remove the clear plastic unit cover and face plate to access the inside of the
unit. Replace the clear plastic cover and face plate following installation.
INSTALLING THE POWER CABLE
Install the power cable as shown in Figure 2 and described in Table 1.
INSTALLING THE HEATER CABLES
Install the heater cables in accordance with National Electrical Code (NEC) and
manufacturers’ requirements, as well as other applicable codes. Properly seal
and waterproof all cable runs. Position the heater cable so it does not interfere
with the temperature probe. Never touch the ends of the yellow leads or let the
yellow leads contact each other or any component inside the control box once
power is applied. Upon conclusion of heater cable installation, perform a Mega-
Ohm or “megger” test on the heater cables as directed by the heater cable
manufacturer. Record results on page 2 and retain for future reference.
INSTALLING THE TEMPERATURE PROBE
Install the sensor end of the temperature probe as desired for the intended
function. Route the temperature probe through conduit or through the weather-
tight connection port on the control. Connect both temperature probe leads to
the Temp Probe terminals on the PC board. Refer to Figure 3.
INSTALLING THE ALARM RELAY
Install the alarm relay as shown in Figures 2 and 3 and described in Table 1.
Refer especially to the paragraph on Page 11 under Figure 3. After reading the
paragraph under Figure 3, connect the alarm relay leads as desired.
INSTALLING THE CONDUIT
Only UL listed, Type 4X, raintight conduit hubs and cable glands are to be used.
The hub is to be connected to the conduit of a rigid conduit system before the
hub is connected to the enclosure. Select, measure, cut, and install the conduit
in accordance with all National Electrical Code (NEC) requirements, all local and
applicable building and electrical codes, as well as the manufacturer’s
instructions. Ensure a sealed, watertight installation.
