NOTES:
1. EconoMi$er2 actuator and controller are shipped with the EconoMi$er2 — not with power exhaust.
2. Connections from End Switch Plug to the EconoMi$er2 controller are made by installer.
3. If a single power source is to be used, size wire to include power exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit. Determine the new MCA including the power exhaust using the fol-
lowing formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 48HJD006---5 unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust.
MCA New = 28.9 amps + 1.6 amps = 30.5 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.
