J BEFORE USE
An insulation sheet has been inserted to maintain the quality of
the Totalizer in the event of a long period without use. Be sure to
remove this sheet before attempting to use the product.
Remove the insulation sheet and press the Reset Key on the
front panel of the Counter. (With the H7ET-N,-NV(-H),-NV1(-H),
models, “0” or “0.0” will be displayed after 1 s.)
Switch settings on the Counter must be performed before
mounting it to a control panel.
Do not use the Counter in locations subject to:
SSevere changes in temperature.
SCondensation as the result of high temperatures.
J MOUNTING PRECAUTIONS FOR
Although the operating section is watertight (conforming to
NEMA 4, IP66), a rubber gasket is provided to avoid water
leakage through the gap between the Counter and panel cutout.
Unless this rubber gasket is tightly squeezed on, water may
permeate inside the panel. For this reason, be sure to tighten the
screws for fixing the panel-mounting bracket.
