Two variants of Group Marker Holders are available for
identification of Terminal Block assemblies:
GMH1, GMH2, GMH3, GMH4, GMH5 and GMH8 are to be mounted in the
grooves of End Clamps. CA509/G1 marking tag can be used with these
marker holders or can be directly mounted on the end clamp.
GMH6 & GMH7 can be mounted directly on Din Rails. A sticker
/ paper needs to be inserted in the slot which is covered by a
transparent plastic sheet..
