PROJECT PLANNING INFORMATION
WARNING: Endangerment of electrical safety during installation and
maintenance work when the power supply is not switched off
An electrical accident can occur during installation and maintenance work
when the power supply to the device and/or lines is not switched off using a
disconnector switch/circuit breaker.
▸ Before starting the work, ensure the power supply can be switched off
using a power isolating switch/circuit breaker in accordance with
DINEN61010.
▸ Make sure the disconnector switch is easily accessible.
▸ An additional disconnecting device is mandatory when the power isolating
switch is difficult to access or cannot be accessed when connecting the
equipment after installation.
▸ The power supply may only be activated again after the work or for test
purposes by personnel carrying out the work under consideration of valid
safety regulations.
WARNING: Endangerment of electrical safety through power cable with
incorrect rating
When a removable power cable is used, electrical accidents can occur when
the specifications are not fully observed.
▸ Always observe the exact specifications in the Operating Instructions
(Technical Data Section) when replacing a removable power cable.
CAUTION: Device damage through incorrect or missing grounding.
During installation and maintenance work, it must be ensured that the
protective grounding to the devices and/or lines involved is effective in
accordance with EN 61010-1.
NOTICE: Responsibility for the safety of a system
The safety of the system in which the equipment is integrated is the
responsibility of the person setting up the system.
WARNING: Risk of fire due to hot gas escaping in installations with
overpressure conditions
On installations with overpressure, the purge air hose can be severely
damaged by escaping hot gas and can catch fire depending on the
temperature.
On plants with overpressure as well as gas temperatures over 200°C:
▸ Ensure reverse flow is prevented by fitting a (trip) flap or a valve.
▸ Regularly check the functionality of the reverse flow safeguard.
