Mechanical installation
The following documents are required for
installation:
These operating instructions
Order specific drawings
Installation and commissioning report form
(see page 32).
A responsible person (or supervisor) must be
assigned to oversee the installation and
commissioning work. This person must
instruct personnel during installation and
commissioning tasks, and check for
compliance with the applicable safety
procedures.
The installation and commissioning work
must be performed by authorized personnel
who must be qualified persons as described
on page 2 of this instruction manual.
Suitable lifting apparatus in good working
condition and transport vehicles with
sufficient load-bearing capacity must be used
for installation.
All safety regulations, including NFPA 70E and
OSHA regulations, must be observed.
Installation and commissioning must be
documented (see “Installation and
commissioning report,“ page 32).
Torque requirements for all hardware are as
follows:
.38 inch: (31 lbf-ft ± 5 lbf-ft)
.50 inch: (75 lbf-ft ± 9 lbf-ft)
.62 inch: (120 lbf-ft ± 20 lbf-ft)
.75 inch: (250 lbf-ft ± 40 lbf-ft).
Preparatory work
Both the installation and commissioning
report (see page 32) and these installation
instructions are based on the sequence of the
work to be performed. The on-site conditions
may result in deviations from the sequence
shown.
The following preparatory work must be
performed:
Instruct installation and maintenance
personnel with regard to:
1. Safety
2. Cleanliness at installation site
3. Safety markings
4. Dealing with incidents or unexpected
conditions
Check delivery documents for
completeness
Check all shipping units for shipping
damage
Inspect power pole ground conductor and
install ground conductor, if necessary
If installation is on a substation frame,
check the foundation for the substation
frame and install ground connection, if
required.
Mounting the recloser on the pole
The recloser is mounted in several steps.
Refer to the frame installation drawing
provided with the order specific drawings for
information on mounting frames.
Lifting the recloser switch units
Figure 18: Lifting of the switch units shows
the proper technique for lifting the single-
phase switch unit and the triple-single
recloser with mounting frame. The lifting
cables should be attached to all four lifting
lugs and the lifting cables must not touch the
encapsulated pole units.
