Power Supply Connections
External Disconnect
• Install an external disconnect switch or circuit breaker that meets local standards
• Position the M7600 meter in an accessible location
• Position and identify the disconnect device so as to provide safe and easy operation
• Label the disconnect device as being for the mag meter
AC Power Wiring
For the AC power connections, use three wire-sheathed cable with an overall cable diameter of 0 2…0 45 inch (5…12 mm)
For signal output, use 18…22 gauge (0 25…0 75 mm
2
) shielded wire Overall cable diameter between 0 12…0 35 inch
(3…9 mm)
TO PREVENT ACCIDENTS, CONNECT MAIN POWER ONLY AFTER ALL OTHER WIRING HAS BEEN COMPLETED.
The amplifier is a microprocessor device It is important that the power supply be as “clean” as possible Avoid using power
lines that feed heavy loads: pumps, motors,
etc.
If dedicated lines are not available, a filtering or isolation system may
be required
Take national applicable rules into account
• Observe type plate (mains voltage and frequency)
• Equipment shall be provided with a external means for disconnecting it from each operating energy supply source The
disconnecting means shall disconnect all current-carrying conductors
