Ungrounded Wye Banks
Installation consists of several operations. The details of these operations, and the order
in which they must be carried out, depend on the type of control device, and on local
or customer codes, standards, and procedures. The following information is specifi c
to BankGuard Plus Controls protecting
ungrounded wye-connected capacitor banks .
The required fuse blocks and fuses are furnished with the control device, and you must
install them. When you design the installation, be sure to provide adequate ventilation;
the temperature near the control device should not exceed 160°F. This is particularly
important when the control is installed in a cabinet or when several controls are installed
close together.
Step 1
Read and make sure you understand the following warnings before you begin
installatin or operate this equipment.

WARNING
These instructions do NOT replace the need for utility operation standards. Any
conflict between the information in this document and utility practices should be
reviewed by appropriate utility personnel and a decision made as to the correct
procedures to follow.
Serious risk of personal injury or death may result from contact with electric
distribution equipment when electrical isolation and grounding procedures are not
followed. The equipment described in this document must be operated and main-
tained by qualified persons who are thoroughly trained and understand any hazards
that may be involved. This document is written only for such qualified persons and
is not a substitute for adequate training and experience in safety procedures for
accessing high voltage equipment.
This control is connected to capacitors operating at primary voltage levels. High
voltage may be present in the wiring to the control or the control itself during cer-
tain failures of the capacitor bank wiring or system grounding, or due to a failure
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 accessing other high
voltage lines and equipment. Follow all locally approved safety procedures when
working on or around this control.
Do not energize the control power source entering the control enclosure until all
wiring is complete.
Ç
WARNING
Do not enable communications by connecting radios, fiber optic cables, or dedicated
phone lines until this is called out in the instructions.
Before attempting to access an existing installation, check carefully for visible
or audible signs of electrical or physical malfunction (do this before touching or
operating the BankGuard Plus 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 insure a safe and successful BankGuard Plus Control installation.
