Special Conditions for Safe Use
1.
The DPI 620G-IS USB Client Connection must only be connected to external
apparatus within a Safe Area with U
2.
When a remote sensor is powered using the Channel 2, 15V, U
remote sensor must be disconnected from all other sources of power.
3.
The Channel 2, V terminals can be connected to a FISCO System if the power for the
system is provided from the DPI 620G-IS Channel 2, 15V, U
electrical parameters of the field devices are compatible with those of the
DPI 620G-IS.
4.
The DPI 620G-IS should not be connected to a powered FISCO system unless its
defined electrical parameters are compatible with the DPI 620G-IS.
5.
If the Channel 1 Terminals and the Channel 2 Terminals are used together then they
must always be connected as separate Intrinsically Safe Circuits.
6.
The rechargeable battery pack may be removed from or replaced in a DPI 620G-IS
within a hazardous area.
7.
The rechargeable battery pack must be removed from the DPI 620G-IS for recharging
in the safe area using only the Socket 3 charging contacts and the Druck charger with
U
= 254 V. No connections must be made to the IS outputs.

8.
Both the MC 620-IS Dual Transducer Carrier, or the PV 62X-IS Series Pressure Station
have a location for either one or two transducers which screw into the pressure
connection and the two slip rings on the lower face of a transducer make contact with
two spring loaded pins. When either a MC 620-IS Dual Transducer Carrier, or the
PV 62X-IS Series Pressure Station is connected to a DPI 620G-IS Advanced Modular
Calibrator, these pins are energised and do not meet the requirements of at least
IP20. Therefore it is a requirement of certification that before either the MC 620-IS
Dual Transducer Carrier or the PV 62X-IS Series Pressure Station is connected to the
DPI 620G-IS Advanced Modular Calibrator, a PM 620-IS Transducer or a metallic
Dummy Pressure Transducer is screwed into any vacant positions and remains in
position until the assembly is removed from the DPI 620G-IS Advanced Modular
Calibrator.
INFORMATION
IECEx approval that is "Part of" the DPI 620-IS approvals.
(Baseefa10ATEX0010X / IECEx BAS 10.0002X).
The PV 62X-IS Series Pressure Station has separate ATEX and IECEx
approval (Baseefa10ATEX0011X / IECEx BAS 10.0003X).
