HC350S, HCINT350S Series Power Module Application Guidelines
SAVE THESE INSTRUCTIONS – This manual contains IMPORTANT SAFETY
INSTRUCTIONS for that should be followed during installation and maintenance of the
UPS and batteries.
The HC350S and HCINT350S series of hospital cart power modules are designed to
provide AC voltage output power from either utility provided AC input voltage or from
inverting 12VDC power from a sealed lead acid battery. To ensure proper operation the
following guidelines should be observed:
1. The power module can support AC loads up to a maximum of 400VA or 300W.
2. The power module charger is intended to be used with a 12V sealed lead acid
absorbed glass mat (AGM) battery with a 33AH to 66AH rating. Batteries rated
at less than 33AH are not recommended since the charger current of 12A would
reduce the battery cycle life of smaller batteries.
3. Adequate provision for airflow needs to be provided at both the inlet and outlet
vents of the power module. There should be at least 0.5 inches of clear space
on the fan end and on the vented end of the power module. A baffle or air
deflector is recommended at the fan end so that the air intake is raised at least 6
inches above floor level to prevent dust accumulation inside the power module.
4. The power module may be mounted in any orientation. Four 8-32 threaded
inserts are provided on the surface with the AC input cord to facilitate mounting.
5. The AC voltage input and output connections are made with user supplied cables
to the IEC input and output connectors on the power module. Use only with
approved plug/cord sets according to the equipment electrical ratings. No
external fusing is needed since safe operation is assured by internal non-
replaceable 10A fuses. However, if a customer wishes to prevent the internal
fuses from blowing in the event of an extreme overload, then an external fuse or
circuit breaker rated at 6A to 10A (120VAC models) or 3A to 5A (230V models)
should be provided on the AC voltage input.
6. The 12V battery input is made with a user supplied cable to the Anderson DC
connector on the power module. Proper polarity must be observed. The
recommended wire size is 8AWG in order to keep the voltage drop in the cable to
less than 0.1V. The length of cable between the battery and the power module
should be less than 30 inches. A user supplied 40A to 50A automotive style fuse
is required in the positive lead of the battery (within 18 inches of the battery
positive terminal).
7. Additional bonding is needed to connect the battery negative terminal to the case
of the power module. The wire (or metal frame of the cart) should be short (less
than 18 inches) and preferably of the same gauge as the other battery wires
