Safety Instructions
The UPS has its own internal energy source (batteries), therefore the output receptacles may
have electricity present even though the UPS is disconnected from the utility power.
The DC voltage provided from the internal batteries are as follows:
a) GES-801L 24VDC d) GES-202L 48VDC
b) GES-102L 24VDC e) GES-302L 48VDC
c) GES-152L 36VDC
Isolated Ground Wire refers to the bare wire connecting electrical equipment to ground. The
isolated ground wire (green or green with yellow stripe) must meet national wire requirements.
The power plug to connect with the UPS has to be equipped with a ground plug.
The batteries must be replaced or serviced by qualified, knowledgeable, personnel.
Replacement batteries must be the same type, quantity and configuration as the originals.
To avoid explosions, keep open flame and other heat emitting sources away from batteries.
Do not disassemble or damage the batteries. The electrolyte is toxic and especially harmful to
the eyes and skin.
The batteries contain high voltages and currents that are dangerous. To maintain secure
operation and performance of the UPS, the user must exercise basic and regular maintenance.
Please follow the precautions below:
1. Do not remove the UPS cover unless authorized by factory. Removing the cover will void
the warranty.
2. The UPS can only be connected to a 2-pole/3 wire plug.
3. Do not install the UPS in an environment with excessive humidity.
4. Do not allow liquids or foreign objects to get inside the UPS.
5. Allow for air circulation through the UPS. A minimum clearance of 10 cm is required on all
sides.
6. Do not load the UPS with appliances such as a hair dryer, heater, vacuum, kettle, etc.
7. Keep the UPS away from direct sunlight and heat-emitting sources.
8. Install the UPS as close as possible to the load for maximum protection.
9. Storage Requirements
a. Recharge the UPS batteries every 6 months for no less than 8 hours at a time.
b. Under a high ambient temperature environment, recharge the UPS batteries every 3
months for no less than 8 hours at a time
10. High Voltage Risk:
a. High voltages might exist between the battery terminal and the grounding system, if the
battery circuit has not been disconnected from the UPS circuit. Please check this voltage
before connecting.
b. Disconnect the battery wires before proceeding with maintenance. High voltages may be
present between the UPS internal components and batteries even after the input power is
disconnected.
