1 SAFETy
The mains cable may only be connected to a mains
socket with a protective earth that is connected to
nearby earth and earthed objects. Check with the
nominated person in control of work activity that the
systems are connected in accordance with local safety
regulations.
If separate earthing cannot be discounted: one of the
following methods may be used, on the condition
that local safety regulations are observed:
„ „
connect the earth systems temporarily
„ „
use a (portable) electrical power source
„ „
use an isolating transformer; the secondary side's protective
earth must not be connected to the primary side's earth
Remove earthing (ground) at one side
Removing of earthing (grounding) at one side must
be done in accordance with local safety rules. When
only one side of the circuit breaker is connected to
earth (ground), two important rules must be followed
closely to protect service personnel and measuring
equipment from hazardous voltages:
„ „
The TM1800 case must remain earthed (grounded) by the
separate protective conductor
„ „
Connections or disconnections of test cables may not be
made at the Circuit Breaker
