with the instructions of user manual.
DANGER!
The device must not be put into service if the operator is not sure that all connections are correctly accomplished.
2.2 MOUNTING
MMW03-CH is placed vertically into the gap located in the panel. After the product is placed into the panel, fixing
brackets should be installed on the product. After that it should be fixed to the panel wall with the screws.
DANGER!
Before wiring up voltage and current ends to MMW03-CH, you must be sure that the power is cut.
DANGER!
The product is connected to current transformer(s). Before disconnecting current transformer leads, be sure that they are
short circuited elsewhere or connected to a parallel load which has sufficiently low impedance. Otherwise dangerously high
voltages will be induced at the current transformer leads. Same phenomena also apply for putting into service.
