Power Supply Wiring
CE for Starter or Drive
Important:
•
All Trane-supplied remote starters and
drives used in conjunction with CDHH
®
Trane
chillers will be CE-compliant per
European Union (EU) directives and
International Electrotechnical Commission
(IEC) standards to which the CDHH
chillers also comply. All Trane-supplied
remote starters and drives must be used
with CDHH Trane
compliance.
•
For remote starters and drives, basic
details are provided on remote starter/
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
the unit (maximum overcurrent protection).
•
Always refer to as-built schematic wiring
diagrams and the chiller Installation,
Operation, and Maintenance manual
located inside the chiller-mounted control
panel (regardless of unit- or remote-
mounted starter or drive) for details on
wiring, safety, installation, and warnings.
•
Refer to drive-specific Installation,
Operation, and Maintenance manuals for
drive and option installation specifics for
unit- and remote-mounted adaptive
frequency drives.
•
Customers are responsible for all field
wiring with respect to EMC and EMI
interference. Customers are responsible to
mitigate the risks associated with EMC
and EMI interference that can occur as a
result of customer-provided field wiring as
dictated by local, national, and
international codes. This also implies that
for remote-mounted starters and drives,
customers are responsible for the entire
field wiring into the starter/drive as well as
between the starter/drive and the chiller/
compressor terminals with respect to EMC
and EMI interference. It also implies that
customers are responsible for incoming
power wiring to both the starter/drive and
CPTR option enclosure unit-mounted
panel with respect to EMC and EMI
interference.
All customer wiring, including power wiring to starters/
drives/CPTR Option/UPS shore power, needs to be
separated: 24–27 Vdc, 110–120 Vac, and 380–600 Vac
each need to be in separate conduit runs.
For 110/120V customer wiring, including power supply to
CPTR option, it is required that the customer provides
60
®
chillers to ensure CE
some sort of surge protection and all customer wiring
needs to be run in conduit.
For remote starters interfacing with the Trane
wiring needs to be run in conduit. Any Ethernet cables
being used by customer to interface with the Trane
must be shielded Ethernet cabling.
The customer is required to provide an overcurrent
protective device upstream of all starters and drives in
accordance with IEC standards and/or any applicable local
and national codes.
Service personnel must use proper PPE for servicing and
should also use proper lockout/tagout procedures during
servicing: lock the starter disconnect handle before
servicing to prevent accidental pulling of disconnect handle
at the starter panel. In addition, service personnel should
first disconnect the main supply disconnecting device
upstream of the starter or drive before performing any
service on any part of the chiller.
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 first. Removal of
touch-safe covers is at the customer/service
personnel's own risk. After any service is completed,
if the touch-safe covers have been removed, they
need to be put back in to ensure safety and
protection.
