Controller and Programming Pendant
• The controller and the programming pendant are not explosion-proof ( the explosion-
proof programming pendant is available as an option). Never install the controller and the
programming pendant that are not explosion-proof in a hazardous location.
• Keep a minimum space of 60 cm around the controller for maintenance. When the suffi-
cient space is not available, provide equipment for maintenance such as a drawing-out
system.
• An exhaust fan is provided on the back of the controller. Keep enough space behind the
controller so that air can be exhausted properly.
• Do not install the controller and programming pendant close to any noise source such as
the power supply for other devices.
• Install the controller in a location where the optimum atmosphere, temperature, and
humidity are assured and provide protection against water drops or thinner. If necessary,
install a control room to supply clean and temperature-controlled air.
