• This device was designed to be permanently
secured and connected on a building or on a
suitable structure. The device must be permanently
secured and connected 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 surge voltage 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 windings,
or by fitting UL 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 and the
following rated operation conditions: Type 2 (SPDs
permanently connected to the power network and
intended for installation on the load side of the
service equipment); Nominal Discharge Current
(In) 20kA min. For example: FERRAZ SHAWMUT,
STT2240SPG-CN, STT2BL240SPG-CN rated
120Vac/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 power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• The separate protective earthing terminal provided
on this product shall be permanently connected
to earth.
• This is a Class A product. In a domestic
environment this product may cause radio
interference. In this case the user may be required
to take adequate measures.
• 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%).
• 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.
• The appliance includes moving parts. Make sure
that the unit is positioned where it is inaccessible
under normal operating conditions.
• Attach the Dangerous Moving Parts label near the
device. (Fig. 4, page 9).
• Do not use the appliance in the presence of
inflammable substances.
