the freight carrier and file a claim within 15 days of receipt).

After unpacking, please check the following:

• Verify that the label specifications match your application
requirement.

• Check all electrical connections and screws. Verify that
there is no visible damage to any of the components.

Warning! Do not service equipment with voltage applied!
Unit can be a source of fatal electrical shock! T o 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.

Chapter 1 - General Information

1.1- Introduction

The Motortronics ME2 Series is a high performance general-
purpose 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.

Me2 Series 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! T o 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.

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.
