Sel SEL-WCS Assembly instructions
Date Code 20191029 SEL-WCS Wireless Current Sensor Installation
CAUTION
Configure the SEL-WCS prior to installation. See the SEL-734W and SEL-WCS Field Reference Guide
for details.
Install the SEL-WCS on a distribution line by using an industry-standard shotgun stick.
Step 1. Determine the normal direction of current flow. Plan to install the
SEL-WCS upstream from the capacitor bank with the attached arrow label
pointed downstream towards the capacitor. The sensors are directional, so
they must be oriented in this way to function properly.
Step 2. Use a shotgun stick to grasp the hook eye on the side of the SEL-WCS, and
place the device on the line so that the opening hangs over the line.
Step 3. Apply slight downward pressure while pulling the shotgun stick toward
you until the device is closed around the line.
The spring mechanism should be pushed in, so that it wraps around the line.

Step 4. Apply slight upward pressure until the device is secured around the line, as
shown in Figure 3.
Step 5. Use the shotgun stick to adjust the transmitter orientation so that it is
directly vertical. This is important to ensure the best propagation character-
istics for the internal antenna.
Regulatory Information
The SEL-WCS is approved for use only with specific output power configurations
that have been tested and approved. Modifications to the SEL-WCS, the SEL-734W,
the antenna system, and the power output that have not been explicitly specified by
the manufacturer are not permitted and may render the radio noncompliant with
applicable regulatory authorities. The radio equipment described in this manual emits
radio frequency energy. Professional installation is required.
United States (FCC)
This device complies with part 15 of the FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Canada

WARNING
Operator safety may be impaired if the device
is used in a manner not specified by SEL.
AVERTISSEMENT
La sécurité de l’opérateur peut être compro-
mise si l’appareil est utilisé d’une façon non
indiquée par SEL.
DANGER
Contact with instrument terminals can cause
electrical shock that can result in injury or
death.
DANGER
Tout contact avec les bornes de raccordement
de l’appareil peut causer un choc électrique
pouvant entraîner des blessures ou la mort.
DANGER
Install Wireless Current Sensor and sensors in
accordance with normal safe operating proce-
dures. These instructions are not intended to
replace or supersede existing safety or operat-
ing requirements. Only trained qualified per-
sonnel with knowledge of high voltage safety
should install or operate fault transmitters.
DANGER
Installer capteur de courant sans fil les cap-
teurs de défaut conformément aux procédures
normales d'utilisation en toute sécurité. Ces
instructions ne sont pas destinées à remplacer
les exigences de sécurité ou de fonctionne-
ment existantes. Seul le personnel qualifié,
avec formation en sécurité haute tension, doit
installer ou utiliser des émetteurs de défaut.
CAUTION
Although the power level is low, concentrated
energy from a directional antenna may pose a
health hazard. Do not allow users to come
closer than 23 cm (9 in) to the transmitter
when it is operating.
DANGER
Bien que le niveau de puissance soit faible, la
concentration d'énergie provenant d'une
antenne directionnelle peut présenter un
risque pour la santé. Ne pas permettre aux uti-
lisateurs de s'approcher de moins de 23 cm de
l'émetteur lorsqu'il fonctionne.
