All electrical interconnections are brought out to a convenient junction box for easy installation. The
junction box has a cover, which is easily unscrewed for access to the internal terminals. Two conduits are
provided: one for the AC power and the second for the output signals (see Figure 3 for details).
CAUTION: ALL ELECTRICAL WIRING SHOULD COMPLY WITH THE NEC AND
ANY LOCAL STANDARDS.
Figure 3: Junction Box Wiring
A switch or circuit breaker marked as the disconnecting device must be included in the building
installation. This device should be in close proximity to the equipment and within easy reach of the
operator.
A single-phase power source is required to operate the instrument. The standard instrument requires
100 to 240 volts AC. The hot, neutral, and ground leads should be connected to the appropriate line
power inputs using the insulated terminals provided with the instrument (p/n 11002-001). The junction
box contains a 2 Amp fuse for the AC power. Replacement parts for the fuses are available from Infrared
Industries, Inc. (p/n 11428-001). The outputs available from the junction box include the standard 4-20
mA isolated output and serial communication.
