Notice!
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 isolating 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) 20 kA min.
For example: FERRAZ SHAWMUT, STT2240SPG-CN, STT2BL240SPG-CN rated 120/240 VAC,
(In=20 kA)

Ventilation - Any openings in the unit enclosure are provided for ventilation to prevent
overheating and ensure reliable operation. Do not block or cover these openings. Do not
place the unit in an enclosure unless proper ventilation is provided, or the manufacturer's
instructions have been adhered to.
Object and liquid entry - Never push objects of any kind into this unit through openings
as they may touch dangerous voltage points or short-out parts that could result in a fire
or electrical shock. Never spill liquid of any kind on the unit. Do not place objects filled
with liquids, such as vases or cups, on the unit.
Controls adjustment - Adjust only those controls specified in the operating instructions.
Improper adjustment of other controls may cause damage to the unit. Use of controls or
adjustments, or performance of procedures other than those specified, may result in
hazardous radiation exposure.
Overloading - Do not overload outlets and extension cords. This can cause fire or
electrical shock.
Power sources - Operate the unit only from the type of power source indicated on the
label. Before proceeding, be sure to disconnect the power from the cable to be installed
into the unit.
–
For battery powered units, refer to the operating instructions.
–
For external power supplied units, use only the recommended or approved power
supplies.
–
For limited power source units, this power source must comply with EN60950.
Substitutions may damage the unit or cause fire or shock.
–
For 24 VAC units, voltage applied to the unit's power input should not exceed ±10%,
or 28 VAC. User-supplied wiring must comply with local electrical codes (Class 2
power levels). Do not ground the supply at the terminals or at the unit's power
supply terminals.
–
If unsure of the type of power supply to use, contact your dealer or local power
company.
Servicing - Do not attempt to service this unit yourself. Opening or removing covers may
expose you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
