AUTION

To ensure safety of personnel, Positron recommends following these guidelines:

 

Q

Each Chassis of an installation must be permanently connected to earth 
using the ground lug on the front of the Chassis.

Q

The field wiring should include a readily-accessible disconnect device. 
The disconnect device shall disconnect both poles (RTN and Live).

Q

This equipment must be located in the same immediate area (such as 
adjacent cabinets) as the equipment it is powering.

Q

There shall be no switching or disconnecting devices in the earthed 
circuit conductor between any Chassis of an installation and the point of 
connection of the earthing electrode conductor.
