SL Power Electronics GPM41 - Manual (Page 2)

GROUNDING: Protection Class I requires that the ground terminal be bonded to Protective Earth in
the end application. Using this terminal for the primary system earthing terminal is not recommended.
The Power Supply may be attached to system ground by soldering a grounded wire directly to a .098
inch hole marked with a ground symbol near T1. Alternatively, #4 screws (max 0.22 inch head
diameter) and metal spacers (3/16 inch diameter, 1/4 inch minimum length) should be used to mount the
power supply to grounded metal surfaces (Protective Earth). When mounting surfaces are not grounded
or spacers are non-metallic, electrically connect the two metallic mounting pads on the pwb together.
OUTPUTS: Either the + or - output should be connected to Protective Earth in the end application.
The output is intended for Protectively Earthed Signal Output and Intermediate Circuits only. The
output is not acceptable for patient connection without additional isolation. The DC output is SELV
under normal and single fault conditions.
OVERVOLTAGE PROTECTION: The output is monitored for an overvoltage condition. In some
applications where an overvoltage condition could result in a hazard as defined in applicable safety
standards, redundant or additional overvoltage protection may be required. Consult factory for details.
DIELECTRIC STRENGTH TEST CAUTION: When performing Dielectric Strength Tests,
catastrophic failure of the unit may result if a Dielectric Strength test voltage greater than 1800 V ac is
applied between primary and secondary circuits. The components providing isolation from primary to
secondary cannot be tested while installed in the power supply without overstressing basic (primary to
ground) insulation. All isolating components are individually 100 % tested at 4800 V ac prior to
installation.
MAINTAINING ISOLATION: The creepage distance between primary and ground is 4 mm minimum;
between primary and secondary circuits is 8 mm minimum. Secondary to ground creepage is not defined
or controlled. The output common is bypassed to ground using a 0.001 µF 1 kV capacitor. The required
creepage and clearance distances from primary circuits to ground and secondary circuits must be
maintained after installation to preserve the intended safety.
TEMPERATURES: The maximum operating temperatures of certain safety components, as defined in
the applicable safety standards, must not be exceeded after installation to preserve the intended safety.
The output power, ambient air temperature and the availability, amount, direction and/or restriction of
airflow influence the temperatures of these components.
