36 | IPS-4 Zone1/Analyzer
Connecting I/O Signals, Alarm Relay Contacts, and
AC Power
The analog input/output signals, alarm relay contacts, and AC power
requirements are specific to each analyzer installation.
For AC electrical supply cable and conduit requirements, refer to –
and comply with – local wiring regulations and electrical codes for the
area.
Refer to the “Electromagnetic Compatibility (EMC)” page in the con-
tents section of this manual for information that discusses the EMC
Directive regarding techniques and wiring practices to be followed.
Electrical Connections
Termination points for power and all signals are located in the Disconnect
assembly enclosure. Six metric M32 straight thread conduit entries are
provided (three on the bottom of the enclosure and three on the side) for
power, relay, and signal wiring. We recommend that three be used, but all
six may be used if needed. 3/4” NPT conduit adaptors are available from
AMETEK. Note that unused holes must be plugged with M32 hole plugs.
Do not use 3/4” NPT hole plugs with thread adapters. Only properly
certified conduit connectors must be used. WIRING SEALS MUST BE
LOCATED AT THE WALL OF THE DISCONNECT ASSEMBLY ENCLO-
SURE. NO ADDITIONAL ENTRIES CAN BE ADDED TO THE DISCON-
NECT ENCLOSURE WITHOUT VOIDING THE CERTIFICATION.
Figure 7 illustrates the general locations of all customer termination
points, while the Customer Connections drawing specifically details
the signal, relay contact, and AC power connection points. This
customer-specific drawing is located in the “Supplemental Informa-
tion” tab of this manual and in the Documentation Package shipped
with the analyzer.
To make the signal, relay contact, and AC power connections:
1. Open the Disconnect Enclosure.
If a power-disconnect switch (breaker) was installed, open (turn off)
the breaker before making the AC power connections. AC Power and
relay connections are made at the AC Disconnect board.
2. Route the analog input/output signal wiring and alarm relay contact
conductors through one of the Signal cable entry ports and into the
Disconnect Enclosure.
