WARNING!

Some applications have electrical 
transients that can damage the EGS21
gage and leave no apparent sign of
failure. To prevent this failure mode
from affecting other systems, attach
enclosed suppression extension 
harness directly to the gage, between
the gage and the system harness.

NOTICE

The EG21 and EGS21 series 
Swichgage

®

requires 12VDC to operate.

To support 24VDC and 32VDC systems, 
the harness is specifically designed to 
convert the supply voltage to 12VDC to 
operate the gage.
