Electric Heat Typical Wiring Diagram - 3-Speed EC Motor
Figure 103: Motor Control Box, (460 Volt, 60 Hz, 3 Phase)
Notes:
1. All electrical installation must be in accordance with
national and local electrical codes and job wiring schematic.
2. Automatic temperature control supplier is responsible to
ensure controls operate correctly and protect the unit.
3. Numbers along top of schematic designate the location of the
contact by line number.
4. SW2 contacts 5, 6 and 7, 8
open only when SW2 is in OFF position.
5. T6 only on units with chilled water.
6. Typ 6 elm. on 750 & 1000 cfm units only, terminal block
furnished when total heating amps is less than 48 amps.
6 elm. on 1250 & 1500 cfm is on a different schematic.
8. OH2 supplied on ceiling units, connect wire 515 to OH1 on AV (floor) units.
9. Automatic temperature control can be wired to TB-DE for DE cooling operation.
Typical operation is to wire from the TB-DE to a normally open relay, with the
relay closing on control call for cooling.
For additonal information, contact Daikin Applied applications.
10. Motors are factory programmed for specified air flow.
Contact Daikin Applied for replacement.
Refer to unit wiring diagram located behind the bottom
access panel at the right end, for actual wiring. Improper
wiring can cause equipment and property damage.
CAUTION
!
Use copper conductors only. Unit terminals are not
designed to accept other types of conductors. Failure to
do so may cause damage to the equipment.
CAUTION
!
Disconnect all electrical power before
servicing unit to prevent injury or death
due to electrical shock.
