Installation Instructions for cFMus:
WARNING – Do not remove or replace while circuit is live when a flammable or combustible
atmosphere is present.
WARNING – Substitution of components may impair suitability of the equipment.
CAUTION – To prevent injury, read the manual before use. Warning – If the equipment is
installed within an ultimate enclosure, the inner service temperature of the enclosure
corresponds to the ambient temperature of the module.
WARNING – If a device is operated in an ambient temperature of more than 45 °C, the
temperature of the device housing may be higher than 70 °C. The device must therefore be
installed so that it is only accessible to service personnel or users that are aware of the
reason for restricted access and the required safety measures at an ambient temperature
higher than 45 °C.
WARNING – The equipment is intended to be installed within an enclosure/control cabinet.
The inner service temperature of the enclosure/control cabinet corresponds to the ambient
temperature of the module. Use cables with a maximum permitted operating temperature of
at least 20 °C higher than the maximum ambient temperature.
