1.2 SYSTEM DESCRIPTION The MCP SERIES UPS is an advanced True On-Line sinewave Uninterruptible Power Supply (UPS) with automatic bypass. It provides reliable, regulated, transient-free AC power to your sensitive equipment, ranging from computers and telecommuni- cation systems to computerized instruments.
UPS will go to battery mode when AC line power fails and the bar graph displays remaining battery capacity. The number of “ON” LEDs decreases upwards with the decreasing of battery capacity. MCP Control Panel MCP 10001 Rear View Page 3...
1.5 Safety IMPORTANT SAFETY INSTRUCTIONS This manual contains important instructions for MCP SERIES series that SHOULD BE FOLLOWED DURING INSTALLATION AND MAINTENANCE of the UPS and the batteries. The sound pressure level at the operator’s position is equal to or less than 60dB(A).
CAUTIONS: The UPS contains voltages which are potentially hazardous. All repairs should be performed by qualified service person- nel. The UPS has its own internal energy source (battery). The output may be ‘hot” even when the UPS is not connected to the AC supply.
1.6 COMMUNICATION PORT The UPS provides an RS232 serial port to communicate with a host computer. The host computer can monitor the UPS through this RS232 communication port. The data format of RS232 is as follows: Baud Rate : 2400 bps Data Length : 8 bits Ending Code : 1 bit Parity Bit : none...
2.3 WIRING DESCRIPTION The wiring method for the MCP SERIES is shown in Figure A. REAR VIEW Wiring Instructions: 1. Utility panel circuit breaker required is 35A or larger 2. Utility wire guage must be 8 guage or larger. 3. Connect utility per drawing. 4.

OUTPUT CONFIGURATION #5 = 240VAC OUTPUT CONFIGURATION #6 = 120VAC / 240VAC 120VAC When using an isolation tranasformer, ensure that the load is balanced. When using #6 AWG wire 2 in. are required for wire bending space opposite the terminals. 1 1/2 in. for #8 AWG. 3 in.
Possible cause UPS failure Battery is not fully charged, dead battery, charger failure Overloaded Para Systems Inc. MINUTEMAN UPS 1455 LeMay Drive Carrollton, Tx. 75007 ATTN: RMA# Page 10 Problem Call for service Recharge battery for at least 6 hours, retest the backup time.
APPLICATION NOTES 1. START-UP 1. Turn on Input breaker and the Battery breaker (10KVA) on the rear panel after checking the power wiring. The cooling fans should be rotating and the control panel should show the display as below. Figure 1.1-1 Bypass Mode (Load LED display depends of load level) 2.
3. DISPLAYS AND ALARMS 1. Load level and battery capacity is represented by 5 LEDs on the upper half of control panel (the 6th LED means FAULT). (A). When the UPS is in the On-Line mode, the 5 LEDs represent load level. They denote 0%~35%, 35%~55%, 55%~75%, 75%~95% and 95%~105% (from buttom to top) of maximum load capacity.
4. An alarm sounds continuously during an over-temperature condition. Figure 3.4-1 Line Mode 5. Display and alarm for overload. The alarm will sound once every 0.5 seconds during an overload condition. While in inverter mode, the alarm can be silenced by pressing the “OFF”...
7. Alarm for abnormal input voltage. A) During Start-up, the Line LED will flash if the input voltage drops below 185V or above 261V. Pressing the “|” button will not switch the UPS from Bypass Mode to Inverter Mode. (B)During operation, the UPS will switch from Inverter Mode to Battery Mode if the input voltage drops below 170V or above 276V.
10. Inverter STS short alarm. The system will detect if the inverter STS is shorted when the “ON” button on the control panel is pressed. If the STS short is detected, the display shows as below and the alarm sounds continuously. Figure 10.1 Inverter STS short alarm LIMITED PRODUCT WARRANTY Para Systems Inc.
