AFDE-SVU02F-EN
Note:
Graphic labels (shown above) are used for CE
application only.
Important:
•
Before servicing, disconnect all power sources and
allow at least 10 minutes for capacitors to discharge.
•
All electrical enclosures-unit or remote-are IP2X.
CE for AFDE Drives
Important:
•
All Trane-supplied drives must be used with CVHH or
CDHH Trane chillers to ensure CE compliance.
•
Basic drive details are provided on drive nameplate.
Please refer to the chiller unit nameplate located on the
chiller-mounted control panel for details on wire sizing
(minimum current ampacity) and overcurrent
protection sizing upstream of unit (maximum
overcurrent protection).
•
Always refer to as-built schematic wiring diagram and
the chiller
Installation, Operation, and Maintenance
manual located inside the chiller-mounted control
panel for details on wiring, safety, installation, and
warnings.
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives or
other energy storing components provided by Trane or
others, refer to the appropriate manufacturer’s literature
for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. If this equipment is
interlocked with other equipment, 115 volts AC may be
present in the cabinet even though the main power is
disconnected. If this is the case, these interlock signals
should be deactivated before any work is performed on
this equipment. Suitable warning tags or disconnects
should be added to these circuits and all circuits should
be tested before attempting to energize or service the
controller.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
WARNING
Capacitors Must Be Allowed To
Discharge!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Each time power is removed, allow at least 10 minutes
for DC units to discharge after power is disconnected
before servicing. Use extreme caution when applying
power. Equipment terminals and other internal parts of
the controller are at line voltage when AC power is
connected to the controller. All ungrounded conductors
of the AC power line must be disconnected from the
controller before it is safe to touch any internal parts of
this equipment.
WARNING
Lockout/Tagout Before Removing Touch-
Safe Covers!
Failure to follow instructions regarding touch-safe
covers could result in death or serious injury. Touch-safe
covers inside panels are there for protection and may
be removed if necessary for service only and only after
disconnection of main power supply. Before removing
any touch-safe cover, ensure that there is no line power.
Removal of touch-safe covers would be at the
customer/service personnel’s own risk. After any
service is completed, if the touch-safe covers have been
removed, the touch-safe covers must be replaced to
ensure safety and protection.
