Auxiliary Supply
Two-way fixed connector with 2·5mm
2
(12AWG) stranded wire
capacity. 110 to 400V a.c. 50/60Hz ±10% or 120V to 350V d.c.
±20%. Consumption < 10W.
Pulse Relay Output
The pulse relay output can be set to generate pulses to represent
imported kWh, exported kWh, imported kVArh or exported kVArh.
Rate
can be set to generate 1 pulse per:
0·001 = 1 Wh/VArh
0·01
= 10 Wh/VArh
0.1
= 100 Wh/VArh
1
= 1 kWh/kVArh
10
= 10 kWh/kVArh
100
= 100 kWh/kVArh
1k
= 1 MWh/MVArh
10k
= 10 MWh/MVArh
The rate cannot be set to a value that could result in more
than 2 pulses per second.
Pulse width
200/100/60 ms.
Relay Rating
240V ac 50mA
RS485 Output for Modbus or JC N2 Protocol
For Modbus protocol, the following RS485 communication
parameters can be configured from the Set-up menu:
Baud rate
2400, 4800, 9600, 19200, 38400
Parity
none/odd/even
Stop bits
1 or 2
RS485 network address
nnn
– 3-digit number, 1 to 247
Modbus Word order
Shows the word order (Hi/Lo) of the 8-bit
bytes in the Modbus message format. This setting can only be
changed from the Modbus port.
Note that with odd or even parity, Stop Bits are forced to one.
For JC N2 protocol, only the RS485 network address can be
configured. The range of addresses is 1 to 255.
