Description
The GRX-PWM provides 12 V
control and ballast switching capabilities in one enclosure. With
the GRX-PWM, a GRAFIK Eye 3000 Series Control Unit* can
control PWM ballasts powered by 100-277 V
switching relays that can handle the in-rush current for a full
circuit of ballasts. The GRX-PWM can also be used to switch any
of the load types listed below.
*GRX-PWM will also work with Lutron GP or LP panel outputs.

Mounting
Find a suitable location for mounting.
Decide on the proper location for the GRX-PWM (NEMA Type 1
•
enclosure, indoor use only). See System Wiring Layout below.
The environment where the GRX-PWM is placed must have an
•
ambient temperature range of 32-104°F (0-40°C).
Mount the enclosure vertically on a wall (screws not provided).
•
See Mounting Diagram below.
Mounting method must be able to support weight and forces
•
applied during installation.
Internal relays will click while in operation; mount where
•
audible noise is acceptable.
