Making Electrical Connections
TC110 Series systems are designed for three-phase voltage operation. Refer to the unit
nameplate for proper voltage and amperage requirements.
Make sure you provide a correctly sized and protected supply of electrical power to the
unit.
Important!
Refer to Local Electric Codes
for proper feeder conductor and supply disconnect sizing.
Maintain a safe ground and disconnect the power supply before servicing the unit. A
qualified electrician should make electrical connections, and disconnect and lock out
electricity using OSHA 29CFR 1910.147 standards when you need a service call.
Check serial tag voltage and amperage requirements and make sure your electrical service
conforms before making any electrical connections. Total running amps for TC110 Series
systems are listed on the nameplate. Customer connections can be run to the supply
terminals from either side of the unit. Make sure that all three phases are wired correctly. If
not wired properly, the unit will run backwards. Again, check the unit nameplate for correct
voltage and amperage.
Improper electrical connections
can damage the unit and cause
serious operator injury or death!
Bring properly sized power leads and ground from a fused disconnect
(installed by your electrician) to the unit. Provide external overcurrent
protection to the unit, using circuit breakers or fuses. If you use fuses,
make sure that they are dual-element time-delay fuses, sized according to
your electrical code. Make sure that all electrical connections are tight.
