Introduction - Carrier 09FC020 Installation, Start-Up And Maintenance Instructions

Only trained, qualified installers and service mechanics should in-
stall, start up, and service this equipment.
Untrained personnel can perform basic maintenance functions,
such as cleaning coils. All other operations should be performed
by trained service personnel.
When working on the equipment, observe precautions in the liter-
ature, and on tags, stickers, and labels attached to the equipment
and any other safety precautions that may apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling, rigging, and setting bulky
equipment.
Separate power sources (main and control power circuits) are
used for these units. Be sure both main and control power
circuits are disconnected before servicing. Failure to do so
could result in personal injury from electric shock.
WARNING
Open all remote disconnects before servicing this equipment.
Failure to do so could result in personal injury from electric
shock.
WARNING
The free cooling module is not to be used by children or
persons with reduced physical, sensory, or mental capabilities.
Anyone with lack of experience and knowledge shall have
supervision or have been given instruction.
Electrical shock can cause personal injury and death. After unit
power is disconnected, wait at least 20 minutes for the Variable
Frequency Drives (VFD) capacitors to discharge before
opening drive.
DANGER
DANGER
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
control center.
Use extreme care when handling tools near boards and when
connecting or disconnecting terminal plugs. Circuit boards can
easily be damaged. Always hold boards by the edges and avoid
touching components and connections.
This equipment uses, and can radiate, radio frequency energy.
If not installed and used in accordance with the instruction
manual, it may cause interference to radio communications. It
has been tested and found to comply with the limits for a Class
A computing device pursuant to International Standard in
North America EN 61000-2/3 which are designed to provide
reasonable protection against such interference when operated
in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever
measures may be required to correct the interference.
Always store and transport replacement or defective boards in
anti-static shipping bag.
