5. Installation
Qualified personnel with appropriate training and experience must perform the installation of the VSN700. Follow standard safety
precautions during all procedures. Appropriate personal protection equipment (PPE), such as safety gloves and safety glasses is
recommended.
WARNING –
B
During normal operation, dangerous voltages flow through many parts of the system, including: terminals, all I/O
Modules (Inputs and Outputs) and their circuits. All Primary and Secondary circuits can, at times, produce lethal voltages and
currents. Avoid contact with any current-carrying surfaces. Installation may also require close proximity to high-voltage high-current
wires, so proper caution should be exercised when installing these devices.
WARNING –
B
Make sure all power is switched off before performing installation. These servicing instructions are for use by
qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that specified in the operating
instructions unless you are qualified to do so.
5.1 Preparation
Make sure you have the following tools and materials prior to starting installation.
5.1.1 Tools
• Standard Electrician’s Toolkit
• Personal Protective Equipment (Gloves, Goggles, Clothing)
5.1.2 Materials and Test Equipment
• Twisted-Pair RS-485 Wire (Belden#3106A or equivalent).
NOTE –
D
DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA WIRE.
• Ethernet Cable to make Network Connection
• Laptop Computer with Internet Browser
• Second Ethernet Cable for Logger configuration
• Mounting Screws and/or Brackets
It is also useful to know if you need to perform Asset Registration or final End-to-End Data Checks after physical installation is complete.
If so, you will need a
User ID / password
to log in to Aurora Vision
Plant Portfolio Manager
, and additionally you will need Administrator
privileges to access the
Administration
tool in Aurora Vision. See the “Commissioning” section for details.
5.2 VSN700 installation
1. Check packaging for all components
• Data Logger
• Power Supply Adapter (not included with VSN700-05-00 model)
• DIN rail mounting kit for 35mm DIN rails (VSN700-05-00 model only)
2. Determine the indoor location of the VSN700.
For reliable operation, it is required that the data logger be located within 100m (330 ft.) of an Ethernet connection and within 1200m
(4000 ft.) of the inverter(s).
3. Mount the data logger.
The logger comes with flanges with pre-drilled holes for easy mounting. A DIN rail mounting kit comes with the VSN700-05-00 model
and can be optionally ordered with other models. All data logger versions require a weather protected site. The included power supply
requires an ambient temperature between 0oC and 40oC but the logger can operate between -40oC and 85oC.
4. Connect shielded twisted-pair wire to the RS-485 terminals on the inverter(s). If there are multiple inverters, wire the inverters in a daisy
chain configuration. Refer to your inverter manual for information on terminal locations and daisy chaining inverters. Use RS-485 data
wire with one twisted pair, one ground conductor, and a shield with drain wire (Belden#3106A or equivalent).
NOTE –
D
DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA WIRE.
5. For systems with multiple inverters, the RS-485 network must be terminated at the final inverter by a switch near the RS-485 terminal
block. The farthest inverter in the daisy chain must be terminated by setting the inverter termination switch to ON. For all other inverters
in the daisy chain, turn OFF the termination switch. Below are pictures of RS-485 terminals in various inverters, as well as locations of
the termination switch.
NOTE –
D
In some environments you may experience poor RS-485 signal quality due to noise. If signal quality is a problem, double-
check that the last inverter in the chain is terminated and other inverters are not terminated. If problems persist, it may prove helpful
to attach a 120 Ohm 0.5 Watt resistor across screw terminals 1 and 2 on the data logger.
READ THE MANUAL –
E
If you need more information, consult your inverter’s manual for locating the RS-485 terminals and the
termination resistor switch.
