Power Connections
The iES6 and iES6-S Series Ethernet switch supports 3 different dual redundant power supplies (PWR1 and
PWR2):
1.
LV: Dual Input 10-48VDC
2.
MV: Dual Input 36-75VDC
3.
HV: Single Input 85-264VAC or 88-370VDC with a Single 10-48VDC Backup.
Figure 8 - Power Connection
The label on the terminal block will indicate the accepted voltage range for PWR1 and PWR2. Positions 2,
4 and 6 are all for ground connections (connected via a removable jumper) and can be used for any ground
connection. The 3 tables below list the power connections for each type of input power.
The Phillips Screw Terminal Block has Phillips screws with compression plates, allowing either bare wire
connections or crimped terminal lugs. The use of #6 size ring lugs is recommended to ensure secure and
reliable connections under severe shock or vibration. The terminal block comes with a safety cover which
must be removed before connecting any wires. This cover must be re-attached after wiring to ensure
personnel safety.
