The NoMax
®
900 Series Controls can be supplied ready for 4 jaw meter
socket mounting or direct pole mounting.
Installing into a Meter Socket
– Socket mounted controls are supplied ready
for either ringed or ringless meter sockets. The two types of sockets are not
interchangeable; make sure you have the correct type of control for the meter
socket to be used.
Installing into a Ringed Base
– Align the terminals on the back of the control and
press firmly into the meter socket. Use the supplied ring to complete the installation.
Attach a ground wire to the external ground lug. Seal or lock the ring only after the
entire system has been verified.
Installing into a Ringless Base
– Align the terminals on the back of the control and
press firmly into the meter socket. Tighten the 3 locking screws located on the
meter base. Attach a ground wire to the external ground lug. Seal the 3 locking
screws only after the entire system has been verified.
Installing Pole Mounted Controls
– Pole Mounted Controls are mounted with
the included pole bracket and user supplied mounting straps or lag screws.
After the control is attached to the pole, attach a ground wire to the external
ground lug. Connect the control cable from the Capacitor Bank junction box
to the 5-pin connector on the Control.
WARNING:
Before plugging the control into a live circuit, rotate the main
switch out of the “AUTO” position or remove the front panel fuse, and observe
all safety procedures for working with live circuits. Failure to comply can result
in death, personal injury or equipment damage.
