4.5 Mechanical Installation Information
4.5.1 Enclosure Dimensions
Figure 3: GG2 Detector enclosure nominal dimensions (mm)
4.5.2 Mounting Arrangements
The GG2 Detector is mounted using the custom plug interface directly to a compatible module and
secured with the integral retention clip. Optionally, the GG2 detector may be mounted up to 10 meters
away from a compatible module using the optional remote cable assembly. The remote cable assembly
allows the GG2 Detector to be installed in an appropriate position for the target gas.
4.6 Electrical Installation Information
4.6.1 Compatible Module
The GG2 Detector is a part of a GG2 range of products and is designed to interface directly with
compatible modules. Contact Ampcontrol for a current list of compatible modules.
4.6.2 Remote Cable Assembly
The GG2 detector can be mounted remotely from a compatible module using the GG2 remote cable
assembly. The cable is supplied in 10 metre lengths and may be cut to size.
4.6.3 Earthing Procedures
The metallic GG2 Detector chassis is connected to Pin 5 and compatible modules use a high integrity
multiple contact receptacle to equipotential bond the equipment’s chassis together.
The GG2 Remote sensor cable screens are also connected to Pin 5 of the GG2 Detector and bonded
to the chassis of compatible module.
The compatible modules are usually earthed at the power supply.
The GG2 Detector passes the 500V dielectric strength test between intrinsically safe circuits pins 1-4
and the metallic enclosure pin 5.
