Brother MFC 7150C Owner's Manual page 26

Caution
The MFC must be grounded using a 3-prong plug.
Since the MFC is grounded through the power outlet, you can protect
yourself from potentially hazardous electrical conditions on the telephone
network by keeping the power to your MFC on when you connect it to a
telephone line. Similarly, you can protect yourself when you want to move
your MFC, by disconnecting the telephone line first, and then the power
cord.
Lightning and power surges can damage this product! We recommend
that you use a quality surge protection device on the AC power line as
well as on the telephone line, or unplug the lines during a lightning
storm.
