This chapter is for use by qualified personnel and authorized service personnel only.
Perform Automatic Disconnection Test
The automatic disconnection test can be run at any convenient power level.
To perform the automatic disconnect test:
1. With the Xantrex GT500 running, open the external disconnect switch (if
load-break rated) on the AC output circuit, or in some other manner de-
energize the AC grid.
2. Check the front panel display to verify that the inverter ceases to energize its
output terminals. After a convenient period, re-close the disconnect.
3. Verify that the inverter display indicates that the inverter does not re-start until
after the required reconnect time delay. The default value is five minutes
minimum.
Revise Protection Settings (If Required)
If default protection settings will be changed as authorized by the utility, follow
the
WRITE menu procedure documented in the Operation and Maintenance
Manual (Document Part Number 975-0602-01-01).
Activating the Xantrex RS485/Modbus Communications Kit
(Optional)
The Xantrex RS485/Modbus Communications Kit allows remote users to control
and monitor the status of the Xantrex GT500 (see Figure 4-1 on page 4–14). If
you want to activate the Xantrex RS485/Modbus Communications Kit, follow the
instructions below.
To activate the Xantrex RS485/Modbus Communications Kit protocol in the
Xantrex GT500:
1. Press the
MENU key on the Xantrex GT500’s front panel.
2. Type in the password
594, and then press ENTER.
3. Using the arrow keys, scroll to the
Modbus ON option, and then press ENTER.
4. Type
1, and then press ENTER.
Once
Modbus ON is set to 1, the Xantrex GT500 will communicate via the
Modbus protocol as opposed to the Xantrex protocol.
The Xantrex GT500’s default Modbus address is factory set to 200. If more than
one Xantrex GT500 is connected to the same Modbus master device, each
Xantrex GT500 must have a unique Modbus address.
