ty provision carefully before attempting to adjust or service the
unit. 2
RECEIVING AND HANDLING
Upon delivery of the equipment, inspect the shipping containers and contents for indications of
damages incurred in transit. If any of the items specified in the bill of lading are damaged, or the
quantity is incorrect, do not accept them until the freight or express agent makes an appropriate
notation on your freight bill or express receipt.
Claims for loss or damage in shipment must not be deducted from your invoice, nor should
payment be withheld pending adjustment of any such claims.
Store the equipment in a clean, dry area. It is advisable to leave the equipment in its shipping
container until ready for use. Each amplifier is checked carefully before shipment. However,
upon receipt, the user should make sure that the amplifier received corresponds to or is properly
rated in terms of rated voltage and current for the type of motor which is to be driven. The
descriptive label affixed to the amplifier specifies electrical ratings.

Technical specifications for SMTBM Module
The SMTBM Module is designed for the SMTBSI or SMTBD Brushless amplifier fitted with the
optional shunt regulator ("dp") mounted in the amplifier. The module incorporates a DC bus
power supply capable of driving a motor with an output of 20 Arms continuous and 60 Arms
peak maximum (5% duty cycle).
A three phase isolation transformer or an auto-transformer is required to power the unit. Direct
connection to the main 220 VAC line is possible (10Arms or less) when using the appropriate line
filter.
The shunt resistor needs to be mounted outside the unit in an area protected against any physical
contact and if possible near a cooling fan.
The single-axis rack housing MUST BE GROUNDED in order to ensure physical protection in
case of insulation failures to the mains. INFRANOR will withdraw any warranty on all material
which does not meet this requirement.

The shunt resistor is delivered with the amplifier and must be connected to the 2 point connection
mounted on the side of the amplifier (option "dp"). The resistor is mounted inside a protective
housing to avoid electrical shocks (see chapter 4.3.0 for dimensions).

Solution 1: It is mandatory when using an auto-transformer to use the 220VAC for the auxiliary
supply at the output of the auto-transformer.
Do not use direct 220VAC from the line.
Solution 2: It is also possible to use a small isolation transformer to power the auxiliary supply.
Caution:
The use of an auto-transformer means that there is no isolation between the main line
and the amplifier (and consequently to the motor). It is then MANDANTORY to
mount fuses or thermal circuit breaker (MOL) in case of a short-circuit.
It is also recommended to use the "AMP READY" logic signal from the amplifier to
open the power relay when a default occurs.
