Safety 13
• Stop the motor.
• Ensure that there is no voltage on the drive power terminals according to step 1 or
2, or if possible, according to the both of the following steps:
1. Disconnect the motor from the drive with a safety switch or by other means.
Measure that there is no voltage present on the drive input (L1, L2, L3), motor
output (U, V, W), or brake terminals (R1, R2).
2. Ensure that the motor cannot rotate during work. Make sure that no other
system, like a hydraulic crawling drive, is able to rotate the motor directly or
through any mechanical connection like felt, nip, rope, etc. Measure that there
is no voltage present on the drive input (L1, L2, L3), output (U, V, W), or brake
/ regeneration terminals (R1, R2). Ground the drive output terminals
temporarily by connecting them together as well as to the PE.

General safety
WARNING! Ignoring the following instructions can cause physical injury or
death, or damage to the equipment.
• The drive is not field repairable. Never attempt to repair a malfunctioning drive;
contact your local ABB representative or Authorized Service Center for
replacement.
• When operating a rotary motor with no load coupled to its shaft, remove the shaft
key to prevent it flying out when the shaft rotates.
• Operating the MicroFlex e150 in torque mode with no load attached to the motor
can cause the motor to accelerate rapidly to excessive speed.
• Make sure that dust from drilling does not enter the drive during the installation.
Electrically conductive dust inside the drive can cause damage or lead to
malfunction.
• Drives must be installed inside an electrical cabinet that provides environmental
control and protection. Installation information for the drive is provided in this
manual. Motors and controlling devices that connect to the drive should have
specifications compatible with the drive. If not installed in an electrical cabinet,
barriers around the equipment are required.
• Avoid locating the drive immediately above or beside heat generating equipment,
directly below water or steam pipes, or in the vicinity of corrosive substances or
vapors, metal particles and dust.
• Ensure sufficient cooling. Failure to meet cooling air flow requirements will result
in reduced product lifetime and/or drive overtemperature trips.
• The metal heat sink on the left side of the MicroFlex e150 can become very hot
during normal operation.
