Power supply compatibility
Product Support: www.instron.com
Frames may not be able to run at rated speeds if connected to a power supply more
than 10% below the configured voltage.
Before proceeding with installation, verify the following:
• The machine’s voltage is compatible with the main power supply of your facility.
Refer to “Determine the voltage setting” on page 34.
• The machine’s power cable can reach the electrical power supply with some slack in
the cable.
• The plug is compatible with the electrical power outlet.
If your power source is not the voltage originally specified on your purchase order, you
can follow the instructions in “Change the voltage setting” on page 34 to change the
voltage. Ensure that you use the appropriate electrical plug when changing voltages.
Hazard - Do not remove covers to any component of your system, unless it is
specified in a procedure.
There are dangerous voltages and rotating machinery inside the machine that may
cause bodily injury or damage to equipment.
Electrical hazard - to ensure safety and Electromagnetic Compatibility (EMC) the
facility’s receptacle must be a 3-wire grounded receptacle. The ground must be a
low impedance earth ground in accordance with national and/or local regulations.
The frame operates from a single-phase, two-wire grounded power source that applies
240 volts rms or less between the supply conductors or between the ungrounded supply
conductor and earth ground.
The connector on the power cable must be compatible with the power source. If the
power cable supplied with your system does not fit your power source outlet, add a male
plug to the cable that is compatible with the voltage. Observe the CEE wire color code as
follows:
• Brown - high (live)
• Light blue - low (neutral)
