Connecting the Grounding Cable
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
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
commonly accepted technical standards. The system should only be operated for the
first time when it is certain that the area is not potentially explosive.
If deviations are evident during startup due to transport damage (e.g. no display, no
backlighting), disconnect the scale from the power supply and contact the Sartorius
Service Center.
Connect the scale to the equipotential bonding conductor using an equipotential
bonding cable with a gage of at least 4 mm
(not included).
