Power Supply Wiring
Model RTSF chillers are designed according to European
standard EN 60204-1; therefore, all power supply wiring
must be sized and selected accordingly by the project
engineer.
Water Pump Power Supply
Provide power supply wiring with fused disconnect for
both the chilled water and condenser water pumps.
Electrical Panel Power Supply
Power supply wiring instructions for the starter/control
panel are:
Run the line voltage wiring in conduit to the access
opening(s) on the starter/control panel. See the product
catalog for wire sizing and selection information
and refer to general data that show typical electrical
connection sizes and locations. Always refer to submittal
information for your actual unit specifications.
Some connections required the user to provide an
external source of power. The 110V control power
transformer is not sized for additional load.
CAUTION
Unit with AFD version must not be linked to the neutral
wiring of the installation.
Units are compatible with the following neutral
operating conditions:
TNS IT TNC TT
Standard Special Special Special
- on request - on request - on request
Differential protection should be suited for industrial
machinery with current leak which can be higher than
500 mA (several motors and frequency drives).
CAUTION! To avoid corrosion, overheating or general
damage, at terminal connections, unit is designed for
copper Conductors only. In case of aluminum cable,
bi-material connecting devices are mandatory. Cable
routing inside control panel should be made case by
case by installer.
Compressor Motor Phase
Sequencing
Always verify that proper rotation of the chiller
compressor is established before the machine is started.
Proper motor rotation requires confirmation of the
electrical phase sequence of the power supply. The
motor is internally connected for clockwise rotation with
the incoming power supply phased A, B, C (L1, L2, L3).
To confirm the correct phase sequence (ABC), use a
phase meter.
Basically, voltages generated in each phase of a
polyphase alternator or circuit are called phase voltages.
In a 3-phase circuit, 3 sine wave voltages are generated,
differing in phase by 120 electrical degrees. The order
in which the 3 voltages of a 3-phase system succeed
one another is called phase sequence or phase rotation.
This is determined by the direction of rotation of the
alternator. When rotation is clockwise, phase sequence is
usually called “ABC.”
This direction may be reversed outside the alternator
by interchanging any two of the line wires. It is this
possible interchange of wiring that makes a phase
sequence indicator necessary if the operator is to quickly
determine the phase rotation of the motor.
Module and Control Panel
Connectors
All connectors can be unplugged or the wires can be
removed. If an entire plug is removed, make sure the
plug and the associated jack are marked for proper
location identification during reinstallation.
All electrical drawings, schematics and control panel
layout are included in the documentation package sent
with the chiller.
