Clearances
Minimum clearances as outlined in the PEC Clearances section of this document must be followed .
Mounting
The PEC must be mounted to a rigid platform or structure with all four (4) of the PEC mounting studs secured and prop-
erly torqued (see Eaton Installation Guide for torque specifications). The 4 nuts that are installed between the factory
provided frame bracket and the PEC housing must be retained on the PEC studs when relocating the PEC as they are
integral to the PEC assembly .
Airflow Requirements
The PEC unit is air cooled and requires unrestricted air flow to the air inlet duct on the front of the PEC and the air exhaust
duct on the rear of the PEC . The temperature of the air entering the PEC must be the same temperature as the ambient
air temperature, thus ducting or otherwise providing intake air that has been heated above ambient temperature is not
permitted .
Service Access
Adequate access must be maintained to allow for service of the air cleaner and easy access to the service switch on the
front side of the PEC, as well as removal of the PEC unit for service
Warning: The PEC is not to be used or installed in a manner susceptible to being used as a step or seat .
HAZARDOUS VOLTAGE: To reduce the risk of possible serious injury
(Shock, Burn or Death): Components marked with High Voltage should be
avoided. Service must be performed by qualified personnel only.
