Chapter 2 Installation and Wiring
2.3 Wiring Specifications and Procedures
2.3.1 Power Requirements
The Recorder operates on any voltage from 100 to 240 Vac +10%, 50/60 Hz enabling it to be used in most
countries. The maximum apparent power required by the unit is 35 VA.
2.3.2 Power Connections
NOTE: The recorder is designed to be panel mounted and as such should be considered as
permanently connected. Disconnection from the supply must be possible via a customer supplied switch
or circuit breaker. This disconnection device must be included in the panel installation and should be
clearly marked, in close proximity to the Recorder and easily accessible to the operator.
All connections to the Recorder are made to the Rear Terminal Panel. Any wiring carrying hazardous voltages
must conform to all applicable local and national safety codes. AC Mains connection is via an internationally
accepted IEC 320 AC mains connector or screw terminal (Figure 2-4 and Figure 2-5).
WARNING
Ensure all mains power is turned off before proceeding with installation. This unit
is provided with a mating connector for the ac power socket or with a compatible
three wire grounded cable which may be terminated with a plug. Always ensure
the ground wire (green or green and yellow) or ground pin of the plug, is connected
to a low impedance safety ground (earth) within the ac power distribution system
you are using. Always use the recommended mating connector and an approved
three wire cable to connect this unit to the ac mains. Always provide a low
impedance safety ground wire to the ground lug on the rear panel marked .
Figure 2-4 shows the IEC 320 AC mains connector on the rear of the Recorder. The
center pin is the ground termination. If a mating plug is provided, it will be marked
with the Ground, LINE (L) or hot, and NEUTRAL (N) or return. In the United
States, an approved cable with integral plug (NEMA 5-15 P) is provided. In some
instances, a cable with no plug may be provided. In this instance, the user must
connect an approved plug to the cable prior to connecting to the AC source.
Figure 2-5 shows the screw terminal power connections on the rear of the Recorder.
The right terminal is ground, the center terminal is LINE (L) or hot and the left terminal
is NEUTRAL (N) or return. The wire color codes are as follows:
Figure 2-5a shows the ground lug on the rear panel. This screw terminal must be
connected to an earth wire which in turn is connected to the ground or earth of the
AC power distrubution system.
