Do not change the external or internal grounding connections. Tampering with or
disconnecting these connections could endanger you and damage the TriPlus RSH.
The instrument is properly grounded in accordance with these regulations when shipped. To
ensure safe operation, you do not must make any changes to the electrical connections or the
instrument's chassis.
Do not turn the instrument on if you suspect that it has incurred any type of electrical
damage. Instead, disconnect the power cord and contact a Thermo Fisher Scientific
representative for a product evaluation. Do not attempt to use the instrument until it has been
evaluated. Electrical damage might have occurred if the TriPlus RSH shows visible signs of
damage, exposure to any liquids or has been transported under severe stress.
Damage can also result if the instrument is stored for prolonged periods under unfavorable
conditions: for example, subjected to heat, moisture, and so on. Ensure that the power
supply/controller unit is always placed in a clean and dry position. Avoid any liquid spills in
the vicinity.
Before attempting any type of maintenance work, always disconnect the power cords from the
power supply(ies) if optional devices are installed. Capacitors inside the instrument might still
be charged also if the instrument is turned off.
To avoid damaging electrical parts, do not disconnect an electrical assembly while power is
applied to the TriPlus RSH. After the power is turned off, wait approximately 30 seconds
before you disconnect an assembly.
The instrument includes a number of integrated circuits. These circuits might be damaged if
exposed to excessive line voltage fluctuations, power surges or electrostatic charges, or both.
Never try to repair or replace any components of the instrument without the assistance of a
Thermo Fisher Scientific representative. There are no operator-serviceable or replaceable parts
inside the power supply(ies) or in the TriPlus RSH. If a power supply is not functioning,
contact a Thermo Fisher Scientific representative.
The power supplies for the TriPlus RSH, the Temperature Controlled Drawer have the
symbols
I/O
on the label for the power switch to indicate ON/OFF. If a Temperature
Controlled Drawer is installed in combination with a TriPlus RSH, a second power supply is
active in the complete system. Turning OFF the two power supplies, or pulling the two power
cords in an emergency, stop the entire TriPlus RSH.
It is important that the power supply(ies) is in a location where the power ON/OFF switch is
accessible and easy to operate, and where it is possible to unplug the AC power cord from the
power supply/wall outlet in case of emergency.
