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.

CONN#1

Power supply

CONN#2

Pin 1-2 SET VALUE FOR MW POWER reference signal 

for microwave power (SetPoint).

0÷10Vdc / 0÷100% Power. No power is emitted unless you 

reach a reference signal of 1Vdc (10% power).

CONN#3

Controls. Optoinsulated signals.
