Notes: 1) BAH to mount the motor disconnect switch near the fan access door.
2) BAH to wire the motor ground wire to a ground bar option in the disconnect switch.(on supply fan and reactivation fan
motor disconnect switches).
3) Provide orange or red '460 Volt' label on the motor disconnect cover.
4) All wiring from various unit mounted electrical components are wired to one (1) 'finger safe' terminal bank located in
one (1) NEMA 3R unit mounted junction box. The junction box shall contain the following:
a) One side of terminal bank shall be reserved for field wiring.
b) Label the terminal bank as 'TB 3'.
c) All signal wires (4-20 mA) are run separate from power wires.
d) All electrical component ground wires shall be attached to one common bus bar located inside the junction box.
5) BAH to use wire ferrules on all termination points.
6) Use aluminum flex conduit for connection to rotating equipment.
7) High voltage and 120V wiring shall be run separate from low voltage (<60 VAC or DC) wires or cable.
8) All wire ends at termination and splits must be numbered according to electrical diagram.
9) All conduit to run as close to the top of the unit as possible and be secured to the AHU wall or roof. No conduit
is allowed on or near the floor of the unit. Conduit not to run across any plug panels or access openings. Conduit to
be routed in a manner that the coil removable panels will not be hindered or that the conduit comes in contact with
the coil connections.
10) Use twisted shielded pair for all signal wires. Sheathing is plenum grade (FA).
11) All control components and control loops must be tested at the main terminal bank. Do not test at the individual
device. Attach all internal checkouts pertaining to control tests. Passing initial must be clearly shown. Provide copy
