Non-observance can lead to death or injury.
Power up the equipment only when the installation procedure is finished and
verified:
→ The equipment is mounted correctly.
→ The cables are plugged and secured.
Non-observance can lead to death or injury.
Equipment might be connected to high voltages and can cause an electric
shock when incorrectly installed.
→ If possible respecting the operational requirements, switch off the power
supply before manipulating anything at the equipment. Use the manual
switch on the circuit breaker, and/or fully disconnect/unplug the power
cables from the equipment.
→ If it is not possible to switch off the power supply always assume a hazard-
ous voltage to be present.
Equipment might be connected to high voltages and can cause an electric
shock during periods of lightning.
→ Do not work on the equipment during periods of lightning.
→ Do not connect or disconnect cables during periods of lightning.
Enclosures containing rechargeable batteries or having direct connection to
the main cable ducts can be subject to a build-up of an explosive concentra-
tion of gas or vapors in extreme conditions.
→ All compartments and equipment containing rechargeable batteries must
have appropriate ventilation provided to prevent the build-up of an explo-
sive concentration of any gas released by the batteries. Ventilation must
be to the external atmosphere and not into other parts of the enclosure.
→ Cable entry and exit points from enclosed ducts must be sealed to prevent
entry of explosive gas and vapors into the enclosure.
→ All potential sources of ignition must be extinguished and procedures
relating to gas detection observed before undertaking any work.
Omitting the fuses or circuit breakers in the power supply circuits might lead
to seriously damaged equipment or create a fire in the case of overload or
short circuits.
→ Connect the equipment only to a switchable power supply and switch off
the power supply before installation or de-installation of any equipment.
→ Install fuses or circuit breakers in the power supply circuits outside of the
equipment. Recommended fuses:
AFS670 V2.0 for low voltage (24VDC-48VDC, Y order code): 6.3A;
AFS670 V2.0 for high voltage (110VDC-250VDC; 110VAC-240VAC, 50-60Hz, Z
order code): 2.5A.
→ Make sure that the fuses or circuit breakers are correctly installed and
intact for each of the power supply circuits.
