the units. The M3575R must ALWAYS be mounted with the rear surface of the unit
to the mounting surface. Refer to Figure 3-1A for acceptable mounting orientation.
NEVER mount a unit in a horizontal position with its side parallel to the mounting
surface or floor as shown in Figure 3-1C. Do not mount the unit in an upside-down
position or on the underside of a mounting surface as shown in Figure 3-1B.
Mounting dimensions and provisions vary by unit chassis size and style. Refer to
Tables 6-1 thru 6-4 in Section 6.1 of this manual to determine the chassis size and
style for the unit. Then refer to Section 6.5 of this manual to determine the correct
mounting dimensions and provisions for the unit.

WARNING!
Only qualified electricians should perform and maintain the interconnection
wiring of this product. All wiring should be done in accordance with
National Electrical Code or equivalent regulations.
WARNING!
Never connect the Resistive Braking Load Module directly across the DC
bus! This would exceed the maximum duty cycle rating of the load. The
extreme overheating generated by the load resistors under this condition
could present a fire hazard in and around the Resistive Load Module.

 Please note that although the connection diagrams shown in Figures 3-3
and 3-4 depict a typical interconnection of the M3575R Resistor Module
with the M3575T Braking Transistor Module, the M3575R can be used
with any properly sized braking transistor module. Refer to the installation
manual for the transistor module used to determine proper connection
details.
 Be sure that the Resistive Load being connected meets the minimum load
resistance requirements listed in the Braking Kit and/or AC Drive
documentation.
 Field connection terminals used on the Bookshelf (B*) and Mini (M*)
chassis units are depicted in Figure 3-3.

Wire types and sizes should be chosen in accordance with national and/or
local electrical codes as well as module termination limitations outlined in
Table 3-1 to meet the voltage and RMS current ratings of the M3575R
module as listed Section 6.1 of this manual.
Figure 3-4 shows typical connections for a single M3575R module.
