Installation – Electrical
General Recommendations
When reviewing this manual keep in mind:
• All field-installed wiring must be in accordance with
local regulations and CE directives and guidelines.
Be sure to satisfy proper equipment grounding
requirements according CE
• The following standardized values - Maximum Amps -
Short Circuit Amps - Starting Amps are displayed on
unit nameplate.
• All field-installed wiring must be checked for proper
terminations, and for possible shorts or grounds.
Note:
always refer to wiring diagrams shipped with
chiller or unit submittal for specific electrical schematic
and connection information.
WARNING Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
CAUTION!
Time before to work on the electrical panel
of the unit with Low Ambient option: once the unit is
off (confirmed by the extinction of the display), it is
mandatory to wait five minutes before working on the
electrical panel.
CAUTION! To avoid corrosion, overheating or general
damage, at terminal connections, unit is designed for
copper conductors only. In case of aluminum conductors
an intermediate connection box must be added. In case
of aluminum cable bi material connecting device is
mandatory. Cable routing inside control panel should
be made case by case by installer.
Important!
Do not allow conduit to interfere with other components,
structural members or equipment. Control voltage
(230 V) wiring in conduit must be separate from conduit
carrying low voltage (<30V) wiring. To prevent control
malfunctions, do not run low voltage wiring (<30V) in
conduit with conductors carrying more than 30 volts.
Soft starter recommended settings
Acceleration time: 0.5 second speed Start-up torque: 50%
Deceleration time: 0 second
CAUTION!
Inverters are equipped with integrated filters.
They are not compatible with insulated neutral load
earthing arrangements.
WARNING! High voltage!
Any contact with electric components , even after the
unit has been switched off, can cause serious injury or
death. Wait at least 4 minutes after switching off the unit,
until the current dissipates.
Grounding
Note the fan speed inverter has a high leakage current.
Be sure to ground the unit and take this into account
when installing the differiential protection device.
Differential protection should be suited for industrial
machinery with current leak which can be higher than
100 mA (several motors and frequency drives).
Installer-Supplied Components
Customer wiring interface connections are shown in
the electrical schematics and connection diagrams that
are shipped with the unit. The installer must provide the
following components if not ordered ith the unit:
• Power supply wiring (in conduit) for all field-wired
connections.
• All control (interconnecting) wiring (in conduit) for
field supplied devices.
• Circuit breakers.
Power Supply Wiring
WARNING Ground Wire!
All field-installed wiring must be completed by qualified
personnel. All field-installed wiring must comply with
local codes and regulations. Failure to follow this
instruction could result in death or serious injury.
All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
local codes and regulations.
WARNING Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
All wiring must comply with local codes and regulations.
The installing (or electrical) contractor must provide
and install the system interconnecting wiring, as well
as the power supply wiring. It must be properly sized
and equipped with the appropriate fused disconnect
switches. The type and installation location(s) of the
fused disconnects must comply with all applicable
codes. Knock-outs for wiring are located on the bottom
right side of the control panel. The wiring is passed
through these conduits and connected to the disconnect
switch. To provide proper phasing of 3-phase input, make
connections as shown in field wiring diagrams and as
stated on the WARNING label in the starter panel. For
additional information on proper phasing, refer to “Unit
Voltage Phasing.” Proper equipment ground must be
provided to each ground connection in the panel (one
for each customer supplied conductor per phase). High
voltage field-provided connections are made through
knockouts on the right side of the panel.
