Installation of the signal converter
2.1
Please note the following information concerning installation and operation of the IFC 110 PF
•
Electrical connection in conformity with VDE 0100 / EN 61010-1
"Regulations governing heavy-current installations with rated voltages up to 1000 V"
or equivalent national standard.
Refer
to connection diagram, sect. 1.5.6, for power connection to signal converter.
Warning:
Instrument must be properly grounded to avoid personnel shock hazard
•
Do not cross or loop the
cables in the connection box.
Use separate PG or NPT screwed conduit entries for each cable.
•
On normal customer orders, the GK (primary constant) of the signal converter is factory-set to match that of the primary head
with which it has been ordered. The GK is noted on the primary head nameplate and also shown on the converter nameplate.
These instruments should be installed together.
2.2
Choice of installation location
•
Do not expose signal converter to direct sunlight. Install a sunshade if necessary.
•
Do not expose to intense vibration.
•
Ensure adequate cooling of IFC 110 PF unit when installed in switchgear cubicle(s), e.g. use heat exchangers.
•
Install signal converter as close as possible to the primary head.
•
Use factory-supplied standard signal cable (type DS), standard length 10 m (30ft). For longer lengths and bootstrap signal
cable (type BTS, optional), refer to sect. 1.5.3.
•
Use factory-supplied data cables, standard length 10 m, for the RS485 interface between primary head and signal converter.
2.3
Connection to power
•
Note information given in sect. 2.1!
•
Note the information given on the
instrument nameplates
on the signal converter (voltage, frequency!).
2.4
Connection between IFC 110 PF and IFS 4000 PF
•
Data interface cable; for general information and max. length see sect. 1.5.2 and 1.5.5; for connection see sect. 1.5.6.
•
Signal cable type DS with double shielding or type BTS with triple shielding (optional); for general information and max. length
see sect. 1.5.3 and 1.5.5; for connection see sect. 1.5.6.
•
Field power supply cable; for minimum cross-section (A
F
) and length see sect. 1.5.4 and 1.5.5; for connection see sect. 1.5.6.
