General Safety
CAUTION: It is essential that all instructions in this manual be followed to
ensure proper operation of the equipment and safety of operating person-
nel. Use of equipment not specified herein, may impair protection provid-
ed by equipment. The use of this symbol is used throughout manual to
highlight important safety issues. Please pay particular attention to these
items.
Electrical Shock Caution
Certain MK-2 models are powered with HIGH VOLTAGE. No operator
serviceable parts are inside. All servicing is to be performed by qualified
personnel. Each MK-2 is provided with a "protective conductor terminal"
which shall be terminated to earth ground potential (See Electrical
Installation). This product's design complies with EN61010-1 installation
category II and pollution degree 2.
hazardous Location Caution
Certain MK-2 models can be used in Hazardous Locations (See
Specifications). These models shall only be used in applications covered
by stated ratings or those considered non-hazardous. Failure to comply
could result in damage to personnel and property. The following must be
maintained to assume safe operation:
1)
Enclosure integrity - The dimensions of the housing, cover or probe
shall not be altered.
2)
Electrical integrity - Substitution of electrical components may impair
intrinsic safety and therefore is prohibited.
3)
Maintenance - Power to all circuits must be disconnected before con-
ducting any investigation or maintenance.
Electromagnetic Compatibility (EMC)
The MK-2 was tested and found to comply with the standards listed below.
The MK-2 should not be used in residential or commercial environments.
Compliance to EMC standards was demonstrated by means of a test
setup using the following installation methods.
1)
MK-2 enclosure was connected to earth ground (protective earth).
2)
No specific wiring convention was used to supply power or
to retrieve output signal from the MK-2.
