CAUTION STATEMENTS
TMS7 SERIES ME00070B 3
Caution Statements
WARNING - ELECTRICAL SHOCK
HAZARD
The TMS7 contains dangerous voltages when
connected to line voltage. Only a competent
electrician should carry out the electrical
installation. Improper installation of the motor
or the TMS7 may cause equipment failure,
serious injury or death. Follow this manual
and National Electrical Codes (NEC
®
) and
local safety codes.
CAUTION
GROUNDING AND BRANCH
CIRCUIT PROTECTION
It is the responsibility of the user or person
installing the TMS7 to provide proper
grounding and branch circuit protection
according to the National Electric Code
(NEC
®
) and local codes.
It is the installers responsibility to adhere to all instructions in
this manual, to follow good electrical practice and to seek advice
before operating this equipment in a manner other than as
detailed in this manual.
• Ensure that the TMS7 is completely isolated from the power
supply before attempting any work on the unit.
• Do not apply voltage to the control input terminals. These
are active 12/24VDC inputs and must be controlled with
potential free circuits.
• Ensure contacts/switches operating the control inputs are
suitable for low voltage, low current switching ie, gold flash
or similar.
• Ensure cables to the control inputs are segregated from AC
power and control wiring.
• Entry of metal swarf into the cabinet can cause equipment
failure.
• Do not connect Power Factor Correction capacitors to the
output of the TMS7. If static power factor correction is
employed, it must be connected to the supply side of the
TMS7.
• Before installing the TMS7 without a line contactor ensure
such connection meets local regulations and by-laws.
• If installing the TMS7 within a non-ventilated enclosure a
bypass contactor must be utilised to prevent excessive heat
build-up.
• If installing a by-pass contactor ensure phase connections
are correctly made
ie L1B-T1, L2B-T2, L3B-T3
• Removing control voltage resets the thermal model.
The examples and diagrams in this manual are included solely for illustrative
