Checks to be Performed Before Installation
!
WARNING
Before the installation it is mandatory to check if the nameplate associated to the
extension for additional entry specifies the appropriate degree of protection and ambient
temperature limits as requested by the Rules applicable to the plant/location where units
are installed.
If ELBS-20 device is purchased separately, please proceed as follows before its installation:
1.
The electrical supply cables must be suitable for the power rating (see the
certificates delivered with the ELBS-20, if available, or the ELBS-20 nameplate);
2.
Gather the necessary tools for the assembly and setting of the ELBS-20 controls;
If a long storage period has occurred, before installing the ELBS-20, please:
a.
Check the installation of the plugs or cable glands on the cable entries.
b.
Check whether the enclosure covers of the ELBS-20 body are cracked
or broken.
c.
Check the status of the Batteries.
3.
Verify that the fixing elements (screws, nuts etc.) used for fastening the
ELBS-20 cabinet can sustain at least four times the weight of the ELBS-20 unit;
Example: for the EJB-51 cabinet (Al) the fixing elements must be able to sustain at
least 160 kg.

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.
Follow the procedure describes at Section 12 “Battery Maintenance”.
