2.4 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 authorized
personnel. Power should be connected via a two pole isolating switch (preferably
situated neat the equipment) and a 1 A fuse, as shown in Figure 2-7.

Main Supply
The instrument will operate on 90-264V AC 50/60 Hz 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
be switched and fused in a similar manner, but separate from the instrument line
supply.
