2-8 Preparations
4. Tighten the upper and lower adapter mounting screws alternately with
only one turn of the screwdriver at a time to maintain an even torque
balance. Tighten the screw until the ratchet mechanism operates.
5. To allow heat to escape, do not block the area around the
Bulletin 900-TC8 Temperature Controller. (Ensure that enough space is
left for the heat to escape.) Do not block the ventilation holes on the
casing.
6. Allow as much space as possible between the Bulletin 900-TC8 and
devices that generate powerful high-frequency noise (e.g.,
high-frequency welders, high-frequency sewing machines) or surges.
7. Install the controller so that it is horizontal (can read the display
properly).
Note: When group mounting two or more Bulletin 900-TC8s, make sure that
the surrounding temperature does not exceed the allowable operating
temperature given in the specifications.
