5. ELECTRICAL INSTALLATION
This Chapter describes the following:
1. The Need and selection of Potential Transformers (PTs) and Current Transformers (CTs)
2. Auxiliary Supply, PT and CT Connections
NOTE: For best wiring results with the new Terminal cover, please ensure the
following specs:
Improper wire-manship will damage the Terminals and require Factory Replacement.
This does not indicate defective manufacture and is not covered by product
warranties.
• Power Driver preferred, Hand Screw-Driver OK.
• TIP: Phillips preferred, DO NOT USE POZIDRIV TIPS. Flat OK
Screw Head Dia = 3.5mm, TIP Shaft Dia < 5mm.
IMPORTANT - Driver Shafts inserted angularly or of Dia 5mm or more WILL GET STUCK
in the Safety Cover
Tightening Torque : 25 to 60 Ncm
Loosening Torque : 55 to 60 Ncm
Screw Travel : 6 mm less wire thickness
Torque greater than 60 Ncm may strip the screw or break the Safety Cover.
Worn-out bits and insufficient hold-down pressure while torquing will cause the bit to ride on
the screw head thus stripping and damaging it..
DANGER  :
All Installation, wiring and periodic maintenance of the EPM 20
00 as well as
its associated circuits involves high voltages and currents. While this
manual suggests several safety and reliability steps, it must be used in
conjunction with the safety codes in force at your location. Failure to
practice safe working pro
cedures is likely to cause damage to the
installation, severe injury and / or death. All work including handling of
electrical circuits during Installation, wiring and periodic maintenance, must
be done only by qualified personnel.
Neither GE nor its agen
ts may be held responsible for damage or death
arising out of the wiring and / or PT, CT or other external circuits.
The covers of the EPM 2000 should never be dismantled or opened. There
are no user-serviceable parts inside. The EPM 2000 contains high-p
recision
components which require special handling available only at authorized GE
service locations. High voltages are likely to be present inside even after
the EPM 2000 has been switched off. Opening the covers of the EPM 2000
and/or any attempts to dis
mantle, service, repair or modify the unit by
unauthorized persons may cause severe injury, will damage the unit and
will also render GE’s warranty void.
