MFM443-T
Instruction Manual
Introduction
The MFM is a panel mounted 96 x 96mm Multifunction Meter for the
measurement of important electrical parameters like AC Voltage,
AC Current, Energy, Power, Frequency and Power Factor
MFM can be configured and Programmed On site for the following :
PT Primary, PT Secondary, CT Primary, CT Secondary (5A or 1A) and
System Type 3 phase 3W or 4W or single phase system. The front panel
has Four keys using which the user can scroll through different screens
and configure the product.
Caution for your Safety
WIRING: The probe and its corresponding wires should never be
installed in a conduit next to control or power supply lines. The electrical
wiring should be done as shown in the diagram. The power supply circuit
should be connected to a protection switch. The terminals admit wires of
upto 2.5sq mm.
WARNING:
Improper wiring may cause irreparable damage and
personal injury. Kindly ensure that wiring is done by qualified personnel
only.
Maintenance: Cleaning: Clean the surface of the controller with a soft
moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.
