Note: Recommended fusing is 4 A fuse.
IMPORTANT: 4 A fuse is calculated without BOUT consumption nor extension modules. Real value
of fuse depends on consumption of binary outputs and modules.
Example: Maximal consumption of binary outputs can be 22 A
2 x 10 A on high current outputs (for 10 seconds)
2 A on all others binary outputs
4.4.4 Measurement wiring
Use 1.5 mm
2
cables for voltage connection and 2.5 mm
2
for current transformers connection. Adjust Connection
type (page 176), Nominal Voltage Ph-N (page 177), Nominal Voltage Ph-Ph (page 177), Nominal Current (page
175), Bus VT Ratio (page 177) by appropriate setpoints in the Basic Settings group.
IMPORTANT: Risk of personal injury due to electric shock when manipulating voltage terminals
under voltage. Be sure the terminals are not under voltage before touching them.
Do not open the secondary circuit of current transformers when the primary circuit is closed. Open
the primary circuit first.
Current measurement wiring
The number of CT’s is automatically selected based on selected value of setpoint Connection type (page 176)
[3Ph4Wire / High Leg D / 3Ph3Wire / Split Ph / Mono Ph].
Mains currents and power measurement is suppressed if current level is bellow <1 % of CT range.
To ensure proper function:
Use cables of 2.5 mm
2
Use transformers to 5 A
Connect CT according to following drawings:
