3.5 Connecting Power
Plug one end of the power cord into its receptacle at the rear of the
controller and the other end into a wall outlet with local earth ground
(3-prong connector).
Before turning on power, the following safety checks and proce-
dures should be performed:
1. Never operate the test stand if there is any visible damage
to the power cord or the test stand itself. The ESM301 is
powered by 110V/220V. Any contact with this high voltage
can cause serious injury or even death.
2. Ensure that the test stand is kept away from water or any
other electrically conductive liquids at all times.
3. Make sure the electrical outlet powering the test stand has
local earth ground (3-prong connector).
4. The test stand should be serviced by a trained technician
only. Power must be disconnected before the controller is
opened.
