Before connecting the Midmark device power cord into an electrical
power source outlet, it is recommended to contact a local licensed
electrician or a local Authority Having Jurisdiction over the internal
building power distribution to verify that the device when powered
up will comply with all local electrical codes. Use the electrical
power rating marked on the device when determining the
appropriate electrical branch circuit and outlet requirements.
For 115V rated device models with a current rating at or above
12 Amps, a dedicated branch circuit may be required if the branch
circuit protection is provided by a 15 Amp breaker.
