▪
Make electrical connections with plugs removed from sockets, then place plugs into their sockets.
▪
Be sure that adequate cooling is provided.
▪
Be sure that the temperature of the environment will not exceed the maximum operating
temperature in any case.
Below conditions may damage the device:
▪
Incorrect connections.
▪
Incorrect power supply voltage.
▪
Voltage at measuring terminals beyond the specified range.
▪
Voltage at digital inputs beyond the specified range.
▪
Current through measuring terminals beyond the specified range.
▪
Overload or short circuit at relay outputs.
▪
Connecting or disconnecting data terminals while the device is powered on.
▪
High voltage applied to communication ports.
▪
Ground potential differences at non-isolated communication ports.
▪
Excessive vibration, direct installation on vibrating parts.
Below conditions may cause abnormal operation:
▪
Power supply voltage below minimum acceptable level.
▪
Power supply frequency out of specified limits.
▪
Incorrect phase order of voltage inputs.
▪
Current transformers not matching relevant phases.
▪
Incorrect current transformer polarity.
Current transformers must be used for current
measurement.
No direct connection allowed.
