Connection Of The Cables To The Base - Stahl EC-940-PTZ-HF Série Manuel D'instructions

7.3 Connection of the cables to
the base
CAUTION! The electrical system to which the
unit is connected must be equipped with a
15A max automatic bipolar circuit breaker.
The minimum distance between the circuit
breaker contacts must be 3mm (0.1in).
The circuit breaker must be provided
with protection against the fault current
towards the ground (differential) and the
overcurrent (magnetothermal).
A power disconnect device must be
included in the electrical installation, and
it must be very quickly recognizable and
operated if needed.
Before doing any technical work on the
device make sure that the power supply is
disconnected.
The device can only be considered to be
switched off when the power supply has
been disconnected and the connection
cables to other devices have been removed.
Be careful not to use cables that seem worn
or old.
Use suitable cables that can withstand the
operating temperatures.
The connection compartment lid can
be opened only for cabling the device.
The other lids must be opened by the
manufacturer only.

A connection compartment for cable entry with a
3/4" NPT threaded hole is located on the base of the
unit.
A threaded cap gives access to a connection board
with removable connectors that help the installer to
connect the cables.
The safety grub screws are used to prevent
the unscrewing of the threaded lid from the
connection compartment. Remove both
safety grub screws before unscrewing the
threaded lid.
Carry out the connections removing the safety grub
screws (01), the threaded lid (02) and the plastic cap
(03).
The plastic cap is only used during transportation and
cannot be used when operating the device.
