Modulon DPH Series 3
1. Product Introduction
The Delta External Battery Cabinet is applicable to DPH-60K-LV and DPH-105K-LV UPS
and should be used with the Delta Battery Module (optional).
When the UPS is operating, during a power outage, the battery modules will provide DC
power to maintain the UPS operation to supply power to the critical loads.

2. Important Safety Instructions
Servicing of batteries, battery modules and battery cabinet must be performed or
supervised by qualified service personnel knowledgeable in batteries, battery
modules and the battery cabinet as well as their required precautions. Keep
unauthorized personnel away from batteries, battery modules and the battery
cabinet.
A battery can present a risk of electric shock and high short-circuit current.
To reduce the risk of fire or electric shock, install the battery modules in a
temperature and humidity controlled indoor area free of conductive contaminants.
Forbid opening or removing the chassis of both battery modules and Battery
Cabinet to avoid high voltage electric shock.
The risk of dangerous high voltage is possible when the Battery Cabinet still
connect to the UPS even though the UPS is disconnected from the mains. Do
not forget to turn off the inbuilt breaker of Battery Cabinet to completely cut off
the battery source.
Make sure Battery Cabinet disconnect to UPS before performing battery modules
replacement.
Only use the battery modules from Delta. Never use old and new battery modules
at the same time.

Modulon DPH Series 5
The number of batteries/battery modules must meet UPS requirements.
The AH of Battery Cabinet must meet or larger than UPS requirements. It is
determined by the number of battery modules.
Do not reverse or short circuit the polarity +, –, and N when connecting the
batteries because this will destroy the device and constitute a risk of electric
shock or fire.
Use a voltage meter to measure whether the total voltage, after battery modules
connection, is around 180Vdc. (V+N or VN-)
The external slits and openings in the battery modules are provided for ventilation.
To ensure reliable operation of the battery modules and to protect the Battery
Cabinet from overheating, these slits and openings must not be blocked or
covered. Do not insert any object into the slits and openings that may hinder
ventilation.
Do not allow liquid or any foreign object to enter the battery modules and Battery
Cabinet.
Do not place beverages or any other liquid-containing vessels on or near both of
battery modules and Battery Cabinet.
Do not dispose of the batteries or battery modules in a fire. The batteries/battery
modules may explode.
Do not open or mutilate the batteries or battery modules. The released electrolyte
is harmful to the skin and eyes and may be toxic.
Observe the following before replacing battery modules:
(1) Remove watches, rings, or other metal objects.
(2) Use tools with insulated handles.
(3) Wear rubber gloves and boots.
(4) Do not lay tools or metal parts on the top of batteries.
(5) Disconnect charging source prior to connecting or disconnecting batteries’
terminals.
