Red Lion C48C - Manual (Page 9)

INSTALLATION & CONNECTIONS
The C48 Counter meets NEMA 4X/IP65 requirements for indoor use
to provide a watertight seal in steel panels with a minimum thickness of
0.09 inch, or aluminum panels with a minimum thickness of 0.12 inch.
The units are intended to be installed into an enclosed panel. The
complete unit assembly (i.e. PC boards and bezel), MUST be in the case
when mounting the unit.
Multiple Unit Stacking
The C48C is designed for close spacing of multiple units. Units can be
stacked either horizontally or vertically. For vertical stacking, install the
panel latch with the screws to the sides of the unit. For horizontal
stacking, the panel latch screws should be at the top and bottom of the
unit. The minimum spacing from center line to center line of units is 1.96”
(49.8 mm). This spacing is the same for vertical or horizontal stacking.
Note: When stacking units, provide adequate panel ventilation to ensure
that the maximum operating temperature range is not exceeded.
