ABB Foundation LD 810HSE Ex - Connecting the Power Supply

16 Quick Installation Guide LD 810HSE Ex | 2PAA118721
If ambient temperatures exceed 55 °C at the place of installation, it
may occur that the temperatures of connecting cables strongly rise
if those cables have been put in place in an unfavorable condition.
In such cases, either perform measurements to conrm that the
service temperature of the cables is not exceeded (i. e. 80 °C), or
use such cable variants that withstand temperatures of minimum
90 °C.
Connecting the Power Supply
The supply voltage (18 V DC ... 32 V DC) is connected by a 3-pole terminal
block. The power supply is connected to the plug connector via exible wires
with a cross section of 0.75 to 1.5 mm². The ground connection wire must have
a cross section of 1.5 mm².
