This explosion-protected system should be set up according to commonly accepted 
technical standards. The applicable national electrical code and safety regulations for 
your particular country must be observed.
Before commissioning the scale, a check must be carried out by or under the 
supervision of a qualified electrician to ensure that the system is in good working 
order.
Check whether or not the competent authorities (e.g., industrial supervisory board) 
need to be informed. It is also necessary to carry out inspections of the system 
during operation.
Inspection intervals should be such that any significant defects that may occur can 
be identified in good time. Inspections should be carried out at least once every 
three years. The applicable requirements and guidelines should also be observed 
during operation.
Establish a low-resistance connection from the scale and the ex-link converter 
YCO14-Z to a customer-supplied equipotential bonding conductor connection 
via the equipotential bonding conductor connections (PA) on the device using a 
suitable grounding cable with a gage of at least 4 mm

Installation must be carried out properly by trained personnel and according to
