Paloma MIC-180 - Manual (Page 5)

• Use only a power outlet with a ground terminal.
• Keep any excess length of the power supply cord on the outside of the manifold
controller.
• If local codes require hardwiring of indoor installations or if the manifold controller will
be installed outdoors, see instructions below for “Hardwiring the Electrical Connections”.
HARDWIRING THE ELECTRICAL CONNECTIONS (OUTDOOR or INDOOR Installation):
• Wiring should be carried out by a qualified electrician in accordance with local codes.
• The electrical power supply requirement for this manifold controller is 120VAC/60Hz, 3
Amps.
• The manifold controller must be grounded.
• A green screw is provided in the junction box for grounding connection.
• Remove the power supply cord and install the connector for the hardwiring (supplied) to
allow hardwiring at the junction box.
• DO NOT connect grounding wire to water pipes, gas pipes, telephone cables, lighting
conductor circuits and to grounding circuit of other equipment that carry a ground-fault
interrupter.
• An ON/OFF switch must be provided and installed for incoming 120VAC power.
