4 Electrical Connections
4.1 General
It is essential that installation, electrical connection, commissioning, operation and maintenance in
explosion hazard areas are only carried out by trained specialist staff authorised to do so by the system
operator.
The installation shall be performed according to NEC or CEC and to the Control Drawing M1_1309080
(page 51).
The installation in an explosion hazard area shall comply with EN 60079-14, EN 60079-25 or
IEC 60079-14, IEC 60079-25. Repair and maintenance shall be performed according to EN 60079-17 or
IEC 60079-17 and EN 60079-19 or IEC 60079-19.
All relevant national regulations shall be strictly observed.
Installation in the U.S. shall be performed according ANSI / ISA RP 12.6.01-2003 and
the National Electrical Code (NEC).
Installation in Canada shall comply with the Canadian Electrical Code (CEC).
The EE300Ex sensor is a loop powered (2-wire) device, both channels (outputs) are galvanic isolated.
For proper operation, Channel 1 (CH1) must always be connected. Channel 2 (CH2) may be
connected only if necessary.
Cable ends shall be fitted with the appropriate wire-end sleeves. While connected to the
terminals, the air gap must be min 2mm (0.08") between the wires and min. 6mm (0.2") between CH1
and CH2.
Do not shorten or extend the probe cable. Changing the length of the probe cable has a strong negative
effect onto the measurement performance and may lead to EE300EX failure.
