Instruction manual
| Types SDV-R and SDV-R-AR distribution circuit breakers
Hazardous voltages and high speed moving parts.
Can cause death, serious injury or property damage.
All replacement of circuit breaker components must be performed with
the circuit breaker completely de-energized and the springs discharged.
The definition of “usual service conditions” is
subject to a variety of interpretations.
Because of this, the user is best served by
adjusting maintenance and lubrication
intervals based on your experience with the
equipment in the actual service environment.
With the inclusion of an optional heater
monitoring circuit to provide a means of
ensuring the space heaters are functioning
properly, the maintenance interval can be
extended beyond what is shown in Table 3.
Regardless of the length of the maintenance
and lubrication interval, Siemens
recommends that circuit breakers should be
inspected and exercised annually.
For the safety of maintenance personnel as
well as others who might be exposed to
hazards associated with maintenance
activities, the safety-related work practices of
NFPA 70E (especially chapter 1) should
always be followed when working on
electrical equipment.
Maintenance personnel should be trained in
the safety practices, procedures and
requirements that pertain to their respective
job assignments.
This instruction manual should be reviewed
and retained in a location readily accessible
for reference during maintenance of this
equipment.
The user must establish a periodic
maintenance program to ensure trouble-free
and safe operation.
The frequency of inspection, periodic
cleaning and preventive maintenance
schedule will depend upon the operation
conditions. NFPA Publication 70B, “Electrical
Equipment Maintenance” may be used as a
guide to establish such a program.
Note:
A preventive maintenance program is
not intended to cover reconditioning or major
repair, but should be designed to reveal, if
possible, the need for such actions in time to
prevent malfunctions during operation.
