Equipment installation
The GM140 cannot operate stand alone: it must be coupled
to a proper cavity by the R26 flange.
The equipment cannot operate cantilevered, it must be sa-
fely fixed vertically. If used horizzontally you must provide
a suitable support.
Handling instructions
During handling use always protection gloves. The equip-
ment doesn't have lifting eyebolts and its weight is 12 kg
(26 lbs): always lift the equipment using only the bottom of
the cabinet with a proper lifting apparatus.
Do not add any eyebolt to the cover or the front panels: they
are not suitable for lifting operations.
Wiring instructions
The GM140 must be installed and serviced only by quali-
fied personnel acquainted with the regulations covering the
application.
For safety operations the following rules must be adopted:
I) the equipment must be grounded by the connector
CONN#1 using the pin n° 4 (see the wiring drawings at
page 10 and 11);
II) the three phase main supply, type phase/phase/phase/
must be provided by connector CONN#1: phase connection
to pin 1,2 and 3, ground to pin 4;
III) the connector's pins can house wires up to 2.5 mm
2
; the
wires lenght shall be according to current capability of the
wires section;
IV) the user must provide external circuit breaker and ther-
mal cut-off. These devices must protect the GM140 from
short-circuit and thermal runaway;
V) these external protection devices must allow to switch-
off the main line for maintenance operations;
VI) the external circuit breaker must be a three poles
breaker and comply the norm EN61010-1;
VII) the external circuit breaker must be in close proximity
to the GM140 and within easy reach of the operator;
VIII) the external circuit breaker must be marked as the
disconnecting device for the GM140;
IX) the connector CONN#1 must never be used as a switch-
off device.
X) the signals must be provided by CONN#3 with 25 poles
flat cable (according to wiring diagram at page 10 and 11).
XI) the reference signal to adjust power must by provided
by CONN#2 with a 9 poles flat cable (according to wiring
diagram at page 10 and 11).
Operating Controls
The GM140 is driven through electrical signals at
connectors.
