3.4 Wiring Specifications and Procedures
3.4.1 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.
3.4.2 Power Connections
NOTE
: The recorder is designed to be panel mounted and as such should be considered as fixed
equipment or permanently connected. If permanently connected, disconnection from the supply must
be possible via a customer supplied switch or circuit breaker rated at 120V or 240V (dependent on
local voltage supply) 5A minimum when connected to an AC supply or 30V 2A minimum when
connected to a DC supply. This disconnection device must disconnect all current-carrying
conductors. It 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 3-5 and Figure 3-6).
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 3-5 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 3-6 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 3-7 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 distribution
system.
This unit is equipped with an AC mains fuse internally. If this fuse should blow, it generally
indicates a serious problem with the recorder. THE FUSE SHOULD NOT BE REPLACED BY
AN OPERATOR. The fuse is a quick acting 5 x 20mm type - 2.0 Amps 250 VAC (~).
