AFS670 | PRECAUTIONS AND SAFETY
DANGER 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.
DANGER 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.
WARNING Non-observance can lead to death or injury.
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.
WARNING Non-observance can lead to death or injury.
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.
WARNING Non-observance can lead to death or injury.
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.
