Field Control Wiring
DANGER
LOCKOUT/TAGOUT all power sources prior to wiring or servicing the unit.
Electrical shock hazard that may cause severe injury or death. Connect only
low voltage NEC Class II circuits to the terminal blocks. Reinstall and secure
all protective front panels when the wiring installation is complete.
Rebel Applied units are available with several control schemes
which may require low voltage eld wiring. Use the Unit
Specic Electrical Schematics to determine which control
connections will be required for installation. Check unit specic
electrical documentation in the door of the control panel. Figure
136 is a graphical representation of TB2 and Table 11 shows
the possible eld connections that can be made.
Figure 136: Graphical Representation of TB2
Rebel Applied units operate with 115V and 24V control circuit
power. All eld control wiring connections are made at the class
II terminal block TBLV2 which is located in the Low Voltage
Control Panel, shown in Figure 139.
NOTE: The installation of all eld wiring, must comply with all
applicable local codes and ordinances. The warranty
may be limited or certain aspects excluded if the eld
wiring is not in accordance with these standards.
If a single conduit containing 24V and 115V wiring is
run above the rooine between units, consider the
24V wiring within as an NEC Class I wiring system.

Field Output Signals
There are several output signals on the MicroTech Controller
that may be available for eld connections. For example, the
Alarm Output and the Auxiliary Output, shown in Figure 137,
can be used to send signals to external systems.
A eld supplied 24VAC relay must be installed in order to
interface these outputs with a system external to the unit.
When the respective signal is active, the signal terminal
will be energized with 24VAC. The coil of the eld supplied
24VAC relay must be wired between the signal terminal and
the common terminal. These would be terminals TBLV2-215
and TBLV2-217 in the case of the Alarm Output and terminals
TBLV2-216 and TBLV2-217 in the case of the Auxiliary Output.
The eld installed relay coil may draw no more than 3VA or
125mA at 24VAC.
