Follow the instruction below in order to prevent risk of fi re, electric accidents or inju-
ries to the personnel involved in the activity.
• Never turn on the equipment to 220 V of rated voltage if it is set to 127 V. Caution: risk of fi re!;
• Keep the equipment disconnected from the power supply while changing the voltage. Adjust/change the
rated voltage during the operation of the equipment is prohibited!
IMPORTANT
Consideration about installation
Before turning on the equipment, make sure the voltage (127 V or 220 V), phase (single phase) and frequency
(60Hz) of the power supply match the values informed on the equipment and on Table 1. Models with two volta-
ges (e.g., 127/220 V) are connected to the highest voltage. To change the operating voltage, follow the procedure
aforementioned. Do not forget to check if the power supply cable has a proper section to stand the input current
required by the equipment, as indicated in Table 1. The power supply must feature proper protection fuses and
circuit brakers. It is recommended:
