DANGER
Electrical shock hazard. Can cause severe injury or death.
Connect only low voltage NEC Class II circuits to terminal
blocks TB2 and TB5. Reinstall and secure all protective
deadfront panels when the wiring installation is complete.
Roof Pak applied rooftop units are available with several
control arrangements which may require low voltage eld
wiring. Detailed descriptions of various eld control wiring
options and requirements are included in the “Field Wiring”
section of IM 919, MicroTech III Applied Rooftop Unit
Controller. Refer to the unit wiring diagrams for additional
installation information.
Wiring must comply with applicable codes and ordinances.
The warranty is voided if wiring is not in accordance with these
specications.
RPS, RDT, and RFS Units
All eld control wiring connections are made at the class II
terminal block TB2, which is located in the main control panel.
Field wiring connections to the 115 volt receptacle and lights
are made at terminal block TB7, which is also located in the
main control panel. Refer to Figure 51, Figure 52, and Control
Panel on page 8. Two 7/8ʺ knockouts are provided for wire
entry.
RFS/RCS Units
The RCS unit receives 115V and 24V control circuit power
and a number of control signals from the RFS unit. Two 7/8ʺ
knockouts are provided in the right side of the RCS control box.
Interconnecting wiring enters the RFS unit through 7/8ʺ
knockouts in the bottom of the main control panel. The
interconnecting wiring is connected to TB4 in the RFS unit and
TB5 in the RCS unit. Refer to Figure 52. A 7/8ʺ knockout is also
available in the end of the unit base as shown in Figure 50.
NOTE: If a single conduit containing 24V and 115V wiring
is run above the rooine between the RFS and RCS
unit, install the 24V wiring as an NEC Class I wiring
system.
