General Safety; Printed Circuit Boards - ABB MicroFlex e190 User Manual

General safety

These instructions are intended for all who install and service the drive.
WARNING! Ignoring the following instructions can cause physical injury or
death, increased electromagnetic interference and equipment malfunction:
• Handle the unit carefully.
• Take care when lifting. When carrying, do not suspend the unit from the front
panel as it could detach and cause the unit to be dropped.
• Beware of hot surfaces. The metal heat sink on the left side of the MicroFlex e190
can become very hot during normal operation. The surfaces of drive system
components (such as a mains choke or braking resistor, if present) become hot
when the system is in use, and remain hot for a while after disconnection of the
electrical supply. A brake resistor can generate enough heat to ignite combustible
materials. To avoid fire hazard, keep all combustible materials and flammable
vapors away from brake resistors.
• Ensure that debris from drilling and grinding does not enter the drive when
installing. Electrically conductive debris inside the unit may cause damage or
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.
• Do not attach the drive by riveting or welding.
• The MicroFlex e190 must be installed where the pollution degree according to UL
and EN 61800-5-1 shall not exceed 2.

Printed circuit boards

WARNING! Ignoring the following instructions can cause damage to the
printed circuit boards and/or void the warranty:
• Wear a grounding wrist band when handling the boards. Do not touch the boards
unnecessarily. The printed circuit boards contain components sensitive to
electrostatic discharge.
