PPA Jet Flex - Precautions with the Electrical Installation; Precautions with the Gate before Automation

PRECAUTIONS WITH THE ELECTRICAL
INSTALLATION
To avoid damage to the wiring, it is important that all conduits are correctly at-
tached to the operator. Wiring must be routed through conduits, passing internally
through the suboor, taking care that none of the wiring conduits become trapped
and damaged.
The grounding terminal must
be connected to the electrical
network grounding cable.
IMPORTANT
The device must be powered via a residual current device (DR) with
a rated residual operating current exceeding 30 mA.
PRECAUTIONS WITH THE GATE BEFORE
AUTOMATION
Before adapting the operator to the gate, check the sliding, following the instruc-
tions below:
1
st
step: Before installing the operator, check if the gate is in good mechanical con-
dition, that is, opening and closing correctly. Open the gate manually and observe
the eort required. This eort must be minimal over the entire path length.
2
nd
step: Close the gate manually and check if the eort exerted was the same as
in the previous operation.
The gate must have a strong structure and, as far as possible, one that does not de-
form. The pulleys must have a diameter that matches the dimensions of the gate,
be in perfect running conditions, and be mounted so that the gate leaf has stability
throughout its movement. We recommend pulleys with a minimum diameter of
120 mm.
The gures below represent the two types of rails and pulleys used. The system that
uses a straight section (Figure A – angle bracket) has greater friction and, conse-
quently, more signicant wear. The circular section (Figure B) allows for better gate
movement and less friction for the operator.
