Electrical diagram
Figures 8.1, 8.2, 8.3, 8.4, 8.5, shows the electrical diagrams of the
CITIZEN EP70 single chamber and double chamber oven for the 400Vac
3-N, 230Vac 3 and 230Vac 1-N versions.
N.B.
For double chamber ovens CITIZEN EP 70, version 230Vac 1-N,
due to the high total electrical absorption, you have to handle each single
chamber as one-chamber ovens, each with separate electrical supply. See
wiring diagrams Pict.8.3

Adjustment for different feed voltages
Warning! To adapt the equipment to work at different feed voltages
from that indicated on the initial set up label, three alterations have to be
made:
1) to the cabling for the resistor wires;
2) to the cabling for the feed to the control panel;
3) to the application of a new label.
Carry out three alterations with care as otherwise the equipment may be
unsafe.
8.4.1 Cabling of wires to the resistor
Disconnect the plug from the electrical feed panel. Remove the guard
from the switchboard and disconnect all the wires from the remote-control
switches’ resistors and reconnect them as shown in Figure 8.1, 8.2, 8.3,
8.4, 8.5 depending on the voltage and model.
8.4.2 The cabling for the feed to the control panel
Detach the BLUE wire from the lower remote-control switch and
reconnect it as shown in Figure 8.1, 8.2, 8.3, 8.4, 8.5 depending on the
voltage and model.
8.4.3 Attachment of new label
Stick an indelible badge with the new setting data, under the serial
number plate (Figure 4.4, Figure 4.5).
