INSTALLATION & OPERATION INSTRUCTIONS
PMDF PAD-MOUNTED SWITCHGEAR
NOVEMBER 2017 VER. 2.1
PAGE 3
Introduction
PMDF pad-mounted switchgear is designed to provide depend-
able on-the-line service and to make installation, operation
and maintenance as simple as possible. Federal Pacific PMDF
models meet applicable industry standards, which are ANSI 386
and IEEE C57.12.28.
High quality materials and careful workmanship have been com-
bined to provide the best switchgear available. The switchgear has
been thoroughly inspected and adjusted at the factory. However,
successful operation depends on proper installation and care.
This manual has been written to assist you in obtaining long and
economical service from your switchgear.
Read this manual before installing and operating your switchgear .
Receiving
Upon receipt of the switchgear, check each item received for
shipping damage. Each item should be checked against the ship-
ping manifest to assure that the proper number of items were
received. Should any shortage or damage exist, note it on the
shipping papers. A claim should be filed at once with the carrier
and the Federal Pacific agent or sales office should be notified.
The carrier is responsible for all damage occurring during tran-
sit. Receiving personnel must note all damage to equipment on
shipping papers so that claims can be processed.
Handling
Removable lifting plates are provided to allow the use of hooks to
lift the complete enclosure. The lifting device should be arranged
to evenly distribute the lifting force between the lifting plates.
Do not lift at an angle less than 60° from the horizontal. See
Figure 2. A spreader bar may be required to maintain the proper
minimum angles. Failure to comply with this requirement may
result in damage to the equipment.
The switchgear is securely mounted to a sturdy shipping pallet
with provisions for forklift use. The use of a forklift truck is not
recommended, but if this method is used the forks must extend
completely through the skid to avoid damaging the equipment.
Storage
The switchgear as received may be wrapped in a protective
plastic film, which must be removed for storage.
To avoid damage to the enclosure finish, the protective film
must be removed for outdoor storage of unit.
Export or special packing is available as an option based on
customer’s requirements and special conditions. Separate in-
structions are available for these situations.

General Description
PMDF dead-front pad-mounted
switchgear consists of one or more
single-pole 200 ampere bushing
wells to accommodate 200 ampere
loadbreak (or non-loadbreak) in-
serts and elbows. Alternately, the
unit may be optionally equipped
with 600 ampere bushings to ac-
commodate 600 ampere elbow
connectors. When used with 200
ampere bushing wells and load-
break inserts and elbows, and
other protective devices, the PMDF
switchgear provides a secure and
efficient means of single-pole
switching with elbows on the in-
coming lines.
In addition, the unit may be furnished with metering transformers
(voltage transformers and current transformers), or provisions
only for metering transformers, and with optional meter socket
(mounted on the enclosure or in a low-voltage compartment)
and associated wiring. When the unit is provided with “Mount-
ing Provisions only for Metering Transformers, the customer is
responsible for providing, installing, wiring, and connecting all
metering transformer and associated secondary components.
Security Features
PMDF pad-mounted switchgear meets the security require-
ments in IEEE C57.12.28 and incorporates a number of security
features to minimize hazards to operating personnel.
1. Rugged 11-gauge steel, using all welded construction of the
enclosure, with a bolted roof, and hinged and bolted doors
assures a tamper-resistant design.
2. Padlockable doors with security bolts provide customer-
controlled access.
3. 200 ampere bushing wells of cycloaliphatic epoxy and with
removable studs.

NOTICE
4. Hazard-alert signs and labels, both external and internal,
indicate potential hazards to personnel.
5. Full-width fiberglass barriers (or optional clear polycarbonate
barriers) behind doors on fuse compartment.
6. Wind brace to secure enclosure door open and a cable-
connected clip to secure inner barriers open.
WARNING
Before energizing the switchgear, remove all yellow and red
shipping caps on bushings and bushing wells, and replace
them with a suitable system of insulated separable connectors
(elbows), insulating protective covers, or plugs, as appropriate.
Failure to replace the shipping caps may result in flashover,
equipment damage, serious personal injury, or death.
