2.1 Installation
WARNING - INSTALLATION AND MAINTENANCE SHOULD ONLY BE PERFORMED BY
PROPERLY TRAINED OR QUALIFIED PERSONNEL.
2.2 Initial Inspection
Bitronics instruments are carefully checked and "burned in" at the factory before shipment.
Damage can occur however, so please check the instrument for shipping damage as it is
unpacked. Notify Bitronics LLC immediately if any damage has occurred, and save any
damaged shipping containers.
2.3 Protective Ground/Earth Connections
There are two chassis ground points that MUST be connected to Earth Ground (refer to
Figure 8, pg. 78). The first is the Protective Ground (Earth) terminal (terminal 2) on the
Power Supply input. The minimum Protective Ground (Earth) wire size is 2.5 mm
2
(#12
AWG). The second is the mounting flange. Bitronics LLC recommends that all grounding
be performed in accordance with ANSI/IEEE C57.13.3-1983.
2.4 Instrument Mounting
The unit should be mounted with four #10-32 (M4) screws.
Make sure that any paint or
other coatings on the panel do not prevent electrical contact. The device is intended to be
connected to earth ground at the mounting plate. See Section 2.3.
2.5 Surge Protection
Surge protection devices are incorporated into the power supply. See Section 2.3 for
grounding/earthed recommendations. If the unit is to be powered from a VT, it is
recommended that one side of the VT be grounded at the instrument following ANSI/IEEE
C57.13.3-1983. See Section 6.5 for fuse recommendations.
2.6 Cleaning
Cleaning the exterior of the instrument shall be limited to the wiping of the instrument using
a soft damp cloth applicator with cleaning agents that are not alcohol based, and are
nonflammable and non-explosive.
