General precautions on indoor installation location
The EKCB unit is to be wall mounted in an indoor location that meets
the following requirements:
■
The space around the unit is adequate for servicing. Refer to
"7.3. Service space" on page 10.
■
The space around the unit allows for sufficient air circulation.
■
The installation surface is a flat and vertical non-combustible
wall, capable of supporting the operation weight of the unit (refer
to the "Technical specifications" on page 47).
■
During normal operation the control box may produce sound
which could be observed as noise. The sound origin can be
contactor activation. Therefore it is advisable to install the
control box on a firm wall and not in nor close to a sound
sensitive environment (e.g. bedroom).
■
Do not install the unit in places with high humidity (e.g.
bathroom).
■
The equipment is not intended for use in a potentially explosive
atmosphere.
■
Do not install the unit in places often used as work place.
In case of construction works (e.g. grinding works) where a lot of
dust is created, the unit must be covered.
■
Do not place any objects or equipment on top of the unit.
