Figure 17. Wiring Access
This unit is provided with an electrical
junction box in the rear panel for main
power connections. See Figure 17.
All power wires are factory installed
between this junction box and the main
high voltage box at the front of the
unit. The unit is available with multiple
voltage packages to adapt to customer
needs ranging from 120-600 volts with
single or 3 phase versions. Refer to the
rating plate and Table 18 for appropriate
voltage and current ratings.
As a common industry practice, the
manufacturer has color coded the single
and three phase wires as shown in
Table 19.
On single phase models, the incoming
voltage will be protected by the
appropriate circuit breaker, sized and
installed by a qualied electrician/
authorized personnel. The 120-volt and 24-volt systems
will be protected with resettable fuses mounted in the
top of the high voltage box. The 24-volt transformer
is also redundantly protected by its integrated 4 amp
resettable fuse.
On three phase models, a step down transformer (which
is protected using an appropriate din rail mounted circuit
breaker) generates 120-volt single phase to power the
7.B Main Power Connections
24-volt transformer. The 120-volt and 24-volt outputs of
either transformer are protected with resettable fuses
mounted in the top of the high voltage box. The 24-
volt transformer is also redundantly protected by its
integrated 4 amp resettable fuse.
All power connections must be run through the
back panel as shown in Figure 17.
