Electrical Connection
WARNING
Incorrect installation, wiring or power supply may cause overheating and
therefore personal injuries or damage to property.
For correct cabling of the device, always observe the presented wiring diagram
for the product version used.
The manufacturer cannot be held responsible for personal injuries or damage to
property as a result of incorrect handling, installation, wiring, power supply
and maintenance of the device.
Hardware
The bus termination shall be realized with 120 Ω resistor using the switch on
the electronics board.
NOTICE
Improper handling of the device may result in its damage.
- The power supply must be strong enough to ensure supply voltage within the specified range (see technical data) at any time and at all devices in the bus. This is particularly relevant when using long and thin cables as those can cause high voltage drop. Please note that a single EE660 requires peak current of 150 mA.

Address Setting
Address Switch
Address setting via PCS10 Product Configuration Software
All DIP switches at position 0 → address has to be set via PCS10.
Modbus (slave device): factory setting 65 (permitted values: 1…247).
BACnet (master device): factory setting 65 (permitted values: 0…127).
Example: Address is set via configuration software = factory setting.
Address setting via DIP switch
Modbus (slave device): Setting the DIP switches to any other address than
0, overrules the Modbus address set via PCS10 (permitted values: 1…247).
BACnet (master device): Setting the DIP switches to any other address
than 0, overrules the BACnet address set via configuration software.
BACnet Note: permitted values are 0…127. The 8th bit of the DIP switches
is ignored.
(ID 127 = 0111 111). To set address 0 via DIP switches, the 8th bit shall be
set to 1
(ID 0 = 1000 0000). Example: Address set to 11 (= 0000 1011 binary).\
BACnet Setup
Please refer to PICS (Product Implementation Conformance Statement),
available on www.epluse.com/ee660.

- The choice of measurement units (metric or non-metric) must be done according to the ordering guide, refer to EE660 datasheet.
- Switching from metric to non-metric or vice versa by using the PCS10 is not possible.
- Register number (decimal) starts from 1. 3) Register address (hexadecimal) starts from 0.
- Examples: For scale 100, the reading of 2550 means a value of 25.5. For scale 50, the reading of 2550 means a value of 51.
