Installation
Onsite Installation
Follow these steps to install the IntelliCap control at the site:
STEP 1. Read the following warnings before you install or
operate this equipment.
WARNING
This control is connected to capacitors operat-
ing at primary voltage levels . High voltage may be
present in the wiring to the control or the control
itself during certain malfunctions of the capacitor
bank wiring or grounding system, or because of a
malfunction of the capacitor bank itself . For this reason,
access to the control should be treated with the same
safety precautions that would be applied when access-
ing other high-voltage lines and equipment . Follow all
locally approved safety procedures when working on or
around this control .
When open-circuited, current transformers can pro-
duce high voltages that can result in injury or death .
Proper shorting hardware and operating procedures
are required for safe operation . The current transformer
must be shorted
before installing or removing the con-
trol . This control does NOT provide for shorting of
the current transformer .
WARNING
Do not energize the 110-240 Vac power source entering
the control enclosure until all wiring is complete .
Do not plug the sensor cable into the control until called
for in the instructions .
Before attempting to access an existing installation,
check carefully for visible or audible signs of electri-
cal or physical malfunction—do this before touching or
operating the control or any other part of the installation .
These warning signs include such things as smoke,
fire, open fuses, crackling noises, loud buzzing, etc . If a
malfunction is suspected, treat all components of
the installation, including the control and associated
mounting hardware, as if they were elevated to primary
(HIGH) voltage .
You must follow the sequence of installation steps
outlined in this instruction sheet to ensure a safe and
successful control installation .
WARNING
These instructions do NOT replace the need for utility
operation standards . Any conflict between the informa-
tion in this document and utility practices should be
reviewed by appropriate utility personnel and a decision
made as to the correct procedures to follow .
The S&C IntelliCap Automatic Capacitor Control is
connected to switchgear operating at primary voltage
levels . High voltage may be present in the wiring to
the switch control or in the switch control itself during
certain failures of the switchgear wiring or grounding
system, or because of a failure of the switch itself . For
this reason, access to the switch control should be
treated with the same safety precautions that would be
applied when accessing other high-voltage lines and
equipment . Follow all locally approved safety proce-
dures when working on or around this switch control .
Before attempting to access an existing switch
installation, check carefully for visible or audi-
ble signs of electrical or physical malfunction (do
this before touching or operating the switch con-
trol or any other part of the installation) . These
warning signs include such things as smoke, fire,
open fuses, crackling noises, loud buzzing, etc . If a
malfunction is suspected, treat all components of the
installation, including the switch control and associated
mounting hardware, as if they were elevated to primary
(high) voltage .
STEP 2.
Remove the load fuse.
Remove the 10-A fuse near the lower left corner
of the faceplate. See Figure 2 on page 10.
