INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate the aging process of
the bezel.
INSTALLATION
PBLPT installation information is contained in the LDD Bulletin. Refer to
that bulletin for instructions on installing the module.
The unit meets NEMA 4/IP65 requirements for indoor use, when properly
installed. The Apollo Indicators are intended to be mounted into an enclosed
panel with a gasket to provide a water-tight seal. Two mounting clips and
screws are provided for easy installation. Consideration should be given to the
thickness of the panel. A panel which is too thin may distort and not provide a
water-tight seal. (Recommended minimum panel thickness is 1/8".)
After the panel cut-out has been completed and deburred, carefully slide the
panel gasket over the rear of the unit to the back of the bezel. Insert the unit into
the panel. As depicted in the drawing, install the screws into the narrow end of
the mounting clips.
Thread the screws into the clips until the pointed end just protrudes through
the other side. Install each of the mounting clips by inserting the wide lip of the
clips into the wide end of the hole,
located on either side of the case. Then
snap the clip onto the case.
Tighten the screws evenly to apply
uniform compression, thus providing a
water-tight seal.
CAUTION: Only minimum pressure is
required to seal panel. Do NOT
overtighten screws.
