Electrical connections
WARNING
Risk of injury due to live parts!
When the housing is open, contact protection is not provided
and EMC protection is limited.
• Before opening the housing, switch off the power supply.
Note
For electrical installation, the following standards, data, and
documents must be complied with:
• The relevant regulations and safety standards pertaining
to the installation and operation of electrical systems
• The additional regulations, standards, and directives
pertaining to the installation and operation of explosion-
proof systems, if explosion-proof units are used
• Values for the electrical connection (see chapter
Electrical Data on page 13).
• The information from explosion protection certificate, for
an explosion-proof design.
NOTICE
Adverse effect on input signals
Power supply leads in the immediate vicinity of the signal
lines produce interference which can impair the input signals
to the devices.
• Do not install the signal line together with power supply
leads.
Cable glands
The field mount housings feature a PG 11 cable entry.
Aluminum or stainless steel field mount housing
Ex Protection Cable entry
Standard / Ex ia Screw connection ½ in NPT
Ex d Threaded hole M20 × 1.5
FM / CSA ‘Intrinsically Safe’ /
‘Explosion Proof’ Threaded hole ½ in NPT
Position of the terminals
The electrical connection is provided by 2-pin screw terminals for
conductor cross-sections up to a maximum of 2.5 mm
2
(14 AWG).
Do not reverse the polarity (+/-) when connecting the signal line.
Control room housing unit for rail and block mounting
The terminals are located on the side of the housing unit.
Plastic, aluminum, and stainless steel field mount housing
The terminals are located inside the housing unit. Therefore, the
field mount housing must be opened in order to connect the
cable.
