Connecting the Electrical Supply Source
to the Enclosure
115V Models
Simply connect the 115V power cord supplied to the IEC electrical supply
plug on the back of the enclosure, then connect the integral blower power
cord from the motorized impeller outlet on the exhaust to the back of the
upper light control panel. If operating at 50 Hz operations, integral blower
performance maximum airflow will be reduced by 17%. See Figure 3-4 on
the following page.
For the remote blower used for Protector Work Stations, follow the wiring
diagram in Appendix C and wire the remote blower wires to the switched
outlet on the back of the upper light control panel. These wires are
switched by the blower switch. Refer to Figure 3-5.
The maximum circuit load for the blower is 6 amps. The lights and airflow
monitor are powered from a standard duplex electrical receptacle located
nearby for connecting the power cord. All wiring for the Protector Work
Station should be performed by a licensed electrician and conform to local
codes. In most cases, the remote blower Protector Work Station for use
with a remote blower will require the use of an additional power cord
routed from the switched power outlet on the back. See Figure 3-5 and
power cord, item 24 in Figure A-2. Modify the power cord, item 24, in
Figure A-2 for connection to the remote blower via a customer supplied
junction box located nearby. The grounding connection shall not be made
to the terminal box cover of the remote blower. The building electrical
supply system for the remote blower should include overload protection
such as a switch or circuit breaker in close proximity and within easy reach
of the operator. The switch or circuit breaker shall be marked as the
disconnecting device. Consult NEC-2002 for proper installation.
