A. Removing a Meter from Service
This appendix contains instructions to follow if you ever need to remove the meter
from service.
A.1: Removing the Meter
Follow these steps:
1. De-energize all circuits feeding the case.
2. If possible de-energize lines that the CTs are on.
3. Tighten all the shorting screws on all the CT shorting blocks by turning all the
screws clockwise until they bottom out.
WARNING!
If the meter must be removed from service, the
secondary side of the current transformers
MUST
be short circuited to
prevent a dangerous high voltage condition from appearing across the
secondary wires of the current transformer.
Arcing and damage to personnel and/
or equipment can occur if the screws provided on the shorting block are not
installed in the correct locations, prior to disconnecting any wires.
AVERTISSEMENT!
Si le compteur doit être enlevé du service, le côté secondaire du
transformateur actuel DOIT être court-circuité pour prévenir une condition de haute
tension dangereuse d'apparaitre dans les câblages secondaires du transformateur
actuel. La brulure d'arc et l'endommagement d'un équipement ou des blessures sont
susceptibles de se produire si les vis fournies sur le court-circuit ne sont pas installées
dans les emplacements corrects avant de débrancher les câbles.
The six screws on each shorting block are used to short the high (+) sides and the
low (-) side of the CT outputs to the brass bar that is internal to the shorting block.
The pre-installed jumper connects all lows together and to ground.
WARNING! The screws need to be screwed down until the screw makes
contact with the internal bar, enabling the bar to become electrically
common with the terminal strip, and grounded.
