Other Considerations for Hardwired Units

Three Phase Operation

If operation from a three phase source is required, three hardwired regulators

may be wired in delta as shown in Figure 4.

Note

Required branch circuit protection must be located in the primary of each

regulator, not in the three phase line. The outputs must supply three

independent single phase loads of the same voltage rating. Do not connect

loads phase to phase when the three phase configuration is used.

Multiple Operation

Two or more hardwired models of the same rating may be connected with

their input and output in parallel. However, on models smaller than 5kVA,

do not parallel both 220VCT (X1-X2-X3) and 240VCT (X4-X2-X5). This may

damage the output windings.

Input Power Switch

Because the regulators include resonant circuitry that is energized whether

or not the unit is serving a load, it is very desirable to install a disconnect

switch in the primary circuit.
