Power supply cord and plug protection -
Protect the power supply cord and plug from
foot traffic, being pinched by items placed upon or against them at electrical outlets, and
its exit from the unit. For units intended to operate with 230 VAC, 50 Hz, the power
supply cord must comply with the latest versions of
IEC 60227
. For units intended to
operate with 120 VAC, 60 Hz, the power supply cord must comply with the latest
versions of
UL 62
and
CSA 22.2 No.49
.
10.
Power disconnect -
Units have power supplied to the unit whenever the power cord is
inserted into the power source. The power cord plug is the main power disconnect
device for switching off the voltage for all units.
11.
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.
12.
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.
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)
