1. Introduction
WARNING : Safety warning: the GNM 100 must never be installed in an explosive atmosphere.
This means it must be installed outside the coating booth at a minimum distance of 1.5 meters
(5 feet) from the nearest opening.
This control module is for the power units hereafter called the "high voltage units" which are fitted inside
the guns. This module is only for use with guns made by SAMES.
• The GNM module has a conductive extruded aluminium (black anodize) box, the tightness of
which conforms to protection index IP 64. Two part numbers are available:
• 858075 for all countries except the United Kingdom.
• 1516137 for the United Kingdom.
WARNING : For a use in cabinet, the room temperature must be below 45°C.
We strongly advise you not to place the GNM close to any source of heat, which would increase
its inner temperature and engender a working defect.
However, if the GNM has to be located in such conditions, provide for an air conditioning device.
The maximum temperature is 45°C for a use with a 90 KV/ 100µA high voltage unit (HVU). This
maximum temperature depends on the supplied power, therefore on the type of HVU/sprayer
which controls the GNM.
Storage temperature: 0°C to 70°C.

Signal lights:
• green = GNM 100 powered.
• orange= trigger (high voltage activated).
• red = fault.
