MULTIPLE UNIT STACKING
The controller 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.
Caution: Disconnect power to the unit and to the output
control circuits to eliminate the potential shock hazard
when removing the bezel assembly.
UNIT REMOVAL PROCEDURE
To remove a unit from the panel, first loosen the panel latch screws. Insert
flat blade screwdrivers between the latch and the case on either side of the
unit, so that the latches disengage from the grooves in the case. Push the unit
through the panel from the rear.
REMOVING BEZEL ASSEMBLY
The bezel assembly, shown in Figure 3, must be removed from the case to
replace the output board. To remove the bezel assembly, insert a flat blade
screwdriver into the pry slot on either side of the unit. Twist the screwdriver
handle until the unit is ejected enough to allow removal.
Caution: The bezel assembly contains electronic circuits that can be damaged by
static electricity. Before removing the assembly, discharge static charge on
your body by touching an earth ground point. It is also important that the bezel
assembly be handled only by the bezel itself. Additionally, if it is necessary to
handle a circuit board, be certain that hands are free from dirt, oil, etc., to avoid
circuit contamination that may lead to malfunction. If it becomes necessary to
ship the unit for repairs, place the unit in its case before shipping.
INSTALLING BEZEL ASSEMBLY
To install the bezel assembly, insert the assembly into the case until the
bezel is fully seated against the lip of the case. Properly installing the bezel
assembly is necessary for watertight sealing.
