Mounting
guidelines
Select a cabinet position that meets these guidelines:
Flat, solid surface capable of supporting the approximate
9.75 pound (4.423 kilogram) weight of the unit.
Free of excessive vibration or shock.
Minimum unobstructed space of two inches (50 mm) at the
fan input on the unit bottom and the exhaust on the unit top.
Operating temperature of:
5445 - 0 to 50 degrees C at full rated current
5345 - 0 to 60 degrees C at full rated current
0 to 60 degrees C with idle current reduction enabled
(microstep mode).
Mounting
procedure
Bolt the unit to the cabinet using the three slots (refer to the
dimensions figure) using a 1/4 - 20 or #10 (M6 metric equivalent)
bolt.
Power
dissipation for
cabinet
The 5345/5445 dissipates power causing cabinet heating. Power
dissipation is determined by a number of factors, such as output
current, motor winding impedance, input step rates, and idle
current reduction. The 5345 is factory preset for 2.5 amps/phase
current and idle current reduction enabled. The 5445 is factory
preset for 5 amps/phase current and idle current reduction enabled.
For an estimate of the power dissipation for use in calculating
cabinet cooling requirements, use the values shown:
