MOUNTING OF DYNAMIC BRAKING UNIT

17

3.1.

Environmental Conditions

Do not mount the braking unit in direct sunlight. Isolate the

braking unit from excessive vibration.

Protect the braking unit from moisture, dust, metallic particles,

corrosive gasses and liquids. Install the braking unit on a non-
flammable surface and as smooth as possible.

In case of installing many braking units in a panel, consider the air

flow for power dissipation.
