MPG-2
Premium Solid State
MOUNTING POSITION -
The MPG-2 may be mounted in any position but is intended to be mounted with the
hinged door on the left such that the circuit board is upright. The MPG-2 must be mounted within 25' line-of-site of
the meter. Actual operational distance may vary with building construction and ability for the RF signal to penetrate
building materials. For best results, mount the MPG-2 as close to the meter as reasonably possible.
POWER INPUT -
For 120VAC, connect
120VAC
"hot" lead to the 120V terminal. Connect the neutral wire to the
NEU
terminal. For 208 to 277VAC, use the
277V
terminal for the "hot" lead and the
NEU
terminal for the neutral
power supply lead. The
EGND
terminal MUST be connected to the power supply ground. If the MPG-2 is mounted
at the meter and powered from the meter potentials, AND no true neutral exists at the meter, connect the EGND
and NEU terminals to the electrical system ground.
ZIGBEE WIRELESS COMMUNICATION -
The MPG-2 is designed to receive power monitoring information from
an electric meter equipped with Zigbee wireless communications. The Zigbee transceiver dongle is mounted on
the MPG-2's circuit board and may be secured with a tyrap. Ensure that the dongle is properly seated in the USB
host socket. Do not remove.
CUSTOMER OUTPUTs -
The customer's outputs are located at the bottom of the MPG-2 board in the customer
compartment. There are two KYZ Form C (3-wire) dry-contact outputs for watt-hour pulses, and one End-of-
Interval (EOI) KY Form A (2-Wire) pulse output. The two 3-wire isolated pulse outputs are provided on the MPG-2,
with output terminals K1, Y1 & Z1 and K2, Y2, & Z2. The End-of-Interval pulse output uses terminals T1 & T2.
Transient suppression for the contacts of the solid-state relays is provided internally. The output loads should be
limited to 100 mA at 120 VAC/VDC with maximum power dissipation of each output limited to 800mW.
FUSES -
Fuses are 3AG fast-blow type. One-fourth (1/4) Amp fuses (the maximum size) are supplied
standard. The KYZ outputs for Output1 and Output 2 are protected by fuses F1& F2, respectively. The EOI
output is protected by fuse F3.
