10 Introduction to the manual

Hardware description
Contents of this chapter
The chapter describes the hardware of BAMU-12C auxiliary measurement unit.
Hardware description
BAMU-12C auxiliary measurement unit is a measurement unit for precise voltage and current
measurements. The unit has:
• two 3-phase voltage inputs
• three current inputs
• indication LEDs
• 24 V DC supply voltage
• optical link for communication with the overriding drive control unit.
Compatibility
The measuring unit is compatible with BCU-02, -12 and -22 control units. The control unit
must also be equipped with a control program that can communicate with the measuring
unit, for example the IGBT supply control program. For the compatibility with other control
programs, see their firmware manuals.

Installation
Contents of this chapter
The chapter instructs in installing BAMU-12C auxiliary measurement unit.
Checking the delivery
Check that there are no signs of damage. Check that the package contains:
• measurement unit
• this manual.
Placing
Install the module inside a cabinet/cubicle in indoor environment. Leave enough space for
cabling. Make sure that the temperature will not be not excessive.
Do not install the measurement unit in the immediate vicinity of electromagnetic disturbance
sources, such as relays, contactors, brake choppers, power and motor cabling. The minimum
recommended distance from such components is 200 mm (7.9 in). We recommend to install
metallic screening between the measurement unit and the source of disturbance. This can
reduce the required distance.
Mount the control unit so that air can pass freely through the ventilation holes in the housing.
Avoid mounting directly above heat-generating equipment.
WARNING!
Protect the unit against accidental contact. There are connectors that are connected
to drive main circuit potential.

WARNING!
No condensation is allowed. There are connectors that are connected to drive
main circuit potential.
Mechanical installation
1. Install a standard 35 × 7.5/15 mm DIN rail to the cabinet into which the unit is to be
installed.
2. Fasten the two latches to the back of the measurement unit with four screws.
3. Click the measurement unit to the rail as shown below.
4. Make sure that the installation rail is grounded properly, either via the assembly plate,
or with a separate grounding wire. The unit is grounded through the rail.
