Instrumentation
General
Designed to monitorize current of electrical charge of any system.
Usage and Working Principle
Make the connections according to the diagram. Make the connections of current transformers used for ampermeter before the electrical chargewhich required to measure in the system.
Current transformers don't sense the current of electrical charge which connected before them. Put max 5A charge for SDM-A36, SDM-A48, SDM-A72 and SDM-A96 types. Otherwise, device might be damaged or might give error.
Push "menu" button when the power is on. Set the current transformer ratio by "up"-"down" buttons and re-push "menu" to record your setting. You can see the current of system.Current transformers which used for direct ampermeters are in the same box with device and current ratio is already fixed, in this case, there is no menu for record.
Maintenance
Switch off the device and release from connections. Clean the trunk of device with a swab. Don't use any conductor or chemical might damage the device.
Make sure device works after cleaning.
Warnings
Please use the device according to the manual.
Don't use the device in wet.
Include a switch and circuit breaker in the assembly.
Put the switch and circuit breaker nearby the device, operator can
reach easily.
Mark the switch and circuit breaker as releasing connection for device.
