2.5 Input Connections
In general, all wiring connections are made to the instrument after it is installed. Avoid
electrical shock. AC power wiring must not be connected to the source distribution
panel until all wiring connection procedures are completed.
Caution: This equipment is designed for installation in an enclosure which
provide 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 unauthorized personnel.
Power should be connected via a two pole isolating switch (preferably situated
near the equipment) and a 1A fuse, as shown in Figure 2-7.

Line Supply
The instrument will operate on 90-264V AC 50/60 Hz electrical line supply. The power
consumption is approximately 4 VA. If the instrument has relay outputs in which the
contacts are to carry line voltage, it is recommended that the relay contact line supply
should be switched and fused in a similar manner but should be separate from the
instrument line supply.
