2.1 Mounting
The GSC400 gen-set controller must be properly mounted for safe operation.
Caution must be taken at the installation site to make sure the site is free from
excessive moisture, fluctuating temperatures, dust, corrosive materials etc. The
controller should be safely mounted in a secure
location using the 3 mounting screws provided.
See Figure 2 for the mounting locations.
Mounting screws must be installed with a torque
of no more than 7 inch pounds. Ensure that all
wiring to the GSC400 are self-supporting. Do not
allow wiring or harnesses to hang from the
GSC400 or to place excessive force on its
terminals. Keep wiring loose and use strain relief.
Figure 3 below gives the dimensions of the
mounting hardware.
To reduce the possibility of electrical interference,
