Securely Positioning The Machine; Commissioning The Machine; Power Supply - Leister SEAMTEK 900 AT Operating Instructions Manual

The machine must only be operated at an altitude of up to max. 2,000 m above sea level. We cannot guarantee that the machi-
ne will function properly if it is used at a higher altitude.
Furthermore, ensure that the machine is only operated in conditions with a maximum humidity of 95% and a maximum tempe-
rature of 45 °C. Individual components of the machine may no longer function properly if it is still used above these limits.
The operator should work in front of the machine on a height-adjustable chair. This allows the operating personnel to correctly
view the welding point and therefore prevents postural problems.
The machine must always be used with gloves to protect against the hot
temperatures.

Power Supply

Connection Plug
The machine must be connected to a residual current circuit breaker. Residual current protection devices prevent dangerously
high ground currents and help reduce the number of life-threatening electrical accidents.
Power Supply Connector Plug
The Seamtek 900 AT is supplied without a connector plug. Connect a plug that guarantees the specifications of the machine
and complies with all statutory requirements specified in the respective country.
The following specifications regarding the current source and the connector plug must be observed.
Nominal voltage
Frequency
Nominal current
Power supply cord and extension cable
• The nominal voltage specified on the device must match the supply voltage.
• The cable for the power connection for the machine (22) must be freely movable and must not impede users or third parties
during work (tripping hazard) see picture 6.2.
• The extension cables must be permitted for the utilization site and be marked accordingly. Take into account the necessary
minimum cross-section for extension cables as required.
V 230 – 240
Hz 50 / 60
A 20
The machine must be placed on an even substrate.
Turn all four feet (6) downward (anticlockwise
direction of rotation) until the machine equally rests
on all feet (6) and is suitably and securely posi-
tioned. Use a spirit level to align the machine.
