- Page 3 AC power sources with our optional AC Module. All EPC controllers are designed to operate in harsh industrial environments. Installation is residential environments will require that the high voltage terminals of the unit to be shielded with a UL-Listed terminal protector or cover.
- Page 4 In those cases, the processor will have to be replaced as outlined in the next few sections. All EPC controllers use a standard 6-pin wiring harness. This makes it easy to swap or upgrade the controller, without the need to re-wire the controller.

Page 5: Installation Instructions
INSTALLATION INSTRUCTIONS A typical installation is shown below. If using an AC power source, a DC converter module must be placed where the battery is located. Controller can be installed in any orientation. A fan may be placed at or near the heatsink for additional cooling, in situations where the controller is operating at maximum or near maximum capacity most of the time. -
Page 6: Special Notice
The meter should read close to zero volts in all cases. If there is a high voltage leak anywhere in the system, it must be repaired immediately. All EPC controllers are fully isolated, and cannot leak voltage into the 12-volt system. - Page 7 LOW POWER TERMINAL CONNECTION All low power connections are pre-wired into a 6-pin wiring harness (see Figure 1) for easy installation. All EPC controllers use the same harness connector, and are interchangeable. Pin #1 (White Wire) Connect to the NEGATIVE (-) of your 12 VOLT power supply or battery.

(pin #6). To do this, you must first open the potentiometer’s enclosure to gain access to the terminals and solder a wire to the unused potentiometer terminal. All EPC brand potentiometers are 3-wire, and come with a 6-pin EPC harness pre- installed. Due to their accuracy and high quality construction, we strongly recommend using only EPC potentiometer units with this controller. - Page 9 INTERNAL HARNESS CONNECTION NOTE: Wiring harness colors may change inside of the controller, however the pin order is always the same. Replacement wiring harnesses assemblies are available directly from EPC.

The motherboard is available as a complete replacement assembly from EPC Corporation. The NEV Controller, EP-Junior, and most EP-1000 controllers only contain ONE driver module. The EP-2000, and special versions of the EP-1000 (such as the high frequency version) use TWO driver modules. -

Page 15: Controller Protection
Please note that a standard AC fuse should NOT be used in a DC circuit. The fuse must be SPECIFICALLY labeled for DC applications. For most larger motor applications, a 600A fuse will be sufficient. Application-specific fuses can be ordered directly from EPC. Also note that standard 125-volt and 240-volt DC circuit breakers (such as the AirPax JLM-1-1RLS5-30140-200) will NOT function correctly because of the high voltage present when the motor‘s windings are discharged during normal operation. -
Page 16: Wet Locations
WET LOCATIONS Although all EPC controllers are water resistant, care should be taken during installation to protect any exposed high voltage terminals. The standard NEMA enclosure used for all EPC controllers protects the internal components, and is completely sealed from the environment. - Page 17 HEATSINK DATA (EP-1000) Material: Extruded Aluminum Width: 10.000" Length: 12.000” Fin Height: 1.000" Base: .300" C/W/3": approximately 0.90 Weight per Inch: 0.48 lbs...
