Up to an ambient temperature of +40 °C, a set-up height of up to
1000 m and a pulse frequency of up to 4 kHz, the frequency
inverters of the M-Max
TM
series do not require any space at the
sides.
Higher ambient temperatures (up to a maximum of +50 °C), pulse
frequencies f
PWM
(up to maximum 16 kHz) and set-up heights (up
to 2000 m) require space on the sides of at least 20 mm.
Fixing
You can mount an M-Max
TM
frequency inverter on screw mounts
or on a mounting rail.
Fastening with screws
The number and arrangement of required bore holes (mounting
dimensions a1 and b1 in figure 20) are also imprinted in the base
plate of the M-Max
TM
device.
Install the screws in the specified positions first. Then set the
frequency inverter on the prepared wall-mount and tighten all
screws. The permitted maximum tightening torque for the
fastening screws is 1.3 Nm.
