Carrier 17/19EX - Manual (Page 36)

Introduction
Prior to initial start-up of the 17/19EX unit, those involved in the start-up, operation, and
maintenance should be thoroughly familiar with these instructions and other necessary job data.
This book is outlined so that you may become familiar with the control system before performing
start-up procedures. Procedures in this manual are arranged in the sequence required for
proper machine start-up and operation.
This unit uses a microprocessor control system. Do not short or jumper between
terminations on circuit boards or modules; control or board failure may result.
Be aware of electrostatic discharge (static electricity) when handling or making
contact with circuit boards or module connections. Always touch a chassis
(grounded) part to dissipate body electrostatic charge before working inside con-
trol center.
Use extreme care when handling tools near boards and when connecting or dis-
connecting terminal plugs. Circuit boards can easily be damaged. Always hold
boards by the edges and avoid touching components and connections.
