Power Requirements
The 5000 System components are shipped according to the customer order and are fused and set for
the voltage of the required mains power. The power requirements are stated near the power entry
for the component and in the Specification Section of this manual. Supplemental information may
appear in the Customer Drawing (CD) package.
The 5000 Field Unit is fused internally with a 1 amp fuse for nominal 230 Vac applications, and 2
amp for 100 and 115 Vac. The rupture speed is either a type M or T (slow blow). The voltage is set by
specific wiring in the unit. Information on the various wiring configurations is contained in the CD
package.
The 5000 Controller uses a "universal" DC switching power supply and will accommodate a volt-
age range of 85 to 265 Vac. The power supply has an on-board fuse which serves as the Controller's
power protection at any voltage in the range.
Other components of a extended or custom 5000 System will have power requirements, fusing or
breakering, and voltage information contained in the CD package.
These factory set configurations must not be altered by the operator. Only qualified service person-
!
nel may access these settings for modification or inspection. The power requirements labeling on
the exterior of a system component must be clearly re-marked to indicate any new AC source infor-
WARNING
mation. If qualified personnel are not available to perform these tasks, contact AMETEK service.
Physical wire types for power and interconnects should be of the agency approved type (UL/CSA/
Harmonized, etc.) for the region of installation. The CD package will contain suggestions for wire
gauges and/or information on current/power requirements in the case of power cable.
Explosion Hazard Warning
If the 5000 Controller is to be located in a Class I, Division 2 area, the power source must be shut
down for service or maintenance. Never disconnect power at the unit until the area is known to
!
be non-hazardous. Substitution of parts may impair suitability for Class I, Division 2 use. If a
specific procedure requires the unit to be energized, a hot work permit may be required; check with
WARNING
safety consultant.
Power, input and output wiring (I/O) must be in accordance with Class I, Division 2 wiring methods
[Article 501-4 (b) of the National Electrical Code, NFPA 70] and in accordance with the authority
having jurisdiction.
Installation Requirements
These components are meant too be permanently connected devices. Qualified installation person-
nel are to adhere to nationally recognized standards for power cable type and building breaker or
fusing for use with this type of equipment, having the power requirements stated in the CD pack-
age, and for use in the intended environment (general purpose or hazardous, see below). This
equipment is designed to operate from local branch circuits (Installation Category II). In addition to
