Wires Dimensions
Before making any connection with the ELBS-20 checks the electrical parameters present
(voltage and current limits) on the nameplate and in this manual. All the connections are
available on DIN RAIL TERMINALS; the ones with the sensors are usually at Biffi’ care).
Max dimension of the wires: 2.5 mm
2
for the standard DIN Rail Terminals.
The dimension of the wires must respect the current regulations of the installation country.

Unused entries
!
WARNING
Replace the plastic plugs, install on the unused entries certified explosion-proof
plugs and block with a thread sealant to guarantee the tightening. Not performing
the above prescription will invalidate the safety protection in case of presence of
hazardous atmospheres.

Start-up Procedure
!
WARNING
If the device is located in hazardous area a "hot permit" must be obtained before
opening the explosion proof enclosures. Moreover, the area must be cleaned from
explosive mixture since batteries and power supply could generate electrical spark and
cause explosion.
In this section is described a step-by-step procedure for installing the ELBS-20.
All the points must be performed in the order they appear.
1.
Configure the SLEEP Operating Mode.
This operation must be performed before
connecting the ELBS-20 (pneumatic or hydraulic and electrical connections) for
avoiding that the ELBS-20 is in an operating mode that can cause a not desired
Safety Action (VC or VC + ACQ).
a.
Verify that the ELBS-20 connections (hydraulic or pneumatic and
electrical) do not allow to the ELBS-20 to perform the Safety Action.
b.
Apply a supply source to ELBS-20: Battery Pack (see Section 10.3) or
External Power Supply.
c.
Use the Local Operator Interface for setting the SLEEP Operating Mode if it
is not already set.
2.
Connect the ELBS-20 according to the Wiring Diagram.
a.
Realize the hydraulic or pneumatic and electrical connection according to
the Wiring Diagram.
3.
Configure the ELBS-20 parameters.
This operation can be performed by
using the Local Operation Interface or one of the other available Interfaces of the
ELBS-20 (they must be enabled by using the Local Operator Interface).
