Installing The Control Box; Technical Data - Chamberlain LiftMaster Professional CB2 Manual Del Usuario

This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage
to property. Please read these warnings carefully.
This drive is designed and tested to offer appropriate safe service provided it is installed and operated in strict accordance
with the following safety rules.
Failure to comply with the following instructions may result in serious personal injury or property damage.
It is important to make sure that the gate always runs
smoothly. Gates which stick or jam must be repaired
immediately. Employ a qualified technician to repair the
gate, never attempt to repair it yourself.
When using tools and small parts to install or carry
out repair work on a gate exercise caution and do not
wear rings, watches or loose clothing.
Installation and wiring must be in compliance with your
local building and electrical installation codes. Power
cables must only be connected to a properly earthed
supply.
Make sure that people who install, maintain or operate
the gate drive follow these instructions.

Control unit CB2 is designed to be installed in a special box
under the cover of the sliding gate drive and if this box is not
available it can be ordered as an accessory. The control unit can
also be installed externally (wall mounted) or in a watertight box
(accessory).
WIRING
The control unit must be connected up last, i.e. after the drive has
been installed, laying the required cables and mounting the light
barriers (contact strip). If the control unit is permanently installed,
means of isolating the system from the mains supply must be
provided. The contact spacing used in this means (isolating switch)
must be at least 3 mm.
Humidity and water will damage the control unit. Always make sure
that water, humidity and condensation cannot enter the control unit. It
is vitally important that all openings and cable entries are sealed so
that they are watertight.

INSTALLING THE CONTROL BOX

The motor control unit comprises an electronic microprocessor-control
system employing the latest technology. It has all the necessary
connection facilities and functions to ensure safe operation. Fit the
control box containing the motor control unit with the cable entry at
the bottom. It must not be continuously exposed to direct sunlight.
Thanks to the electronic control unit, fine adjustment of the push-pull
torque is possible. When correctly installed/adjusted, gate movement
can be easily stopped by hand.
When the gate is moving, it can be stopped at any time by radio,
pushbutton or key-operated switch.
For the OPEN and CLOSED positions, the gate requires a stable end
stop.

Please remove any locks fitted to the gate in order to
prevent damage to the gate.
Disconnect electric power to the gate drive before
making any adjustments.
Keep accessories away from children. Do not allow
children to play with pushbuttons or remote controls. A
gate can cause serious injuries as it closes.
Keep these instructions in a safe place so that you can
refer to them quickly when you need to.

Generally speaking, the following minimum cable cross-
sectional areas must be adhered to:
• 100-230Volt 1.5mm
• 0-24Volt 0.5mm 2 or more
Tips: Bell wire is often problematic in practical use because it loses
too much voltage if long lengths of wire are used. Segregate the
cables in cable trunking, i.e. motor cable and light barrier cable,
especially in the case of key-operated switches and ON switches
(from the house wiring system) to prevent interference where long
lengths of cable are used.
