• This device was designed to be permanently
installed on a building or on a suitable structure.
The device must be installed permanently before
any operation.
• Installation category (also called Overvoltage
Category) specifies the level of mains voltage
surges that the equipment will be subjected to.
The category depends upon the location of the
equipment, and on any external surge protection
provided. Equipment in an industrial environment,
directly connected to major feeders/short branch
circuits, is subjected to Installation Category III. If
this is the case, a reduction to Installation Category
II is required. This can be achieved by use of an
insulating transformer with an earthed screen
between primary and secondary, or by fitting
listed Surge Protective Devices (SPDs) from live
to neutral and from neutral to earth. Listed SPDs
shall be designed for repeated limiting of transient
voltage surges, suitable rated for operating voltage
and designated as follows: Type 2 (Permanently
connected SPDs intended for installation on the
load side of the service equipment overcurrent
device); Nominal Discharge Current (In) 20kA min.
For example: FERRAZ SHAWMUT, STT2240SPG-CN,
STT2BL240SPG-CN rated 120/240Vac, (In=20kA).
Maximum distance between installation and
reduction is 5m.
• Use a Class 2 listed UL tranformer, compliant with
the Standards in force, only for products marked
UL, powered at 24Vac.
• A disconnecting device, readily and easily
accessible, must be incorporated in the electrical
system of the building for rapid intervention.
• The separate protective earthing terminal provided
on this product shall be permanently connected
to earth.
• For continued protection against risk of fire,
replace only with same type and rating of fuse.
Fuses must be replaced only by service personnel.
• The installation is type TNV-1, do not connect it to
SELV circuits.
• In order to reduce the risk of fire, only use UL Listed
or CSA certified telecommunication line cord sizes
greater than or equal to 26AWG.
• Hazardous moving parts. Keep fingers and other
body parts away.
• Connect the device to a power source
corresponding to the indications given on the
marking label. Before proceeding with installation
make sure that the power line is properly isolated.
The supply voltage should never exceed the limit
(+/-10%).
• The electrical system to which the unit is
connected must be equipped with a 20A max
automatic bipolar circuit breaker. The minimum
distance between the contacts must be 3mm
(0.1in). The circuit breaker must be provided
with protection against the fault current towards
the ground (differential) and the overcurrent
(magnetothermal).
• If it is necessary to transport the device, this should
be done with great care. Abrupt stops, bumps and
violent impact could damage the unit or injure the
user.
• To comply with the main supply voltage dips and
short interruption requirements, use a suitable
Uninterruptable Power Supply (UPS) to power the
unit.
