Me2 Series

Installation Manual

Chapter 1 - General Information 1.1- Introduction

The Motortronics ME2 Series is a high performance generalpurpose micro AC drive that incorporates a high efficiency Pulse Width Modulated (PWM) design and IPM technology.

The output closely approximates a sinusoidal current waveform to allow variable speed control of any conventional squirrel cage AC induction motor.

Installation Manual

Chapter 2 - Power and Control Wiring

2.1 - Power and Control Wiring

This chapter deals with recommended power wiring practices for the ME2 Series AC drive. Remember, you must always conform to the National Electrical Code (NEC) and any applicable local codes. Always make sure the keypad is off, the LEDs are off, and the DC bus is discharged before adding or changing any wiring.

Warning! This section involves working with potentially lethal voltage levels! Caution must be used to prevent personal harm. Do not service equipment with voltage applied! To avoid shock hazard, disconnect main power and wait until the LED on the main control board goes out before working on the control. Warning labels (not supplied) must be attached to terminals, enclosure and control panel.

• DO NOT touch any circuit components while AC power is on or immediately after the main AC power is disconnected from the unit. Wait until the LED on the control board goes out.

• DO NOT make any connections to the drive before the unit is disconnected from the AC power. Failure to adhere to this warning could result in serious or lethal injury.

• Only use in a pollution degree 2 macro-- environment or equivalent.

•Never connect the input power wiring to the drive terminals T1, T2, or T3.

•Always use UL/CSA approved wire and ring lugs.

•Always make a positive ground termination to the Earth terminal of the drive.

•Use copper conductors only and size field wiring based upon 75º wire only.

	ME2-1P5	12	20
						14 AWG
	ME2-2P2	4.5	10	14-12 AWG
					22-18 AWG

	ME2-201	12	20
	ME2-202	20	30			12 AWG
	ME2-203	30	40	12-10 AWG		10 AWG

Notes:

1.240 VAC units are suitable for use on a circuit capable of delivering not more than 5000 RMS symmetrical amperes, 240 Volts maximum.

2.Always ensure that values used conform to NEC and all applicable local codes.

Note: Keypad operator cannot be removed.
