Watlow Series SD Limit - Manual (Page 8)

ç
Caution: Follow the installa-
tion procedure exactly to
guarantee a proper IP65/NE-
MA 4X seal. Make sure the
gasket between the panel
and the rim of the case is
not twisted and is seated
properly. Failure to do so
could result in damage to
equipment.

Installing and mounting
requires access to the
back of the panel.
Installing the 1/32 DIN Series SD Limit
1. Make the panel cutout using the mounting template dimensions in this chap-
ter.
2. Check that the rubber gasket lies in its slot at the back of the bezel. Insert the
limit into the panel cutout.
3. While pressing the bezel firmly against the panel, slide the mounting bracket
over the back of the limit.
4. If the installation does not require an IP65/NEMA 4X seal, slide the bracket
up to the back of the panel enough to eliminate the spacing between the gas-
ket and the panel.
For an IP65/NEMA 4X seal, use your thumb to lock the tabs into place while
pressing the limit from side to side. Don’t be afraid to apply enough pressure
to properly install the limit. If you can move it back and forth in the cutout,
you do not have a proper seal. The tabs on each side of the bracket have teeth
that latch into the ridges.
Each tooth is staggered at a different depth (from the front) so only one of the
tabs on each side is ever locked into the ridges at any time. Either the two
middle tabs or the two tabs diagonal from each other will be engaged.
5. If the matching tabs are not engaged, you do not have an IP65/NEMA 4X seal.
The space between the bezel and panel must be 0 to 0.48 mm (0 to 0.019 in)
maximum.
Removing the 1/32 DIN Series SD Limit
1. Remove the terminal cover and all of the wiring connectors from the back of
the limit.
2. Slide a thin, wide tool (putty knife) under all three mounting tabs, top then
bottom, while pushing forward on the back of the case. Be ready to support
the limit as it slides out of the panel cutout.
