Meter Installation in 4838 Reactor Controller
1. Unplug the power cord of the 4838 controller. Remove the (2) screws located on the
top/front cover at the rear corners of the controller. Gently lift the cover forward, which is
hinged at the bottom, taking care not to apply tension on any internal wiring.
2. If applicable, remove and discard the black
hole plug on the sloped front panel. This can
be done by pinching the clasps on the back of
the plug from the inside of the front plate.
3. Insert the meter (2082E) through the panel
cutout, from outside in, making sure the
rubber gasket is on the outside of the
controller front panel. (If wires are preinstalled, remove the terminal connector by releasing
the tabs on the sides of the module and gently pulling the terminal connector off. Reference
photos below.) Slide the white mounting bracket onto the module with the mounting screws
pointing towards the front panel. Slide the mounting bracket forward until it touches the
controller panel. The clasps on the mounting bracket should align with the groves on the
module. Gently tighten the screws until the module is held into place. (If removed, reattach
the terminal connector.)
