Total Counters "H7EC-N"

H7EC-N

Dimensions with Y92F-34 Flush Mounting Bracket

Note: A Compact Flush Mounting Bracket (Y92F-35) can also be used. Refer to Accessories for details.

Panel Cutout

Waterproofing is not possible for dense mounting

• When mounting, insert the Counter into the cutout, insert the adapter from the back and push in the Counter while making the gap between the front panel and the cutout panel as small as possible. Use screws to secure the Counter. If waterproofing is desired, insert the waterproof packing.

• When several Counters are installed, ensure that the ambient temperature will not exceed specifications.

• The appropriate thickness of the panel is 1 to 5 mm.
