2 Bulletin 1405 (M610) Operating Instructions
Installation Only qualified personnel should install and wire this equipment. Refer
to the following safety guidelines prior to installation.
1. Install your MiniPowermonitor within a suitable enclosure. Make
sure the enclosure provides adequate clearance for ventilation
and wiring of the module. Refer to Dimensions on page 6 for
dimensions and spacing guidelines for the MiniPowermonitor.
2. Determine your wiring mode and install wiring between the
MiniPowermonitor and your power system. Refer to Input
Connections on page 3 for more information.
3. Configure the current transformer (CT) ratios to match those
used in your power system connections. Refer to Current
Transformer Ratio Setting and Display Test on page 4 for more
information.
Grounding
MiniPowermonitors do not need to be grounded because of the
isolated enclosures. Follow all local requirements for grounding of PT
and CT secondaries.
ATTENTION
Only qualified personnel, following accepted safety
procedures, should install and wire the
MiniPowermonitor. Before beginning any work,
disconnect all sources of power and verify that they
are de-energized and locked out. Failure to follow
these instructions may result in personal injury or
death, property damage or economic loss.
ATTENTION
Never open a current transformer (CT) secondary
circuit with primary current applied. Wiring between
the CTs and the MiniPowermonitor should include a
shorting terminal block in the CT secondary circuit.
Shorting the secondary with primary current present
allows other connections to be removed if needed.
An open CT secondary with primary current applied
produces a hazardous voltage, which can lead to
personal injury, death, property damage or economic
loss.
