2.1.1.2 Power Input
The installation of a 3600 / 3600M instrument should only be performed by
personnel specialized and authorized to work on electrical installations, in
accordance with relevant European and/or national regulations.
In accordance with safety standard EN 61010-1, it must be possible to disconnect
the power supply of a 3600 / 3600M instrument in its immediate vicinity.
While the instrument’s electronics are well shielded, it is still advisable to locate
the instrument as far as possible from any source of electromagnetic perturbation.
AC Power Input
AC power connections for panel or 19" rack mount instruments use a standard
detachable cable on the rear panel of the instrument.
For panel or 19" rack mount instruments, a power supply cable, type H05VV-F 3
X 0.75 mm

, which is supplied with the instrument, must be used. The length of
the cable should be three meters maximum and it should have a separable plug
(with three connectors, L+N+PE), without a locking device, to mate with a socket
outlet in the building. The cable and the plug must conform to an appropriate
European or national standard.
10–30 VDC Power Input
10–30 VDC powered panel or 19" rack mount instruments have a male Binder
connector on their rear panel. It accepts DC power as follows:
Pin 1: DC Return
Pin 2: Earth (Chassis)
Pin 3: Not connected
Pin 4: 10–30 Volts DC
Male Binder receptacle, rear panel of instrument
The user must make the necessary power wiring connections, using the female
Binder plug supplied with your system. User-supplied power cable can have an
outer diameter between 5 and 8 mm.
To disassemble the plug, squeeze the two clips located in the middle of the plug
(position “C” below). This reveals numbered wiring connections inside, to be
matched one-to-one with the diagram above.

2.1.1.3 Electrical Signal Connections
Panel or 19" rack mount instrument connections to the oxygen sensor and
external pressure sensor use the pre-wired LEMO connectors on the rear panel of
the instrument. The LEMO connector pin assignments are identified in section
2.1.4, Instrument Connectors. Instructions for wiring the LEMO plugs are in
section 2.1.6, LEMO Connector Assembly Instructions.
Connections for RS-232, recorder (analog) output, and alarm relays use the
stainless steel watertight glands on the instrument rear panel. These connections
must be hard-wired to a terminal strip inside the instrument. Instructions for
wiring these outputs through the cable glands are in section 2.1.7, Cable Gland
Wiring Instructions.
