Three-Phase Power Module
Style IQM3PPM (66C2113) IL17568
Eective January, 2000
THE MODULE
The Three-Phase Power Module (IQM3PPM) is
designed for use with the IQA6400/IQA6600 (66d2045)
and DP4000 (66d2040) meters in three-phase
applications from 100Vac to 600Vac.
In applications using either the IQA6400/IQA6600 or the
DP4000/DP4100, supply power can be drawn directly
from the three-phase line-to-line voltage.
The IQM3PPM may also be used in certain applications
of the IQA6000/6200 (2d82302) or DP4000/DP4100
(4d13110) where the NEU terminal is grounded. These
applications include three-wire applications and
applications with potential transformers (PT’s). In either
of these acceptable retrof it applications, the NEU to
GND potential at the meter terminals is zero.
INSTALLATION
This device is designed to be installed, operated, and
maintained by adequately trained personnel. These
instructions do not cover all details, variations, or
combinations of the equipment, its storage, delivery,
installation, checkout, safe operation, or maintenance.
Care must be exercised to comply with local, state, and
national regulations, as well as safety practices, for this
class of equipment.
REMOVE ALL POWER FROM (DE-ENERGIZE) THE
DEVICE TO WHICH THE POWER MODULE IS BEING
ATTACHED OR WIRED; OTHERWISE, SERIOUS OR
FATAL PERSONAL INJURY AND EQUIPMENT
DAMAGE MAY RESULT.
REMOVING EXISTING POWER MODULE
Disconnect all power to the existing meter, including
power to any relay contacts of the device. Clearly mark
all wire connections. Then, disconnect all wires from the
existing power
module. Refer to Fig. 2 and your meter’s
technical manual.
Unscrew the plug lock assembly on the ribbon cable
from the meter chassis and remove the cable from the
power module connector. Carefully remove the two
shoulder screws that secure the power module to the
chassis.
BE PREPARED TO SUPPORT THE POWER MODULE
ONCE THE SCREWS HAVE BEEN REMOVED.
MOUNTING TO IQ ANALYZER OR DP4000
Place the Three-Phase Power Module in its mounting
position on the rear of the meter chassis, in the same
position as the one removed. Replace the two shoulder
screws to secure the IQM3PPM. Reconnect all wires to
the IQM3PPM and meter - tighten all screws.
