The auxiliary voltage control transformer, X5, is protected by three fuses, which are located
in this section. F21 and F22 are located on the primary of the auxiliary control voltage
transformer, and F4 is located on the secondary of the transformer. These fuses are CC time
delay 600 V rated.
The EMC filter is typically used on agency projects requiring CE certification. FLTR1 is a
two-stage zero sequence filter rated at 7A, and when used, is applied between the
disconnect switch (DS1 in the Control Section) and the EC Blowers’ motor starter.

Cooling System Control
The cooling system consists of several parts including either an EC or AC blower described
in the next section. In addition to those components, each blower has three 600V Class J
time delay fuses or a 600 V three phase 10 Amp circuit breaker that feeds a 2.5% line
