Cabling recommendations
String input connections (S1IN .. S8IN)
•
For 30A per string installations, 6mm² tinned double insulated fine stranded cable (fitted with
ferrules) is required.
•
Cables with lower cross-sectional area may be used for installations where less than 20A per
string can be expected.
String output connections (COMMON)
•
When ProSMS 8 is operating at full capacity (30A per string, 240A total), four 16mm
2
tinned
double insulated fine stranded cable (without ferrules) is required
•
Cables with lower cross-sectional area may be used for installations where less than 20A per
string can be expected.
String voltage measurement connections (+1000VDC)
•
At least 1mm² tinned, double insulated, fine stranded, cable with ferrules, is required.
MODBUS (GND,A,B)
•
Shielded twisted–pair cable, designed for RS485 interfacing is required. Cable should have at
least two twisted pairs with cross–section area of 0.2mm
2
(24AWG) up to 0.5mm
2
(20AVG).
•
Cable should have a characteristic impedance of 100–120 ohm for optimal performance.
Digital inputs (DIN1,DIN2)
•
Any appropriate cable up to 1mm² with ferrules, or 1.5mm² without ferrules may be used.
Digital outputs (NO,C,NC)
•
Any appropriate cable up to 1.5mm² with ferrules, or 2.5mm² without ferrules, may be used.
