1.3.1
Mains (Line) In put
The instrument will operate on 96 - 264V AC 50/60Hz mains (line) supply. The power
consumption is approximately 4 VA.
CAUTION:
This equipment is designed for installation in an enclosure
which provides adequate protection against electric shock. Local
regulations regarding electrical installation should be rigidly observed.
Consideration should be given to prevention of access to the power
terminations by unauthorised personnel. Power should be connected
via a two-pole isolating switch (preferably situated near the equipment)
and a 1A fuse, as shown in Figure 1-5.
If the instrument has relay outputs in which the contacts are to carry
mains (line) voltage, it is recommended that the relay contact mains
(line) supply should be switched and fused in a similar manner but
should be separate from the instrument mains (line) supply.
1.3.2
24V (Nomi nal) AC/DC Sup ply
The supply connections for the 24V AC/DC version are shown in Figure 1-6. Power
should be connected via a two-pole isolating switch and a 315mA slow-blow fuse
(anti-surge Type T).
The nominal 24V supply may be in the following ranges:
24V (nomi nal) AC 50/60Hz -
20 - 50V
24V (nomi nal) DC -
22 - 65V
