MULTIPLE UNIT STACKING
The T48 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.

ACCESSORY - EXTERNAL SSR POWER UNIT
The external SSR Power Unit is used with T48s equipped with Logic/SSR
Drive outputs to switch loads up to 240 VAC @ 45 Amps, 25°C ambient. The
unit is operated by applying a low level DC control signal to the isolated
input. The unit features zero cross detection circuits which reduces radiated
RFI when switching load currents. With no contacts to wear out, the SSR
Power Unit provides virtually limitless operational life. The unit is supplied
with an integral heat sink for immediate installation.
External SSR Power Unit:
