Installation
The remote color change box is designed to be used inside a hazardous environment, such as a spray
booth, however, the Zener barrier box must remain with the GEMS control in the non-hazardous area.
Mount the barrier box to the GEMS mast as described below.
Mount the barrier box to the GEMS mast using the
mounting bracket and supplied bolts and nuts, as
shown.
Installation should be performed by a qualified electrician. Improper installation could create a
spark, resulting in fire or explosion.
