WARNINGS AND CAUTIONS
WARNING: EXPLOSION RISK
Do not connect or disconnect equipment while the circuit is live or unless the area is
known to be free of ignitable concentrations or equivalent
AVERTISSEMENT - RISQUE D’EXPLOSION
Ne pas connecter ou déconnecter l’équipement alors qu’il est sous tension, sauf si
l’environnement est exempt de concentrations inflammables ou équivalente
MAINTENANCE
Maintenance must be carried out only by qualified personnel. Failure to follow these
instructions may result in personal injury.
CAUTION: RADIO FREQUENCY INTERFERENCE
Most electronic equipment is influenced by Radio Frequency Interference. Caution
should be exercised with regard to the use of portable communications equipment
around such equipment. Signs should be posted in the vicinity of the equipment
cautioning against the use of portable communications equipment.
CAUTION:

Figure 2 Single Channel Schematic
The supply for the field is connected via terminal blocks TB2 (Group 1) and TB4 (Group 2) on
the FTA. This is supplied to the module on sockets SK2 and SK4 via harmonic and transient
protective devices as shown.
The output signals to the field (16-off) are connected from the module on sockets SK1 and
SK3. TB1 and TB3 provide screw terminals for field wiring.
