6.4 Auxiliary Supply
This product is self-powered from any of the three phases.
6.5 Interfaces for External Monitoring
Three interfaces are provided:
• Pulse output 1 indicating real-time measured energy (configurable)
• Pulse output 2 3200IMP/kWh (not configurable)
The Modbus configuration (baud rate etc.) and the pulse relay output
assignments (kW/kVArh) are configured through the set-up screens.
6.5.1 Pulse Output
Opto-coupler with potential free SPST-NO Contact
(Contact rating 5-27V DC / Max current input: Imin 2mA and Imax 27mA DC).
The pulse output can be set to generate pulses to represent kWh or kVArh.
Rate
can be set to generate 1 pulse per:
0.001 = 1 Wh/VArh
0.01 = 10 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh
1000 = 1000 kWh/kVArh
Pulse width
200/100/60 mS.
6.5.2 RS485 Output for Modbus RTU
For Modbus RTU, the following RS485 communication parameters can be
configured from the set-up menu:
Baud rate:
2400, 4800, 9600, 19200, 38400
Parity:
none (default) / odd / even
Stop bits:
1 or 2
RS485 Network Address:
3 digit number - 001-247
Modbus™ Word order
Hi/Lo byte order is set automatically to normal as
defined in IEEE 754. It cannot be configured from the set-up menu.

7 Installation and Maintenance
7.1 Installation notes
Units should be installed in a dry position, where the ambient temperature is
reasonably stable and will not be outside the range -25 to +55
⁰
C.
Vibration should be kept to a minimum.
Preferably, mount the Integra so that the display contrast is not reduced by direct
sunlight or other high intensity lighting.
7.2 Input Wiring and Fusing
Voltage lines must be fused with a fast blow AC fuse 1A maximum. Auxiliary
supply lines must be fused with a slow blow fuse rated 1A maximum. Choose
fuses of a type and with a breaking capacity appropriate to the supply and in
accordance with local regulations.
A switch or circuit breaker allowing isolation of supplies to the unit must be
provided.
7.3 Wire Size
Voltage and current terminal blocks will accept 0.5mm² to 2.5mm² stranded
cable.
7.4 Maintenance
The front of the case should be wiped with a dry cloth only, using minimal
pressure. If necessary wipe the rear case with a dry cloth.
No user serviceable parts.
