51209 Revision 2

1.3.3

Protective Earth

Connection to protective earth must be performed via the mounting rail.

1.3.4

Supply Voltage Connection

The supply voltage is 24V DC +10% / -15%.
Max. power consumption of /00 version: 6.5 W; /01 and /04
version: 8.5 W
For connection to 230 / 115 V AC, an external power supply
(e.g. PR 1624/00 or Phoenix Mini Power) is required.

1.3.5

Failure and Excessive Stress

If there is any reason to assume that safe operation of the instrument is no longer ensured, shut it
down and make sure it cannot be used. Safe operation is no longer ensured if any of the following
is true:

-

The instrument is physically damaged

-

The instrument does not function

-

The instrument has been subjected to stresses beyond the tolerance limits (e.g., during storage
or transport).


1.3.6

Fuse

This instrument does not have a replacable fuse. The load cell supply voltage is protected against
short circuit. In case of failure of the load cell supply voltage, disconnect the instrument from the
supply voltage, determine the cause and take remedial measures. Subsequently, the supply voltage
can be switched on again.

1.3.7

Use only screened data cables
Connect screens on both ends with ground
Keep unscreened cable ends short
Connect screen rail to cabinet / housing with
low impedance
Use metal or metalized connector housings
Establish equi-potential bonding between
instruments / system modules (Mandatory for
Ex-applications)
Use standard reference potential
Connect mounting rail to protective earth
Install measure and data cables separately
from power cables

Screen clamp (z.B. Phoenix SK8-D)

Rail connection (z.B. Phoenix AB-SK 65D)

Mounting rail (34mm)

Screen rail (e.g. Phoenix NLS-CU 3/10)
