Installation
Wiring
All classroom unit ventilators have 115V
motor power. Motor data can be found
in
Tables 9 and 10:
Control Power
CAUTION
Control Power Wiring
Wiring diagrams given in this manual
are typical. Actual wiring for particular
units may differ. To prevent damage to
the unit, refer to the diagram provided
on the unit for specific wiring informa-
tion.
Unit ventilator controls and control
wiring can be factory mounted or field
installed.
Wiring diagrams (
Figures 38 and 41
)
illustrate the standard unit motors with
one and two speed control. Terminal
wiring is provided by Trane and the
actual components used for a particular
installation may differ. Control and line
diagrams for the exact control system
used are provided with each unit.
CAUTION:
When installing field provid-
ed controls, do not alter or remove any
built-in unit safeties. Tampering with
unit safeties may cause unit overheat-
ing and possible fire hazard.
CAUTION:
Do not remove or alter the
wiring of the Time Delay Relay (DL).
Doing so may result in premature
motor failures.
Supply Power
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to
accept other types of conductors.
Failure to use copper conductors may
result in equipment damage.
Power supply wiring is to be connected
to terminals 1 and 2 at the junction box
in the left end pocket, below the dis-
charge air grille.
Electric Heat
Supply Power
Supply power wiring is to be connected
to the following line terminals in the
right hand end pocket:
1. 208V or 240V, 3-phase, 3 wire system:
L1, L2 and L3. (See
Figure 42
)
2. 480V, 3-phase, 4 wire system:
L1, L2, L3 and N (neutral)
See
Figure 43.
3. See Figure 44 for a typical unit line
and interconnecting wiring diagram
for Electric Heat Coils.
NOTE:
480 V/3-Wire is NOT compat-
ible with Trane Classroom Unit
Ventilator equipment. There must be
a 4-Wire system with a separate
ground.
NOTE:
The supply neutral wire must
be connected to the neutral terminal
block.
Operational controls and electric heat-
ing safety devices are factory mounted.
These devices are: high temp cut outs
and panel interlock, both of which de-
energizer electric heating elements
through the K1 safety contactor.
