Input AC Power Module:
This module is an IEC320 interface to the mains power. The module
has an integrated switch, fuse holder and input filter module. Above
the module are the voltage, frequency and power requirements for
the product. Below the module are the fuse type and ratings based
on the input voltage used. The green light on the right side of the
module illuminates when power is ON.
O , OFF position
1 (-) , ON position
Primary Interface connection from the transformer to the unit:
This connection has all of the interfaces required to connect
current and voltage inputs from a three phase transformer into
the MTO300 unit.
Discharge Indicator – blinks every ½ second when a
transformer is discharging
Test Indicator – stays on when a transformer is energized.
Secondary/Tertiary Interface connection from the
transformer to the unit:
This connection has all of the interfaces required to connect
current and voltage inputs from a three phase transformer into
the MTO300 unit.
Ethernet Connection:
This connection links a PC used for control with the MTO300.
NOTE: port is not network compatible. DO NOT USE ON A
LOCAL AREA NETWORK. The system was designed for peer to
peer operation.
Earth/Ground Lug
This connection is used to connect a transformer under test to
earth ground for safety. The transformer and the MTO shall be at
the power ground/earth potential when being operated.
Emergency Shut Down Switch
This switch, when pushed will disable the source power supply
and automatically discharge the transformer. The instrument is
continuously monitoring this switch in the event of an emergency.
If the switch is engaged, no testing can commence.
