Cable Entry; Ifm24160 Module Wiring; Battery Connection - INIM Electronics Previdia 216 Manuel D'installation

Installation manual

4.2.1 Cable entry

Refer to Figure 5 - Previdia216 - a.
Use only the provided cable entries (remove the respective cable-entry seals) on the upper and lower parts of the cabinet
and on the back [A].
The cables must run vertically behind the grounding bar (paragraph 3.1 - [L]) and must be secured to the appropriate
hooks by cable ties [B].
The cable must run level with the terminal board of the module it is to be connected and its shield must be connected to
the grounding bar [C]. Conductors without shields must be conveyed to the appropriate terminal board [D].
The unused cable entries must be closed by the supplied plastic seals.
4.2.2Mains connection
Refer to Figure 6 - Previdia216 - b.
A dedicated input [A] must be provided for the mains power input terminal (230-115V~). The cable must be secured to
the appropriate hooks by a plastic cable tie in order to avoid accidental dislodgement [B]. The cable must be protected
by a ferrite (supplied) which must be affixed in the proximity of the terminals [C].
Ensure that the network cable runs along a separate path and that it does not interfere with any other cables.
This panel must be connected to a separate line on the Electrical Switchboard (Mains power supply). The line must be
protected by a sectioning device which must be labeled and of "16A curve C" type.
The installation must be constructed, arranged and installed in compliance with the local laws in force regarding
electrical safety.
Cables:
Connection cable type NYM 3 x 1.5 mm
Protected by ferrites (supplied)
4.2.3Connection of system grounding conductors
Refer to Figure 7 - Previdia216 - c.
Connect the mains earth conductor to the screw that must be inserted in the proper hole of the IFM24160 power-supply
module ( , [A], paragraph 3.3 - [I]).
The earth conductor must be connected to earth on the electrical panel which supplies the control panel.
The grounding bar ([B], paragraph 3.1 - [L]) diverts undesirable current to ground in order to protect the control panel and
its peripherals. Therefore, to ensure proper functioning, make certain that the ground bar is properly connected to:
• the wire with eyelet terminal, by means of the appropriate hole ([C], paragraph 3.3 - [J]); this wire must be connected
to the IFM24160 module earth terminal (
• the internal modules, by means of the appropriate screws [E]
• the front plate, by means of the wire ([F], paragraph 3.1 - [C]) coming from the soldered end to which the ground wire
of the FPMCPU ([G], paragraph 3.2 - [G]) must be connected to.
• the cable shields, by means of cable-gland screws [H].
4.3

IFM24160 module wiring

As well as the terminal board for the mains power supply and the connector for the batteries, the IFM24160 power-
supply module also provides two supervised outputs capable of supplying 27.6V in active status and a relay (voltage-free
contacts C,NC,NO).

4.3.1 Battery connection

Refer to Figure 8 - Previdia216 - d.
The batteries must be connected to the IFM24160 module by means of the supplied wire. The wire comprises the
connectors for the battery terminals and thermal probe (NTC) for temperature-based charge voltage compensation.
1. Insert the batteries into the battery compartment inside the cabinet (paragraph 3.1 - [M]).
2. Using the battery wire ([A]), connect the batteries together.
