The most sensible loads to voltage distortion
include incandescent lamps, discharge lamps,
computers, X-ray equipment, audio amplifiers, and
elevators.
Refer to Atlas Copco about the measures to be
taken against the damaging influence of non-linear
loads.
Cable quality, minimum sectional area and
maximum length
The cable connected to the generator terminal shall
comply with the local regulations.
Cables shall be dimensioned according to Brazilian
standard NBR 5410, considering the following
conditions:type of installation, current-carrying
capacity, working ambient temperature, limits of
network/cable voltage drop and cable length.
Voltage drop based on a known conductor sectional
area, can be calculated as follows:
Protection
For safety reasons, it is necessary to
have an isolator switch or circuit
breaker in each load circuit. Local
legislation may impose the use of
isolator devices that can be blocked.
– Check if the frequency, voltage and current
match the generator specification.
– The power supply cable length shall not be
excessive, the cable shall be arranged in a safe
way, preventing to get bent.
– Open the control panel door and that of the
indicating instrumentand the transparent door
in front of X1 terminal panel.
– Put the ends of proper cable connections on
the cable terminals.
– Release the cable fastening clip and introduce
the load cable wire ends in the hole and in the
clip.
– Connect the wires to the proper X1 terminals
(L1, L2, L3, N and PE) and tighten firmly the
screws.
– Tighten the cable fastening clip.
– Close the transparent door in front of X1.

The table below suggests the cable sectional area to
be used, according to the working model and rated
voltage.
For the below given values, shall be used EPR 130°C
cables, considering a distance up to 30 m from the
equipment supply base.
Consider 2 cables per phase
Load connection
Unit distribution panel
If there are output outlets, it shall be mounted in a
local distribution panel supplied by the generator
terminal panels and in accordance with the local
regulations in force for building installations.
