The instrument must not be powered and used until its definitive assembly is on the cabinet's door. Whether the instrument is not used as manufacturer's specifications, the protection of the instrument can be damaged. When any protection failure is suspected to exist (for example, it presents external visible damages),the instrument must be immediately powered off. In this case contact a qualified service representative. 3.1.- Installation Mounting Instrument is to be mounted on 35mm Din-rail. Keep all connections inside the cabinet. Note that with the instrument powered on, the terminals could be dangerous to touch and cover opening actions or elements removal may allow accessing dangerous parts. Therefore, the instrument must not be used until this is completely installed. Notes: Auxiliary power: MCM400 meter with AUX power input, if not for a special statement, we provide the 85265VAC/DC power interface for standard products.
