NOTE: all the models with auxiliary power supply have, mandatorily
, to be connected to external current transformers
because the isolation among the current inputs is just functional (100VAC).
Tamper proof accessory kit
The “tamper proof” kit (two scr
ew pro-
tection covers) is available with the
“PF” option.
The instrument (PF option) is sealed in
one point:
- Front selector (to lock the instrument
programming).
After installation it must be sealed in
other two points:
- Upper cover;
- Lower cover
.
Notes: * Not available with option PF A. ** Not available with option PF B
