Installation
Safe operation depends upon proper installation. Before
startup, ensure the following:

Connections and Jumper Position
The included jumpers must be properly positioned for the
primary voltage. Secondary voltage is reduced to either 1/4
(Figure 1) or 1/2 (Figure 2) of the primary voltage based on
the jumper position.

The mains are connected correctly.
Protection is provided against electrical shock.
All supply lines are sized correctly and fuse-protected.
All output cables are sized correctly for the maximum
device output current and are fuse-protected.
Sufficient air flow is provided around the devices. Allow
at least 25 mm (1 in.) between the transformer and oth-
er components.
DANGER!
Hazardous voltage. Disconnect power before
servicing.
WARNING!
High temperatures may occur during opera-
tion. Allow to cool before servicing.

Sizing a Control Panel Transformer
To select the proper transformer, three characteristics of
the load circuit must first be determined: total steady-state
(sealed) power, in VA; total inrush power; and inrush load
power factor.

Once the above circuit variables are determined, trans-
former selection is a six step process.

3.
The total, steady-state “sealed” power is the amount of
power that the transformer must supply to the load cir-
cuit for an extended length of time. Simply add the total
steady-state power of all devices in the control circuit.
The operating power data of a component is available
from the manufacturer.
The total inrush power is the amount that the trans-
former must supply for all components in the control
circuit which are energized together. Some consider-
ation to the start-up sequence may be required. Inrush
power can be obtained from the device manufacturer.
The inrush load power factor is difficult to determine
without detailed vector analysis of all the control circuit
components. Such information is not generally avail-
able. Therefore, a 40% power factor is typically as-
sumed.
Determine the primary (supply) and secondary (output)
voltage requirements, as well as the required frequen-
cy, i.e., 60 Hz.
Calculate the total steady-state power of the circuit.
Now calculate the total inrush power by adding the in-
rush power of all components being energized togeth-
er. Remember to add the steady-state power of all
components that do not have inrush power, (lamps,
timers, etc.) as they do, however, present a load to the
transformer during maximum inrush. If the inrush cur-
rents for the components in the circuit are not known,
assume a 40% inrush power factor.
