575 V transformer No. HT01AH859 is ordered separately from power exhaust

Economizer actuator and controller are shipped with the Economizer -
2
not with power exhaust.
Connections from End Switch plug to Economizer controller are

made by installer.
If a single power source is to be used, size wire to include
4
power exhaust MCA and MOCP.
For R-410A units, refer to the unit nameplate for MCA and
MOCP for installed power exhaust.
For R-22 units use the following calculations
Check MCA and MOCP when power exhaust is powered
through the unit. Determine the new MCA including the power
exhaust using the following formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using an electric cooling, 6-ton R-22 unit with
MCA = 28.9 and MOCP = 35, with CRPWREXJ030A01 power exhaust.
MCA New = 28.9 amps + 1.5 amps = 30.4 amps
If the new MCA does not go over the MOCP published, then MOCP would
not change. The MOCP in this example is 35 amps, the MCA New is below
35, therefore the MOCP is OK. If "MCA NEW" is larger than the published
MOCP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.
