Tofino Xenon Security Appliance Tofino SA
Release 04 05/2015
National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Grounding the device
Grounding the device is by means of a separate ground connection on the
device.
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
The overall shield of a connected shielded twisted pair cable is connected
to the ground connector on the front panel as a conductor.
Supply voltage
The supply voltage is electrically isolated from the housing.
Connect only a supply voltage that corresponds to the type plate of
your device.
Every
time you connect the electrical conductors, make sure that the
following requirements are met:
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device
(e.g., a switch or a plug). This disconnecting device is clearly iden-
tified. So in the case of an emergency, it is clear which discon-
necting device belongs to which power supply cable.
The electrical wires are voltage-free.
The power supply is Class 2 compliant.
The supply voltage inputs are designed for operation with safety
extra-low voltage. Connect only SELV circuits with voltage restric-
tions in line with IEC/EN 60950-1 to the supply voltage connec-
tions.
Supply with AC voltage:
A fuse is located in the outer conductor of the power supply.
The neutral conductor is on ground potential. Otherwise, a fuse is
also located in the neutral conductor.
Regarding the properties of this fuse:
See “General technical data”
on page 42.
Supply with DC voltage:
A fuse suitable for DC voltage is located in the plus conductor of the
power supply.
The minus conductor is on ground potential. Otherwise, a fuse is
also located in the minus conductor.
Regarding the properties of this fuse:
See “General technical data”
on page 42.
The wire diameter of the power supply cable is at least 1 mm²
(North America: AWG16) on the supply voltage input.
