ONTROL UNIT INSTALLATION

1.1 A

SSEMBLY DIRECTION

Assembly direction (top and bottom) is shown on dimension / assembly drawing of unit.

1.2 S

UPPORT FRAME

When you design the support frame for control units, take care of that those frames are
stabile and stiff enough to prevent extra vibrations and shocks.

1.3 W

ALL MOUNTING

Use units wall brackets for mounting the unit on the wall. Do NOT drill any assembly
holes through units back! In any cases all kind of drilling and similar work should be
avoided inside the unit. If you should use the internal assembly holes of the control
unit, do not drill through the control unit. Make the fastening holes to the bulkhead or
equal first and fasten after that. All units are designed for wall assembly.

1.4 C

OOLING

For cooling there should be some free space around the electronic units. Normally the
dimension drawings of the motor controllers have also reservation for cooling space
around the controller. All heat producing equipments (diesel motors, boilers, etc.)
should be at least 1 m away from units and not under the units. Their cooling air outlet
should not blow against control unit.

1.5 V

IBRATION ABSORBER

Vibration absorber should be used if electronic unit is mounted near to machinery or
place where noticeable vibration might occur. Make sure that the mounting base for
unit is steady enough.

1.6 C

LEANLINESS AND PURITY

Keep always the control unit doors closed when you do not work with it to avoid
impurities to go inside of the control unit. If somebody is working near of the causing
impurities or equal, prevent these impurities go inside of the control units. All filters of
units should be replaced about 3 months after the commissioning

Try to avoid any oil mist to getting inside units. Keep the doors closed and/or put some
protection around the units.

To keep the units clean the doors should be closed all the time when there is no work
to do with units. When assembly and connection works have done, all trash should
clean away from units. Use cleaning cloth, which is not getting fluffy.

1.7 C

ONDENSED WATER

To avoid condense keep the doors closed during assembly work. Also the temperature
should be steady and warm enough (>15 C). After assembly work when the control
voltage can be connected it is good to keep the voltage on all the time if the condition is
bad. Then the components stay at operating temperature and dry.
