The Phillips Screw Terminal Block, located on the bottom of the unit, 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.
The iES12G series supports dual redundant power supplies (PWR1 and PWR2). There are 3 options:
•
LV: Dual Input 10-48VDC
•
MV: Single Input 36-75VDC with Single 10-48VDC Backup,
•
HV: Single Input 110-370VDC or 90
-
264VAC with Single 10-48VDC Backup
There are also connections for the Failsafe Relay. The Failsafe Relay is rated 1A @ 24VDC. Connections
to the Terminal block are listed in the table below.
