WARNING!
ELECTRIC SHOCK HAZARD!
The AC power switch (sometimes referred to as the
dispenser power switch or the iGEM power switch)
inside the electronic head shuts off power to all
components, except for the AC line voltage going to
J8 on the dispenser connection board and leaving
the board at J56 going to the switch. For this reason,
before working in proximity to the connection board,
be sure to turn off power to the dispenser at the circuit
breaker inside the building. Failure to remove the
power may result in severe injury or death.
WARNING!
ELECTRIC SHOCK HAZARD!
More than one disconnect switch may be required to
de-energize the dispenser for maintenance. Use a
voltmeter to make sure ALL circuits in the dispenser
are de-energized. Failure to do so could result in se-
rious injury or death.
When corrective actions require the electrical power
to the equipment be ON. Use wiring diagrams, con-
nector drawings and a voltmeter, and other informa-
tion in this manual to identify the electrical connec-
tions and AVOID contact with the electrical power.
Failure to do so could result in severe injury or death.
