Reinstalling the Electronics Module
STEP 1.
Hold the electronics module by the handle at the front of the module and the tab
at the rear of the module. See Figure 6 on page 13.
NOTICE
To remove and install the control, grasp the control handle and the tab
opposite the handle . The control must be kept perpendicular to the base
when removed or installed .
Damage to the connectors could occur if the control is removed or installed
at an angle .
STEP 2.
Align the captive screws of the electronics module with the holes in the base
plate of the burden-board and push straight down gently. See Figure 7. This
connects the electronics module to the burden-board module. It also lowers the
stand-off, which pushes the current transformer shorting clip away from the
burden board, removing the short circuit from the power current transformer
secondaries. The control will power up if suffi cient current is fl owing through
the Vista switchgear. See Figure 8 on page 15.
Figure 7. Align the captive screws of the electronics module with the holes in the burden board
